Mesa Families CountThe Silent Part Out Loud: doing the math

The silent part, out loud

Doing the math on closing Mesa.

The analysis highlights two serious risks for our children and families:

  1. Everyone stays together in a building nearly at capacity with almost no room to grow.

    Everyone moves into the current Bear Creek building, with its open-plan layout. If today’s K–4 students return and the incoming kindergarten matches this year’s, the calculation gives:

    490 children for 492 places.

    Just two places to spare.

  2. ORDozens of current Mesa students are at risk of losing their place.

    The BVSD proposal projects 392–445 students, 45–98 fewer than the benchmark.

    The projections and proposed placement rules suggest that current Mesa open-enrollment students could lose their places in the combined school next year.

Four steps walk through the basic math.

Parent video about classroom capacity

Video prepared by other thoughtful Mesa parents.
How the numbers were calculated

The video applies each school’s own 2025–26 enrollment mix to its part of the same 490-child benchmark used in this analysis, estimating about 55 Bear Creek and 34 Mesa outside-area open-enrollment students. These estimates include assumed incoming kindergarten; they are not observed counts of currently enrolled students, counts of families, or admission decisions.

Start with the same children. The August 28 preliminary count has 264 Bear Creek and 158 Mesa children in K–4. Assume those 422 children return and a new kindergarten matches the current 43 + 25 = 68: 422 + 68 = 490. This conditional benchmark allows no additional net cohort growth. Historical cohort growth could raise it; these data do not identify how much growth comes from new open enrollment.

Use each school’s historical mix. The 2025–26 elementary matrix counts 312 pupils at Bear Creek and 224 at Mesa. Its rows show the school attended and its columns show where pupils live. Bear Creek’s school-level OE count is 83, including 27 Mesa-area residents: 83 − 27 = 56 outside the combined area. Mesa’s is 58, including 16 Bear Creek-area residents: 58 − 16 = 42.

Apply each share to that school’s benchmark. Bear Creek contributes 264 returning pupils + 43 assumed new kindergartners = 307; Mesa contributes 158 + 25 = 183. Apply the same school-wide K–5 share to both returning pupils and assumed new kindergarten: 307 × 56/312 = 55.1 Bear Creek OE, and 183 × 42/224 = 34.3 Mesa OE. The video displays these as 55 and 34.

Here, “OE” means outside the proposed combined attendance area. Students attending across the Mesa/Bear Creek boundary count as residents of the combined area. This differs from BVSD’s school-level OE definition. The combined area includes both schools’ areas and the two Bear Creek optional areas. District placements are a separate category.

Apply each school’s 2025–26 K–5 shares to its own returning-plus-kindergarten benchmark
Category2025–26 category countsCalculation2027–28 estimate

Mesa outside-area OE42183 × 42 / 22434.3
Total312 + 224 = 536307 + 183490.0

The gray, unlabeled segment represents approximately 21 district-placement pupils. Video labels are rounded independently to whole students: 380 residents + 21 placements + 55 Bear Creek OE + 34 Mesa OE = 490. The table shows one decimal; calculations and chart proportions use unrounded values. Removing the modeled Mesa segment would leave 455.7, about 10.7 above 445.

The wording that Mesa students are “gone” refers to their exclusion from the district’s projection, including its upper endpoint of 445. It does not establish that all of them will be denied places. The subtraction above illustrates the projection gap, not a forecast of departures. September 15 staff explanations say RISE pupils are included in the projection. Read the enrollment explanation.

The video’s 418-seat calculation assumes three of the 20 rooms are used for RISE and AIM: 17 × 24.6 = 418.2. The room count and pupils per room follow the district’s September 15 explanation (20 × 24.58 ≈ 492). This illustrates a classroom-space question; it does not establish a replacement for BVSD’s stated 492-place capacity. The district has yet to share plans for this room count. Program pupils must be counted once. Read the classroom analysis.

Walk through the basic math · Step 1 of four

They’re already our school community.

Let’s start with a simple assumption: the children who can return next year do return.

First, the children coming back.

The current Mesa and Bear Creek schools have 534 children in the preliminary count. Subtract the 112 fifth graders moving on to middle school.

That leaves today’s kindergarten through fourth graders, our returning children.

Then, a new class of kindergartners.

Use this year’s combined kindergarten, 68 children, as a simple estimate for next year’s incoming class.

