Principal Apportionment

Distribution of funds for local educational agencies (LEAs) in support of the public school system. Includes elementary school, high school and unified school districts; charter schools; and county offices of education.


The Principal Apportionment (PA) includes funding for the Local Control Funding Formula (LCFF), which is the primary source of an LEA's general purpose funding; Special Education (AB 602); Expanded Learning Opportunities Program; Arts and Music for Schools (Proposition 28); Equity Multiplier and funding for several other programs. In general, programs are included in the Principal Apportionment if they are state funded, on-going, driven by average daily attendance (ADA), or compatible with the Principal Apportionment data collection and payment schedule timelines.

The Principal Apportionment is a series of apportionment calculations that adjust the flow of state funds throughout the fiscal year as information becomes known pursuant to Education Code (EC) sections 41330, 41332, 41335, and 41336. For each fiscal year there are four apportionment certifications, the Advance Principal Apportionment, the First Principal Apportionment (P-1), the Second Principal Apportionment (P-2), and the Annual Apportionment (AN). (See Apportionments Tab for more information).


Principal Apportionment

Fiscal Year

At each fiscal year, the Principal Apportionment calculates and provide funding for the following apportionment certifications.

  • Advance Principal Apportionment
  • P-1 which supersedes Advance.
  • P-2 which supersedes P-1.
  • AN which supersedes P-2; Annual is recertified three times, First Annual Recertification (AN R1), Second Annual Recertification (AN R2), and Third Annual Recertification (AN R3), with LEAs reporting corrected data at specific times. Any data corrections are reflected with the subsequent years’ certifications.

Distribution of Funds

LEAs receive Principal Apportionment funds through a combination of local property taxes and state funds, with state funding composed of funds from the State School Fund and Education Protection Account (EPA). See the Principal Apportionment Payment Schedule for more information relating to the payments from the State School Fund. Local property tax revenues flow to LEAs at different times of the year based on statutory timelines and formulas. EPA payments are made quarterly at the end of September, December, March, and June (more information about EPA is available on the EPA web page).

The LCFF is hallmark legislation that fundamentally changed how all LEAs in the state are funded, how they are measured for results, and the services and supports they receive to allow all students to succeed to their greatest potential.

For school districts and charter schools, LCFF funding consists of grade span-specific base grants plus supplemental and concentration grants that are calculated based on student demographic factors. For county offices of education (COEs), LCFF funding consists of an amount for COE oversight activities and instructional programs. LCFF Entitlements are fulfilled by a combination of local property taxes and state aid from the Principal Apportionment and Education Protection Account (EPA).

School Districts

For most school districts, the largest source of revenue is the LCFF, which are unrestricted funds received through a combination of property taxes and state funds. State funds to school districts are paid through the Principal Apportionment and EPA.

Charter Schools

For most charter schools, the largest source of revenue is the LCFF, which are unrestricted funds received through a combination of in-lieu of property taxes and state funds. State funds to charter schools are paid through the Principal Apportionment and Education Protection Account. New and expanding charter schools may also receive funding through the Charter School Special Advance.

  • Charter School Funding
    Provides information about state general purpose and state and federal categorical funding to charter school authorizers and administrators.

County Offices of Education

A COE may operate various programs, as specified by applicable statutes, and enroll students residing in its own county or other counties within the State. County programs may be operated as COE schools, or as charter schools authorized by the COE pursuant to EC Section 47605.5.

LCFF funding is credited to either the COE (and/or the county program charter school), or the district of residence. This distinction is based on the type of student being served rather than the type of school or instructional setting.

Other PA Programs

Arts and Music in Schools (Prop 28)

The Arts and Music in Schools (AMS) funding program was established by Proposition 28 (2022). Funding is apportioned to school districts, county offices of education (COEs), and charter schools based on the share of statewide total enrollment and enrollment of economically disadvantaged pupils in the prior year. The purpose of AMS funds is to supplement arts education programs.

Expanded Learning Opportunities Program

Expanded Learning Opportunities Program funds are apportioned to school districts and charter schools based on prior year classroom-based ADA for grades transitional kindergarten/kindergarten through sixth grade and the prior year unduplicated pupil percentage as of the Second Principal Apportionment. The purpose of these funds is for after school and summer school enrichment programs as described in EC Section 46120.

Home to School Transportation Reimbursement

Home-to-School (HTS) Transportation Reimbursement funding was implemented by Assembly Bill (AB) 181 (Chapter 52, Statutes of 2022) and amended by AB 185 (Chapter 571, Statutes of 2022). It provides reimbursement funding for school districts and COEs based on the prior year eligible transportation expenditures and prior year LCFF transportation related add-on funding.

LCFF Equity Multiplier

The LCFF Equity Multiplier was implemented by Senate Bill (SB) 114 (Chapter 48, Statutes of 2023), and amended by SB 141 (Chapter 194, Statutes of 2023). It provides additional funding to LEAs for allocation to schoolsites meeting nonstability and socioeconomically disadvantaged pupil thresholds in the prior year, as reported in the California Department of Education’s Stability Rate Report. This funding must be used to provide evidence-based services and support for students at these schoolsites.

Special Education

Special education local plan areas (SELPAs) and LEAs receive various state funded special education programs through the Principal Apportionment. Funding details for these programs are available in the link below.

Frequently Asked Questions

The EPA provides LEAs with general purpose state aid funding pursuant to Section 36 of Article XIII of the California Constitution. The EPA funding is a component of an LEA's total LCFF entitlement as calculated in the Principal Apportionment.

The California Department of Education calculates EPA entitlements based on the statewide total of revenue limits and charter school block grant funding as calculated for the purpose of EPA. Each LEA's EPA entitlement is then reduced so that funding from local revenue and the EPA combined do not exceed the LEA's adjusted revenue limit or charter school general purpose funding, provided that each LEA receives the minimum EPA funding of $200 per unit of ADA. For most LEAs, EPA funding offsets LCFF state aid allocated through the Principal Apportionment.

EPA funds are allocated on a quarterly basis in September, December, March and June of each year.

User Assignment Resources

Effective fiscal year 2021–22, LEAs and SELPAs should have a PADC Administrator responsible for certifying Principal Apportionment data for the LEA/SELPA and all entities under its jurisdiction.

The assignment of the Administrator must be done by an oversight entity:

  • the California Department of Education (CDE) assigns an Administrator to each COE;
  • each COE assigns Administrators for school districts, charter schools under COE oversight, and SELPAs; each COE may assign additional Administrators for the COE itself;
  • each school district assigns Administrators for charter schools under district oversight.
