Principal Apportionment

The AB 602 Principal Apportionment includes revenue for the Base Grant Funding, Program Specialist/Regionalized Services, Low Incidence, Out-of-Home Care, and Extraordinary Cost Pool. This revenue is bundled as a single amount.

The Principal Apportionment is a series of apportionment calculations that adjust the flow of state funds throughout the fiscal year as information becomes known. The series are as follows:

  1. Advance Principal Apportionment is calculated by July 20 for payments from July through January. 
  2. First Principal Apportionment (P-1) is calculated by February 20 for payments from February through May.
  3. Second Principal Apportionment (P-2) is calculated by June 25 for the payment in June. 
  4. Annual Certification (Annual) is calculated by February of the the following year.  
  5. Annual First Recertification (R-1) is calculated by June 25 of the following year. 
  6. Annual Second Recertification (R-2) is calculated by February 20 of the second following year. 
  7. Annual Third Recertification (R-3) is calculated by June 20 of the second following year. 

Payments for the Advance, First, and Second Principal Apportionments occur from July through June of the fiscal year, and in a proportionate amount provided here.  

Payments for the Annual Certification and Recertifications occur as part of the "Adjustments and Prior Year Recomputations". See the following example for the 2022-23 Principal Apportionment: 

  • The Advance Principal Apportionment begins July, 2022
  • The First Principal Apportionment (P-1) is certified by February, 2023
  • The Second Principal Apportionment (P-2) is certified by July, 2023: This is used for the final SELPA allocation under the "Total Principal Apportionment". 
  • The Annual Certification (Annual) is certified by February, 2024
  • The Annual First Recertification (R-1) is certified by July, 2024: This is compared to P-2. The difference is the Adjustment.
  • The Annual Second Recertification (R-2) is certified by February, 2025
  • The Annual Third Recertification (R-3) is certified by July, 2025: This is compared to Annual R-1. The difference is the Adjustment.

Causes 

Changes to the allocation amounts may be due to several factors: 

  • Updates to the SELPA's special education property tax: If the SELPA's property tax amount increases, then the AB 602 net funding will decrease by the same amount. The same is true if the tax decreases, with a dollar-for-dollar change to the State AB 602 amount. 
  • Updates to CDE's proration factor: Although the SELPA funding is calculated based upon a rate, funding availability may cause a proration of its entitlement. If the proration factor is 0.98, the SELPA will receive 98% of its calculated entitlement. A change in the proration factor may cause an adjustment. Find more information here. 
  • Updates to LEA census data: AB 602 funding is calculated, in part, upon the SELPA's AB 602 average daily attendance (ADA). Any change in ADA may create an adjustment.