This assumes all current K–4 children return, with no other net enrollment change. It is a benchmark, not a forecast.

And the room we have?

The current Bear Creek building’s stated capacity is 492.

490 children.
Two places to spare.

And that is only a building-wide total. Particular grades or classrooms could already be full. Being below 492 does not guarantee that every child fits in the classroom and program they need. See the grade-by-grade math →

2027–28 · if everyone returns

They all count.

Our school community, with two places left.
Each little student represents one child.

490 students and two empty places264 returning Bear Creek students, 158 returning Mesa students and 68 new kindergartners total 490. Two empty boxes represent the unoccupied places within the stated capacity of 492.

BVSD’s August 28, 2026 preliminary count: Bear Creek K–4 = 264; Mesa K–4 = 158. Combined fifth grade = 112; kindergarten = 43 + 25 = 68. The enrollment count is an observation; carrying it into 2027–28 is our stated assumption. Capacity comes from the August proposal, p. 51.

Step 3 · Now look at the proposal

Where did the other
children go?

Our everyone-returns benchmark490children in 2027–28
BVSD’s projected enrollment392–445children in 2027–28
That’s 45–98 fewer children.
What assumptions account for the difference?

On September 15, BVSD staff clarified that the enrollment projection excludes ALL current Mesa open-enrollment students who live outside the proposed combined attendance area—even at the upper end of 445. 02:03:07 · recording; 02:08:48 · recording.

The FAQ calls this:

“managing choice enrollment beginning in 2027-28”

Read together, the FAQs and meeting explanation mean that managed enrollment can leave current Mesa families from outside the combined attendance area without places. Those families receive application priority, not guaranteed admission. Staff said current Bear Creek students can remain, including those already open-enrolled there. FAQs · 02:03:19 · recording; 02:08:48 · recording.

Families deserved a direct, respectful warning. The proposal should have told current Mesa open-enrollment families living outside the combined attendance area plainly that they were not included in the projections and they face a high risk of being turned away from the combined school next year. This clarity came only a week before the vote, limiting families’ ability to contribute during the public feedback period.

Being excluded from the projection does not mean an application has been denied. Staff clarified the broad approach; the exact calculation behind the 45–98-student gap remains unexplained.

Why is turning away open-enrolled students a likely outcome?

The meeting clarified whose enrollment is excluded from the projection; it did not establish how many current Mesa applicants will receive places. The calculation below asks whether voluntary departures alone could explain the gap, holding incoming kindergarten at the benchmark level. Limiting new choice admissions could also make room, so these net-loss calculations are not predicted turnaway counts. 02:03:03 · recording; 02:08:48 · recording.

The district itself says its projections account for managing choice enrollment when buildings approach capacity. That is a concrete reason for concern. Read the district’s explanation.

Could families choosing not to enroll explain the gap instead? Keep the benchmark’s assumption of 68 incoming kindergartners. Compared with today’s 422 children in K–4, next year’s grades 1–5 would need to be smaller by:

  • 45 students, or 10.7%, to reach the proposal’s upper estimate of 445.
  • 98 students, or 23.2%, to reach its lower estimate of 392.

Those are net losses, after any new arrivals offset departures. Across 11 year-to-year comparisons in the district’s 2014–15 through 2025–26 October counts, the largest comparable decline was 21 students, or 3.9%, entering the 2020–21 pandemic school year. That compares the two schools’ combined K–4 count with grades 1–5 the following year, excluding graduating fifth graders and incoming kindergarten. In most years, these combined K–4 cohorts grew as they advanced to grades 1–5. Over the last ten completed annual transitions, from 2015–16 through 2025–26, the average net gain was 25.9 students per year across the two schools. Net growth includes new arrivals; it does not tell us how many current students left. Ten-year calculation and source references · Historical counts and method.

The required decline would be larger than any in this twelve-year record, even the decline entering the COVID year. A smaller incoming kindergarten could explain part of the gap. But even with 58 kindergartners, the smallest combined kindergarten in those twelve October counts, reaching 445 would still require a net loss of 35 students, or 8.3%, from the returning grades.

These grade totals do not track individual children or tell us why families leave. Consolidation could change families’ choices, and the current starting count is preliminary. BVSD should explain the assumed departures, kindergarten intake and placement restrictions instead of leaving families to connect the dots.

Meanwhile, relocating Community Montessori and High Peaks farther from this neighborhood could increase demand for the combined school. A substantial reduction in attendance should be explained, not simply assumed. See the proposed relocations.

