AB 477 amends Education Code section 42238.02 to spell out new long‑term dollar targets for the Local Control Funding Formula (LCFF) base grants by grade span and to change a few related add‑ons and adjustments. The bill keeps the LCFF architecture—base, supplemental (20%), and concentration grants—but increases the explicit base grant targets for kindergarten–grade 12 beginning in the 2036–37 fiscal year and indexes annual changes to the Implicit Price Deflator for state and local government purchases.
For implementation, AB 477 preserves the CALPADS‑based unduplicated pupil counting rules and the three‑year rolling average used to compute the unduplicated percentage, retains the 10.4% K–3 add‑on (with tied class‑size conditions) and the 2.6% grades 9–12 add‑on, raises concentration grant rates (to 65% from 50% as of 2021–22), and sets new transitional kindergarten (TK) add‑on dollar amounts for two time periods. The bill also contains mechanics for preserving 2012–13 program funding as add‑ons and for enforcing audit and class‑size requirements.
At a Glance
What It Does
AB 477 establishes explicit LCFF base grant dollar targets for each grade span to take effect in 2036–37, ties annual base‑grant adjustments to the Implicit Price Deflator, and preserves supplemental and concentration add‑ons while increasing the concentration add‑on rate. It also maintains the K–3 10.4% add‑on and links receipt of that funding to class‑size progress and maintenance.
Who It Affects
All California school districts and charter schools (their LCFF entitlements and reporting); county offices of education (data validation duties); the State Superintendent and Controller (calculation, audits, and apportionment instructions); and entities operating TK programs (new add‑on rates).
Why It Matters
By fixing long‑term dollar targets and an indexation rule, the bill changes the state’s stated funding baseline for LCFF entitlements, which alters long‑range budget planning for districts and the state and affects how districts forecast resources available to meet local priorities.

What This Bill Actually Does
AB 477 revises the LCFF computation statute to specify concrete dollar targets for the base grant by grade span that become operative in the 2036–37 fiscal year. The statute continues to compute a grade‑span base, then applies statutory supplemental (20% of the base) and concentration add‑ons (the bill raises the applicable percentage as described elsewhere).
The base grants are subject to an annual adjustment tied to the Implicit Price Deflator for State and Local Government Purchases of Goods and Services, using specified May 10 data points to determine year‑to‑year percent change.
The bill preserves the existing unduplicated pupil counting approach: CALPADS submission of pupil‑level English learner, free/reduced meal, and foster youth data; county office validation duties; and a rolling three‑year average (with a 2013–14/2014–15 transitional rule) used to compute each LEA’s unduplicated percentage. AB 477 keeps the special rules that govern transferred, acquiring, divided, and restructured charter schools (including a provision that one acquiring‑charter rule lapses July 1, 2026 unless extended).For targeted historical and categorical funds, AB 477 carries forward add‑ons that effectively convert certain 2012–13 program allocations into LCFF add‑ons (Targeted Instructional Improvement Block Grant and various transportation allocations), capped at the 2012–13 amounts and subject to cost‑of‑living adjustments when specified.
The bill also establishes mechanics for calculating and apportioning TK add‑ons in two multi‑year phases, and keeps existing audit instructions and enforcement language—most notably the class‑size condition attached to the K–3 10.4% add‑on, which is not waivable by the State Board or the Superintendent.
The Five Things You Need to Know
The bill sets explicit LCFF base grant targets for 2036–37 of $14,879 (K–3), $15,104 (4–6), $15,551 (7–8), and $18,023 (9–12).
Annual base grant changes are indexed to the Implicit Price Deflator for State and Local Government Purchases, using May 10 data comparisons to calculate the percentage adjustment.
AB 477 preserves a K–3 add‑on equal to 10.4% of the adjusted K–3 base grant and conditions receipt on progress toward and maintenance of an average class enrollment of no more than 24 pupils per schoolsite (subject to collectively bargained alternatives).
The concentration grant rate for unduplicated pupils above the 55% threshold increases to 65% of the adjusted base grants beginning with the 2021–22 fiscal year (previously 50%).
Transitional kindergarten receives a TK add‑on of $2,813 per TK ADA for 2022–23 through 2035–36, and the bill replaces that amount with a larger add‑on beginning 2036–37 (the text lists $8,318 in that later period).
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Unduplicated pupil definition, CALPADS reporting, and three‑year rolling average
These provisions restate and lock in the operational definition of 'unduplicated pupil' (English learner, free/reduced‑price meal eligible, or foster youth) and require pupil‑level CALPADS submissions. County offices must validate aggregate counts and the Controller must include enforcement instructions in the audit guide. The Superintendent uses submitted CALPADS data and allows districts and charters to review and revise counts under specified timeframes; once data is no longer used in the current fiscal year calculation the data is final except for audit exceptions. Practically, this means accurate CALPADS reporting and audit readiness remain the gating factor for supplemental and concentration funding.
Grade‑span base grants and IPD indexing
AB 477 keeps the grade‑span base structure and inserts two layers: (1) explicit dollar targets for the base grants to be effective in 2036–37, and (2) an annual adjustment mechanism tied to the Implicit Price Deflator for State and Local Government Purchases of Goods and Services. The bill prescribes the exact data window and comparison dates (12‑month annual averages ending in the third quarter, with May 10 as the data cutoff) that the Superintendent and Department of Finance must use to calculate the percentage change, creating a predictable, formulaic annual index.
K–3 and 9–12 additional adjustments and class‑size conditions
The statute retains a K–3 additional adjustment equal to 10.4% of the adjusted base (and a 2.6% add‑on for 9–12). Receipt of the K–3 add‑on remains tied to progress toward and maintenance of average class enrollment targets (24 pupils per schoolsite), with an explicit exemption for districts that met the ratio in 2012–13 and a prohibition on State Board or Superintendent waivers. The provision also prescribes how districts calculate their progress metrics and the audit procedures the Controller must use to enforce compliance.
