How California Public Schools Are Funded
A plain-language introduction to average daily attendance, California’s Local Control Funding Formula, supplemental state and federal resources, and the reasons spending differs among school districts.
The short explanation
California public schools do not receive one identical amount for every enrolled student. Most ongoing general-purpose funding for school districts and charter schools flows through the Local Control Funding Formula. The formula begins with grade-based funding, uses attendance in its calculation, and provides additional resources based on student needs. Schools may also receive restricted state and federal grants, local revenue, and one-time allocations.
Funding, revenue, and spending are different
A funding formula determines an entitlement. Revenue describes money received from different sources. Spending describes the costs recorded during a period. A per-pupil number may use enrollment, attendance, or another denominator, so two figures with the same label may not be directly comparable.
Where the money comes from
LCFF funding
The main state funding system combines local property-tax revenue with state aid. It includes grade-span base grants and, when applicable, supplemental and concentration grants, adjustments, and add-ons.
Other state funding
California also provides funding outside the main LCFF entitlement for specified programs or purposes. Some allocations are ongoing; others are one-time and carry separate eligibility, spending, and reporting rules.
Federal funding
Federal programs such as Title I, Title II, Title III, Title IV, IDEA, child nutrition, and Perkins generally support defined populations or purposes. These funds commonly carry program, fiscal, documentation, and monitoring requirements.
Local and other revenue
Districts may receive parcel-tax revenue, facility funds, donations, interest, fees, local grants, and other resources. The availability of these sources varies considerably by community and by district.
How the Local Control Funding Formula works
- Base grants: The formula begins with a rate for each grade span and multiplies applicable rates by funded ADA. Kindergarten through grade three and grades nine through twelve receive grade-span adjustments.
- Supplemental grant: Additional funding is calculated using 20 percent of the adjusted base grant, ADA, and the LEA’s unduplicated pupil percentage.
- Concentration grant: Additional funding is calculated for the portion of an LEA’s unduplicated pupil percentage above 55 percent, using a 65 percent factor.
- Adjustments and add-ons: Depending on the LEA, the calculation may include necessary small school funding, transitional kindergarten funding, transportation or historical add-ons, and other statutory adjustments.
- Funding sources: Local property taxes are counted toward the entitlement. State aid generally supplies the balance, subject to the applicable formula and guarantee provisions.
The “unduplicated” pupil count includes students who are English learners, meet income eligibility criteria for free or reduced-price meals, are foster youth, or fall into more than one of those groups. A student is counted once even when the student meets multiple criteria.
What is average daily attendance?
Average daily attendance, or ADA, is the total number of days of student attendance divided by the number of instructional days. It is not the same as enrollment.
A simplified example
If 1,000 students are enrolled but an average of 940 attend each instructional day, the simplified ADA is approximately 940—not 1,000.
Why it matters
Attendance affects school funding and is also an educational concern. California now uses statutory attendance protections and averaging rules in parts of the LCFF calculation, so funded ADA is not always identical to the current year’s observed ADA.
What “supplemental” funding means
| Funding | Plain-language meaning | Important limitation |
|---|---|---|
| LCFF base funding | The central grade-span funding used to support the general educational program. | The rate is per funded ADA, not simply per student enrolled. |
| LCFF supplemental grant | Additional state funding calculated from the unduplicated percentage of English learners, income-eligible students, and foster youth. | The LEA must use increased or improved services requirements when planning these resources. |
| LCFF concentration grant | Additional state funding for LEAs whose unduplicated pupil percentage exceeds 55 percent. | Only the portion above the statutory threshold is used in this calculation. |
| Other state categorical funding | Money appropriated for a particular program, service, population, or policy objective. | Rules vary by appropriation; “state-funded” does not automatically mean unrestricted. |
| Federal program funding | Federal assistance awarded for defined programs and populations. | Federal funds usually supplement the educational program and carry separate allowability, documentation, and monitoring requirements. |
The word supplemental is used in more than one context. The LCFF Supplemental Grant is a specific California formula component. A federal requirement that funds “supplement, not supplant” is a separate legal and fiscal concept.
How much do California districts spend per pupil?
There is no single universally correct “per-pupil spending” number. For a consistent district comparison, this page uses CDE’s 2024–25 Current Expense of Education per ADA. The measure includes specified General Fund salaries, benefits, books, supplies, equipment replacement, services, and indirect costs, then removes certain activities such as facilities acquisition and construction, food services, and community services.
| 2024–25 measure | Amount per ADA | How to interpret it |
|---|---|---|
| Statewide current expense | $21,214 | Total included statewide expense divided by statewide current-expense ADA |
| Middle 80 percent of district records | Approximately $15,872–$31,906 | Ten percent of district records fall below this range and ten percent fall above it |
| Full observed district-record range | Approximately $11,404–$356,868 | The extreme high value belongs to a district reporting only 17.83 ADA and is not a typical comparison |
Why show the middle 80 percent?
California includes very small, remote, and specialized districts. Their fixed costs are divided among very few units of ADA, which can produce extraordinary per-ADA amounts. The full range is real, but the middle 80 percent gives families and new staff a more useful picture of ordinary variation.
SDLA calculated the distribution from all 932 records in CDE’s district worksheet. The statewide figure is CDE’s weighted statewide calculation. Amounts are rounded to the nearest dollar. The workbook is dated January 29, 2026.
Why district spending differs
Student needs and programs
Districts serve different concentrations of English learners, students from low-income households, foster youth, students with disabilities, and other populations requiring additional services.
Size and geography
Small and remote districts must provide leadership, facilities, transportation, and core services even when those fixed costs are spread across very few students.
Labor and operating costs
Salary schedules, benefit costs, regional labor markets, transportation, utilities, insurance, and contracted services differ among communities.
Funding mix and timing
Restricted grants, local revenue, prior-year carryover, one-time appropriations, declining enrollment protections, and capital projects can affect reported amounts and year-to-year comparisons.
Questions to ask when comparing districts
- Does the figure use enrollment, actual ADA, or funded ADA?
- Does it describe revenue, current operating expense, total expenditures, or an adopted budget?
- Are facilities, debt, food service, retirement-system contributions, or one-time grants included?
- Are the districts similar in size, grade configuration, geography, student needs, and services provided?
- Does the comparison use the same fiscal year and the same accounting definition?
- Is an unusual value caused by a genuine service difference, a one-time event, or a very small denominator?
Spending alone does not measure school quality
A higher per-pupil figure does not automatically mean stronger services or better outcomes, and a lower figure does not by itself prove efficiency. Financial data should be considered with student needs, program design, staffing, outcomes, reserves, facilities, and local operating conditions.