Why might Mesa students be at particular risk?

Mesa is identified as the closing school, so its families face the proposed closure-placement rules. The implications depend on where a child lives:

  • Inside the combined attendance area: Mesa children are assured places as residents under the approach described, including children currently open-enrolled across the Mesa/Bear Creek boundary.
  • Within BVSD, outside the combined area: current Mesa children have a neighborhood-school assignment and may apply to the combined school with priority. A place there is not guaranteed.
  • Outside BVSD: current Mesa children must apply again through open enrollment with priority. Offers depend on space, programs and staffing.

Current Bear Creek students can remain, including those already open-enrolled there, under the approach staff described. Staff said “we wouldn't touch the kids that are already in the building”, while discussing limits on new applications. 02:03:19 · recording.

Under this approach, managed enrollment could mean turning away current Mesa outside-area students while current Bear Creek students retain their places. How many Mesa applicants can be accommodated remains unresolved.

Step 4 · The consequences for our community

Something has to give.
Our children will feel it.

For a child, this can mean a crowded school day or saying goodbye to friends. These are the consequences behind the numbers.

Together.
But squeezed.

1. If everyone attends together

Friends stay together in the current Bear Creek building, nearly at capacity, in an open-plan layout, with almost no cushion for more children.

Will children have enough quiet space to concentrate, and will teachers have enough space to help?

2. If current Mesa children lose their places

More room.
More goodbyes.

2. If current Mesa children lose their places

The building has more room because some children are no longer there. For a current Mesa family, that can mean losing friends, familiar teachers and the community they chose.

The children who stay lose good friends, too. Turning away currently enrolled students breaks up friendships on both sides. The loss reaches the whole school community.

Children now attending the receiving school are affected too: their friendships, routines and school culture would change.

Illustrations imagine possible consequences. They do not depict an actual school or a decision already made.

Capacity is also about what a school day feels like.

The open classroom layout in the current Bear Creek building makes noise and distraction especially important. Children there already use headphones or earmuffs to block out noise.

Many Mesa families chose Mesa in part for a smaller setting with separate classrooms. When we talk about “fitting,” we should be talking about our children’s ability to learn, too.

We need a clear, public capacity and staffing plan showing that every grade and program can be supported.

What does research say about learning and belonging?

Class size can matter. Tennessee’s randomized Project STAR found achievement benefits from smaller early-grade classes. That supports taking class size seriously; it does not estimate the effect of this particular merger. Read the study.

Noise is a learning issue. A study that alternated open and acoustically divided classrooms found faster reading-fluency development in the enclosed setting, with larger differences for children with weaker attention or speech perception in noise. It did not study the current Bear Creek building. Read the study.

The receiving community matters, too. A Chicago study found academic disruption and reported grief and difficulties combining school cultures among students and staff from both closing and welcoming schools. Some effects recovered; absence and suspension rates did not change. Outcomes depend on context and the schools children enter. These findings are reasons to demand a transition and well-being plan, not a prediction of identical effects here. Read the study.

Even more math · Why the pressure could grow

Two spare places
don’t leave much room for change.

Community Montessori moves away.

The proposal moves Community Montessori from Gillaspie Drive to Aurora 7. The move is likely to increase demand for a nearby neighborhood school.

High Peaks moves farther east.

High Peaks would move from Aurora 7 to Douglass, farther from the Mesa and Bear Creek neighborhood. Some local families may choose to stay closer to home.

The proposal’s own numbers rise.

BVSD’s enrollment range rises from 392–445 in 2027–28 to 403–462 in 2030–31. Families need a plan for later years, too.

The moves are proposed district actions. Their effects on local demand are expectations, not measured enrollment increases.

Forecasts are uncertain.

BVSD’s forecasts for the same school year, 2029–30, changed between its October 2025 presentation and February 2026 report: Mesa fell from 224 to 202 students, while Bear Creek rose from 272 to 310.

These are revised forecasts for the separate schools, not changes in actual enrollment. A plan with almost no room to grow needs to account for forecast uncertainty. Compare the district’s tables.

A longer-term question

What about CU South?

CU South is planned to include housing for faculty, staff and students. CU says university construction could begin no sooner than roughly 2030, after flood-protection work; site planning has not begun. That is a construction date, not a housing move-in date.

