Submit P‑1 Attendance and Related PADC Data

A broad first-principal-apportionment close that reconciles attendance, AICF, charter location, infant funding, necessary-small-school, SELPA allocation, special-education tax, and alternative-rate data.

  • Principal Apportionment
  • PADC
  • P‑1
Date(s)January 15, 2027
Applies toLEAs, charters, COEs, SELPAs, and local-revenue entities with applicable P‑1 screens

In Plain Language: Inventory every applicable January 15 screen, reconcile each to its authoritative attendance, program, location, tax, or fiscal source, and complete the required approvals in PADC.

Why this matters

P‑1 converts operational data into current-year funding estimates. A complete attendance screen does not prove the related charter, SELPA, infant, AICF, or tax screens are complete.

Primary ownership

Primary owner: principal-apportionment/PADC coordinator. Partners: attendance, charter, COE, SELPA, special education, infant/AICF, necessary-small-school, local revenue, fiscal, and certifiers.

From applicable screens to certified P-1 data: the SDLA ITO workflow

Each January 15 screen reconciles to its own authoritative source before cross-screen review. This SDLA ITO (Input, Transformation, Output) graphic shows how the entity-specific screen list, and attendance, program, location, tax, and fiscal sources become the applicability matrix, the calculations and PADC reports, and the certification package.

SDLA ITO: eleven steps from the entity-specific screen list, and attendance, program, location, tax, and fiscal sources, through an applicability matrix, source close, PADC entry, and cross-screen review, to the applicability matrix, the calculations and PADC reports, and the certification package.
Read down each column, then move to the next: Input identifies what to collect; Transformation covers an applicability matrix, source close, PADC entry, and cross-screen review; Output covers the applicability matrix, the calculations and PADC reports, and the certification package. Complete approvals and certifications by January 15, 2027.
