School Funding Projection · New School
Prepared August 24, 2026
Projected total program funding for Gran Vía as a CSI-authorized charter operating within Aurora Public Schools (Adams-Arapahoe 28J) boundaries, launching enrollment in FY 2027-28 under HB25-1320 and SB26-023. Every enrolled pupil is funded. FY27 is a pre-launch baseline at zero; funding begins in FY28.
01 · INPUTS & PROJECTION
Enrollment ramp, editable FY27-FY32 inputs matrix, gross and per-pupil projection with year-over-year change, and a breakdown of where the funding comes from in any selected year. FY27 is a pre-launch baseline at zero. FY28 (2027-28) is the funded launch year; the ramp runs through FY32.
Accounting district: Adams-Arapahoe 28J / Aurora Public Schools (0180) · Authorizer: CSI · CDE school code: pending (new school)
At-risk, ELL/MLL and SPED are entered as a percentage of total membership — 50% at-risk is measured against all 55 enrolled children at launch, and the resulting count is rounded to whole pupils (27.5 → 28). The figure beneath each cell is the weighted count that percentage produces: the rate applied to total membership. CDE counts every funding-eligible pupil once in the at-risk and ELL counts, the part-time codes included, so an HSE child is a whole body on the weights even though it is half a pupil on the base. The count is rounded to a whole pupil because a child is counted once and in full — CSI’s published PPR Estimates carry whole-integer at-risk, EL and SPED counts at every one of its schools.
FY27 base PPR is set at $8,900.40 (the appropriated rate). This input controls the assumed annual growth for FY28 onward, compounding through FY32. Default is 2.0% as a conservative planning baseline.
02 · TRAJECTORY
Gross total program from the FY28 launch through FY32. The dotted line shows the full new-formula value each year; the gap closes through the statewide HB25-1320 phase-in. FY27 is a $0 pre-launch baseline and is omitted from the chart.

03 · PLANNING IMPLICATIONS
Plain-language interpretation for Gran Vía’s board and founding team. Aurora Public Schools (28J) is a large, high-need urban district — its cost-of-living factor (0.229) and high at-risk share drive the projection, in contrast to the size- and locale-driven economics of small rural districts.
The CSI route funds all enrolled pupils. At launch, all 42.5 funded FTE generate the full formula, and every one of the 55 enrolled children carries a full demographic weight — an HSE pupil counts once, like any other, even though it is half a pupil on the base. Aurora’s 0.229 cost-of-living factor adds roughly 23% of base funding per pupil, and the 25% at-risk / ELL / SPED weights layer on top of a student body projected at 50% at-risk and 30% ELL at launch, rising to 65% and 35% by FY30.
The statewide phase-in runs in 15-point increments by fiscal year: FY28 opens at 45% new formula, then 60%, 75%, 90%, and 100% by FY32. Because Gran Vía launches in FY28, it never sees the FY27 30% step.
FY28 → FY32 trajectory under current inputs: — Bill benefit at full implementation (FY32 new-formula PPR vs full old-formula PPR): —As the accounting district, Adams-Arapahoe 28J sets the non-enrollment parameters — and as one of Colorado’s largest districts (38,617 funded count) its size factor is at the minimum (supplement 0) and its locale factor is 0. Gran Vía’s pupils do not move either. The small-district concentration factor does not trigger (it requires a district under 7,000 funded count). What carries the projection instead is the cost-of-living factor and the demographic weights.
Because funded pupils stay below 459, the old-formula leg funds at-risk at the flat 12% rate under §22-54-104(4)(b) — the above-average concentration band does not apply despite the 50%+ at-risk share.
Route: CSI-authorized · all pupils funded.This tool models total program funding under HB25-1320 / SB26-023. Not modeled: charter startup grants, federal and state non-formula revenue (Title I, IDEA, ELL grants), mill levy override sharing, facilities/capital construction, cash-flow timing, or authorization application costs and timelines. See Gran Vía’s board report and partnership models for capital and mill-levy detail.
COL factors beyond FY28 are held constant at the FY28 level (0.229). FY29–FY32 repeat the FY28 COL factor as an explicit assumption.
04 · METHODOLOGY & CAVEATS
The model implements the new-formula charter funding methodology established by HB25-1320 and the FY27-FY32 phase-in, with CDE’s FY28+ cost-of-living factors. District parameters are the Adams-Arapahoe 28J (0180) row of the CSF engine’s District Data tab.
Every figure in this tool belongs to one of four categories.
Set by enrolled bill text. Not adjustable.
Finalized administrative implementation of the charter funding formula.
From primary source files. Updates require new source publication.
User-adjustable. Defaults are school-supplied projections.
No prior-year actual total program exists. The FY28 launch-year hold-harmless floor does not apply and is shown as “not applicable” in the components view. Year-over-year change begins at FY29.
Base PPR × funded FTE, plus at-risk / ELL / SPED at 25% of base PPR per pupil, plus cost-of-living (0.23→0.229). Locale (0) and size (0) add nothing for 28J. Concentration factor does not trigger (district funded count 38,617 ≥ 7,000).
PP7 of $11,196.79 (Adams-Arapahoe 28J) × funded FTE, plus ELL at 8% × PP7, plus at-risk. Funded FTE is below 459, so at-risk funds at the flat 12% rate under §22-54-104(4)(b).
Statewide by fiscal year: FY27 30%, FY28 45%, FY29 60%, FY30 75%, FY31 90%, FY32 100% new formula. Gran Vía launches into the FY28 45% step.
FY28: not applicable (launch year, no prior-year baseline). FY29-FY31 floor = same-year old-formula leg × 1.01. FY32 has no statutory floor. School receives the greater of phase-in or floor.
Both legs follow the reconciled reading settled with CSI and CDE in August 2026. Multi-district online, P-Tech and TREP pupils are funded at their flat rates only: their FTE is netted out of the base and out of every factor base, and the at-risk, ELL and SPED counts are capped at the netted FTE (schools with no such pupils are unaffected). Concentration requires all three conditions — district under 7,000 funded, district above 70% at-risk, and this school above 70% at-risk. The $100,000 remote add-on and the district's actual rural funding are shared per pupil rather than paid per charter. On the 1994 leg the at-risk-at-average count is measured on membership, the result is the greater of the banded amount and the two flat 12% branches, and the state minimum runs on the netted count. These mechanics match the engine behind the CSF school-funding check.
Funded FTE = full-time pupils + 0.5 × HSE pupils, and drives base funding, the COL/locale/size factors and per-pupil revenue. The at-risk, ELL and SPED counts run on a different basis: they are headcounts of identified pupils, and a part-time pupil is counted once, in full. CDE’s 2026-27 At-Risk Count Audit Resource Guide defines the count as “the total number of students … reported as funding eligible,” and the ELL Count guide admits the part-time funding codes (82, 85, 94, 95) alongside the full-time ones. So the rate is struck on membership and applied to membership. Confirm the counted FTE and the supplement basis with the authorizer.
FY27 uses the older study (0.23); FY28 onward uses CDE’s rebased factor (0.229). No study exists beyond the FY28 biennium, so FY29-FY32 hold the FY28 factor constant — an explicit assumption.