What student population, attendance boundaries and timing does BVSD assume? Is any of that demand already in its projections? No extra CU South children are added to the calculations here. Check the university’s timeline.

Already above the projection.

About 10 more resident children than the proposal’s upper total of 462, before adding any outside-area students or placements.

How does that total make room for open enrollment and placements?

The current Bear Creek building’s stated capacity is 492, leaving about 20 places in this scenario. Exceeding the proposal’s enrollment projection is different from exceeding the building’s capacity.

In 2025–26, the two schools also enrolled 98 choice students from outside the combined area and 23 placements. Those children’s place in the plan should be visible.

These are historical groups, not a fixed cohort to add to 2030. Children graduate and families’ choices change.

Sources, alternatives and exact arithmetic

The 2025–26 elementary enrollment-pattern matrix contains 502 residents in the four areas: Bear Creek, Mesa, Optional Bear Creek/Mesa and Optional Bear Creek/Creekside. Of those, 415 attended the two current schools, 27 attended Montessori and 12 attended High Peaks. The proposal projects 522 residents in 2030–31 and gives a total enrollment range of 403–462 (p. 51).

The main case is 522 × (415 + 27 + 12) ÷ 502 = 472.09, or 95.95% of capacity. It exceeds the proposal’s upper total by 472.09 − 462 = 10.09 and leaves 492 − 472.09 = 19.91 places within the building. Calculations use exact counts before rounding.

  • No shift from either focus school: about 432 residents attend, leaving about 30 within the upper projection and 60 within capacity.
  • Half of both historical shares shifts: about 452 residents attend, leaving about 10 within the upper projection and 40 within capacity.
  • The full Montessori share shifts, without a High Peaks shift: about 460 residents attend, leaving about 2 within the upper projection and 32 within capacity.
  • Both full shares shift: about 472 residents attend, about 10 above the upper projection and 20 below capacity.

The shifts are scenarios with no assigned probabilities. Smaller shifts produce lower enrollment. Could residents alone fill the building? The separate future scenarios add possible increases in the number of local residents.

The historical 98 outside-area choice students are 75 in-district plus 23 out-of-district. Cross-enrollment inside the four areas is already included in the 415. The separate 23 placements have no residential breakdown here. The boundary change is already effective in 2026–27; no extra increment is added. The matrix’s historical 502 and proposal’s historical 503 are kept separate.

Even more math · Future uncertainty

Could residents alone fill the building?
Yes. Here is what it would take.

There is even more uncertainty farther into the future. 522 residents is a projection, not a ceiling. The alternative resident calculation holds that district projection fixed and considers attendance shifts after both school moves. The examples below also allow for more local residents.

These two combinations would each put resident children alone above the current Bear Creek building’s 492 stated places.

A Montessori-only attendance shift

More children live here than projected.

Assume 560 local residents, about 7% above BVSD’s 522, and keep the full Montessori-share shift used in the alternative resident calculation.

560local residents
88%approximately attend
≈ 493 resident children492 stated places

No outside-area choice students or placements are added. A higher resident count alone erases the remaining room under this attendance assumption.

Include a response to High Peaks moving

More local families choose to stay nearby.

Assume 545 residents, about 4% above BVSD’s 522, and add the historical High Peaks share as well as the Montessori share. About 90% then attend.

545local residents
90.4%approximately attend
≈ 493 resident children492 stated places

The matrix shows 12 local children at High Peaks. This scenario assumes the combined school attracts both focus-school shares after their moves. Again, no outside-area choice or placements are added.

Totals use exact historical shares before rounding: 442/502 and 454/502. The higher resident counts and full-share shifts are explicit scenario assumptions, not district forecasts or probability estimates.

The building could reach capacity before we add anyone from outside the neighborhood. What is the plan if that happens?

These are plausible combinations to plan for: the proposed school moves give families a reason to stay nearby, and the resident increases are small enough to matter in a building with so little room. The district should show its own uncertainty range and explain which assumptions keep our children’s school below capacity.

560 × 442/502 = 493.07; 545 × 454/502 = 492.89. Both exceed 492 before rounding. The hypothetical resident counts are 7.28% and 4.41% above the district’s projected 522. No outside-area students or placements are added. These are sensitivity examples without assigned probabilities, not forecasts.

Full shifts from the two focus schools are assumptions about future attendance shares, not a claim that the same historical children remain enrolled. A smaller shift or fewer residents would produce lower totals.