Supplemental and concentration grants (percentages and charter location rules)
The supplemental grant remains 20% of the adjusted base multiplied by the LEA’s unduplicated percentage. The concentration grant calculation is preserved but the bill specifies a higher percentage for the add‑on (65% of the adjusted base) for unduplicated pupils in excess of 55% beginning in 2021–22. For charter schools the statute caps the concentration‑eligible excess percentage to no more than the corresponding percentage of the host district (or the district with the highest percentage where the charter is in multiple districts) and requires reporting of physical location as part of the department’s determination—final as of the second principal apportionment.
Conversion of historical programs to add‑ons and TK/transportation mechanics
AB 477 transforms certain 2012–13 categorical allocations into fixed add‑ons: a TIIBG‑based add‑on capped at each LEA’s 2012–13 amount, and an add‑on equal to prior home‑to‑school transportation entitlements (or transferred entitlement from a JPAs). Both add‑ons are preserved as statutory components of the LCFF total and are subject to any specified cost‑of‑living adjustments in later years. The TK add‑on is specified in two phases: $2,813 per TK ADA through 2035–36, and a higher per‑ADA amount beginning 2036–37 (text lists a later‑period figure). The statute instructs the Superintendent how to compute and annually adjust those amounts.
Apportionment multiplication, property tax offsets, and pass‑through limits
The bill restates the standard apportionment math—multiplying rates by ADA or ADA equivalents—and then reduces the computed LCFF entitlement by various local revenue sources (property tax, specified redevelopment and special program receipts, etc.). It also preserves the obligation to transfer property‑tax in‑lieu funding to charter schools and contains a formula for when a district may redirect funding received on behalf of certain locally funded charter schools from 2012–13, tying that redirectable percentage to a historical computation rooted in local need fulfilled. Finally, the section confirms that revenue received under a specific Article XIII(b) constitutional subparagraph is excluded from certain excess tax/basic aid calculations.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- School districts with higher unduplicated pupil shares: The higher concentration add‑on rate (65% on unduplicated pupils above 55%) increases marginal revenue for districts serving high concentrations of disadvantaged pupils, widening the LCFF lift at the top end.
- All districts and charters in the long term: Explicit 2036–37 base grant targets and IPD indexation give districts a clear statutory funding benchmark for long‑range financial planning and for bargaining expectations tied to overall revenue availability.
- Transitional kindergarten programs and TK students: The statutory TK add‑on for TK ADA increases in the later phase, directing more per‑pupil dollars to TK operation (subject to the computation periods).
- County offices of education and CALPADS operators: The bill preserves and emphasizes CALPADS data submission and county validation duties, making accurate data systems and validation capacity more valuable and central to funding.
- Charter schools with lower unduplicated percentages located in low‑need districts: Because the concentration cap ties a charter’s eligible excess percentage to the host district’s percentage, some charters located in lower‑need districts may preserve access to concentration funding proportional to the local context.
Who Bears the Cost
- State budget and taxpayers: Specified dollar targets and indexation increase the state's long‑term funding obligations and reduce flexibility to prioritize competing budget demands unless offsetting revenues are provided.
- Local education agencies and bargaining units: Districts will face pressure to demonstrate how increased funding is used locally (including potential local expectations to increase educator compensation) while still meeting K–3 class‑size maintenance and other statutory conditions.
- County offices of education and the Department of Education: Increased validation, reporting, and audit responsibilities imply administrative costs and staffing needs to ensure CALPADS accuracy and to implement the audit guide instructions.
- Charter schools with high unduplicated pupil percentages in districts with lower percentages: The cap on concentration eligibility tied to host district percentages can reduce the concentration grant available to some charter schools compared to an uncapped calculation.
- School districts with redirected charter funding obligations: Districts that historically received and redirected certain 2012–13 charter funding may face new, formulaic limits on how much can be redirected under the bill’s historical computation.
Key Issues
The Core Tension
The bill balances two legitimate but conflicting interests: creating clear, statutory funding targets to anchor long‑term educator compensation and resource expectations versus preserving fiscal flexibility and realistic pay‑for‑play mechanisms. In short, AB 477 raises the baseline and codifies indexation to signal commitment, but it leaves open how and when the state will provide the revenue to match those targets and how local districts must choose between compliance obligations (e.g., class‑size maintenance, audit readiness) and competing uses of any new funds.
AB 477 sets aspirational, statute‑level dollar targets and locks in an annual index rule, but it does not itself create a dedicated revenue source tied to those larger 2036–37 base grants. That creates an implementation risk: the statute increases the state’s de jure funding baseline (and therefore local expectation) while the de facto realization of those amounts depends on future appropriations and budgetary choices.
The IPD indexing methodology provides predictability, but relying on the Implicit Price Deflator for State and Local Government Purchases concentrates indexation on a particular price series that can diverge from labor cost growth or school‑specific input inflation, which are material to educator compensation conversations.
Operationally, the statute’s heavy reliance on CALPADS and county validation means districts with weaker data systems may fail to capture unduplicated pupils and therefore lose supplemental/concentration funding. The bill also preserves rigid K–3 class‑size conditions (no waiver by the State Board or Superintendent) that could force trade‑offs between staffing, program choices, or bargaining outcomes.
Finally, there is drafting ambiguity in the TK add‑on language: the late‑period TK per‑ADA amount appears with overlapping numbers in the text, creating an immediate technical uncertainty the department will need to resolve administratively or the Legislature will need to correct.
