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.

Overview

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).

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.
