School Funding Projection · New School
Prepared July 2, 2026 — CSI-authorized (APS boundary) route, all pupils funded. Reflects CDE’s “< 459” at-risk clarification.
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 — the structural gap of the current ER BOCES route closes. FY27 is a pre-launch baseline at zero; funding begins in FY28.
01 · INPUTS & PROJECTION
Enrollment ramp, editable FY27-FY32 inputs matrix, gross-net-PPR 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 · 3% retention · CDE school code: pending (new school)
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 (0.23) and high at-risk share drive the projection, in contrast to the size- and locale-driven economics of small rural districts.
The decisive difference from Gran Vía’s current ER BOCES authorization is that the CSI route funds all enrolled pupils, not a fixed 13. At launch, 42.5 funded FTE generate the full formula rather than leaving 17+ pupils unfunded. Aurora’s 0.23 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 50% at-risk, 30% ELL student body.
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 (3% retention) · all pupils funded.This tool models total program funding under HB25-1320 / SB26-023. Not modeled: the ER BOCES fallback route (13 funded pupils), 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 the ER BOCES comparison and capital/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.
Funded FTE = full-time pupils + 0.5 × HSE pupils. Demographic supplement counts scale on the funded FTE basis. Confirm counted FTE and 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.
CSI-authorized charters: 3% (§22-30.5-513). The ER BOCES and district-authorized routes are out of scope for this projection.