Will every grade
and program fit?

A place in the building is not the same as a workable class. The missing plan needs to show both.

The same 490-child benchmark, one grade at a time.

Advance today’s K–4 children by one grade and assume another kindergarten of 68. The comparison below divides each grade into either three or four evenly balanced classes. These are staffing scenarios, not the district’s announced class sizes.

Grade totals include all counted pupils. The district must reconcile general-education rosters, program membership and inclusion time before these can become actual class assignments.

Each number separated by a slash is one class. New kindergarten is assumed; the other grades carry forward the August 28, 2026 preliminary count. BVEA values are goals, not guaranteed caps. Sources and calculation.

The distribution matters.

With three classes in every grade, there would be 18 classes. Under this pupil-allocation assumption, second, third and fifth grade would each have a class above the BVEA goal. Meeting all grade-specific goals would require 21 classes: 3, 3, 4, 4, 3 and 4 from kindergarten through fifth grade.

That is a staffing and space question. It does not tell us that 21 suitable teaching spaces are available, or how dedicated program spaces and shared services fit around them.

What do we actually know about the rooms?

Staff now identify 20 classrooms in the capacity calculation.

On September 15, staff explained 20 × 24.58 = 491.6, rounded to 492. This is the building-capacity calculation, not a maximum class size. Staff also confirmed that RISE students are included in the enrollment projection; they should not be added again. 02:10:47 · recording; 02:11:38 · recording; 02:08:19 · recording.

The older contractor record describes an 18-classroom renovation, and BVSD’s February table lists 3.5 capacity rounds. These describe different things; the meeting supplies the current 20-classroom input. Renovation record, PDF p. 117 · February capacity table, p. 9.

Show families the aggregate capacity plan. How many suitable instructional spaces are available, and how many are needed for grade-level classes? How many additional spaces are needed for RISE, AIM, gifted and talented services, intervention, and small groups? How many acoustically separated teaching areas will be available, and what acoustic work is funded? No classroom locations or room-by-room building layout should be published.

Children

Grade and program rosters, with no child counted twice.

Teachers

Funded classes and clear triggers for adding staff.

Spaces

Usable rooms, quiet areas and a schedule that fits.

Will construction and the move fit the same calendar?

BVSD’s January 2026 bond update planned construction at the current Bear Creek building for summer 2027. Its March update made the next steps conditional on Board decisions. Which rooms will be ready when children arrive, and what is the funded backup plan if work runs late? Read the district’s updates.

Check the assumptions, staffing guidance and parent analysis

This comparison was prompted by another parent’s class-size analysis and rebuilt from district data. Their revised HTML now uses the same August 28 count and 490-child benchmark as this page. Their current class allocations still need confirmation. Three classes per grade remains a scenario here, not a verified district staffing commitment.

The FY2026–27 budget gives a guideline of one classroom teacher per 24.58 pupils, with adjustments for individual grades. That allocation formula is not a class-size cap. The BVEA agreement’s C-6 goals are 26 in K–1, 29 in grades 2–3 and 31 in grades 4–5. Program rosters and inclusion arrangements remain to be reconciled; no separate program pupils or assumed room deductions are added here.

A building can be below its stated capacity and still face a grade-level or program-space bottleneck. We have not applied a generic utilization discount to 492: the district needs to explain what its stated capacity already includes.

Questions for the Board

Our children and families
deserve a plan we can see.

Start by asking the Board:

What happens to the 45–98 students missing from the district’s projection?

That is the difference between the 490-child benchmark and the proposal’s 392–445 range. Staff have clarified that the projection excludes current Mesa outside-area open-enrollment students. Families still need to know how many can be accommodated and what assumptions produce the projected totals.

More questions families deserve answered before a vote

Families and Board members need time to read and digest concrete answers. The FAQs describe processes and later planning; we need the complete enrollment reconciliation and school-day plan.

