*Please note: The Cohort data pull will occur on August 16, 2027.

**The data that local educational agencies (LEAs) approve on CALPADS Report 1.17 – LCFF – Count in the Fall 1 submission are used to determine the Unduplicated Pupil Count (UPC), the basis for determining the unduplicated pupil percentage (UPP), which determines 2026–27 Local Control Funding Formula (LCFF) supplemental and concentration grant funding. Data on this report approved by the December 11, 2026 Certification Deadline will be used in the calculation of the First Principal Apportionment (P1). Data on this report approved by the January 22, 2027 Amendment Window Deadline will be used in the calculation of the Second Principal Apportionment (P2). Any changes after this date must be made through the local audit process.

Special Education Local Plan Area (SELPA) approval is not required but is strongly encouraged by the December 11, 2026 Fall 1 Certification Deadline.

Annually, as part of the Compliance Improvement Monitoring (CIM) for the Individuals with Disabilities Education Act (IDEA), the California Department of Education's (CDE's) Special Education Division is required to issue monitoring determinations for LEAs using a combination of prior year End-of-Year data and current-year Fall 1 data. In order for Annual Determination Letters to be issued earlier to give LEAs more time to complete CIM activities, the data used to calculate federal Indicator 9 (Disproportionality overall), and Indicator 10 (Disproportionality by specific disability categories) will be pulled from CALPADS following the December 11, 2026 Certification Deadline, rather than after the close of the Amendment Window. The data used for these determinations will therefore include data approved by the LEA only, or if the SELPA approves by the Certification Deadline, data which have been approved by both the LEA and SELPA.