  1. How does the building fit everyone?Next year’s simple benchmark is nearly at capacity. BVSD projects 522 local residents in 2030–31, more than the building’s 492 places, although not all residents will attend. What attendance, open-enrollment and placement assumptions produce its lower enrollment totals?
  2. Can the building support every class and program?How many suitable instructional and program spaces are available in aggregate, and how many are needed for grade-level classes, RISE, AIM, gifted and talented services, and small-group breakouts? Publish staffed-class counts, aggregate space counts, class-size triggers, and funding, without identifying specific room locations.
  3. What will a school day feel like?How will children learn in crowded, loud open classrooms? What guarantees cover maximum class size, building modifications and space without trailers? What is the earliest lunch time?
  4. What happens to Mesa’s preschool?Why weren’t preschool arrangements considered alongside the consolidation options, when including them could favor a different choice? The FAQ promises locations by October 1; families need to understand the implications before the vote.
  5. Will after-school care cover both communities?Will School Age Care (SAC) have at least as many places as the two current programs combined? The FAQ discusses investigating expansion; what capacity, space and staffing will actually be guaranteed?
  6. What protects both school communities?How will the district preserve friendships, trusted staff, routines and belonging for children from both current schools? What learning and well-being outcomes will it monitor, and what support is funded?
  7. What could change this decision?What evidence would lead the Board to reject or revise the consolidation? Which boundary, open-enrollment and program alternatives were compared, and why were they ruled out?
  8. What is the longer-term housing plan?Which enrollment projections include CU South, when would children arrive, and where would they attend? How will the plan adapt if more families move here than expected?

These are our children.
Show us the math. Show us their place in the plan.

About this analysis

The transparency our families deserve.

A proposal that affects so many students should make its steps, assumptions and calculations clear enough for families to check. The calculations above reconstruct the math and tradeoffs the proposal appears to imply; the district’s answers would let us test them.

In the spirit of full transparency: given the short time we have had access to the proposal, I used artificial intelligence tools to help analyze the relevant documents and prepare this site. I personally stand by the work and welcome corrections to any numbers or sources. I will update the analysis as additional information emerges.

I invite questions and corrections. Please email tdkautz@gmail.com. I would be very relieved to learn that I’ve made a mistake here. If I have, please point it out. Our children and families deserve that same openness from the district.

Updates

September 16, 2026 · Following the September 15 Board working session

The meeting clarified three points now reflected above:

  • The enrollment projection excludes all current Mesa open-enrollment students who live outside the proposed combined attendance area, including at the upper end of the range. 02:03:07 · recording; 02:08:48 · recording.
  • The placement rules differ. Mesa children inside the combined area have resident places. Those outside it receive application priority, without a guaranteed place. Current Bear Creek students can remain, including those open-enrolled there. Placement explanation and sources.
  • Staff explained the capacity calculation: 20 classrooms × 24.58 students, rounded to 492. They also confirmed that RISE students are included in the enrollment projection. Room discussion and sources.

The original calculations and “More room. More goodbyes.” conclusion remain.

BVSD projections changed between published reports

For the same target year, 2029-30, Mesa’s projected enrollment changed from 224 to 202, while Bear Creek’s changed from 272 to 310. These revisions illustrate that forecasts can change in both directions. They are forecasts for the separate schools, not realized enrollment changes or forecasts of the proposed combined school.

District enrollment archive, 2014–15 through 2025–26

The collection contains twelve October head-count years, 2014–15 through 2025–26. Across eleven combined K–4 to following-year grades 1–5 comparisons, the largest net decline is 21 pupils (3.9%), from 535 in 2019–20 to 514 in the 2020–21 pandemic school year. Aggregate counts measure net change, not individual retention, family decisions or the cause of departures. The smallest combined kindergarten in this record is 58. Step 2 uses the latest five complete years; the ten-year presentation series begins in 2016–17.

CDE Head Count Summaries, p. 1, Bear Creek and Mesa rows in all twelve years. The historical comparison excludes incoming kindergarten and graduating fifth grade and combines both schools to avoid counting transfers between them as departures. Scenario percentages divide net losses by the 422 current K–4 pupils. They hold incoming kindergarten at 68, or at the historical minimum of 58 as a sensitivity check, not a forecast.

2025–26 elementary enrollment-pattern matrix

Of 502 residents in the four areas, 415 attended the two current schools, 27 attended Montessori and 12 attended High Peaks. Applying all three shares to the projected 522 residents gives about 472 resident pupils, conditional on both full focus-school shares shifting, not a forecast. This is about 10 above the projected upper enrollment of 462 and 20 below capacity of 492. Alternatives model no shift, half of both shares, and Montessori alone. The 2025–26 schools also enrolled 98 outside-area choice students and 23 placements; these are not fixed cohorts added to the future. Residents-only capacity examples use hypothetical resident counts of 560 and 545.
