Chapter 2: Understanding CALPADS and Why It Matters Now

What CALPADS Is

CALPADS — the California Longitudinal Pupil Achievement Data System — is the state’s centralized data repository for K-12 student information. Launched in phases starting in 2008-09, it tracks everything from enrollment and demographics to course completion, special education services, and assessment results. For most of its existence, CALPADS has been the domain of district data coordinators and registrars. Afterschool program leaders rarely needed to engage with it.

That changed on September 30, 2024, when Governor Newsom signed Assembly Bill 1113 into law.

The 2025-26 Shift: New Mandatory Reporting for Expanded Learning Programs

AB 1113 requires the California Department of Education to collect data on students enrolled in afterschool programs, bringing expanded learning into CALPADS for the first time. Starting in the 2025-26 school year, all Local Educational Agencies (LEAs) receiving funding for the following programs must submit expanded learning data to CALPADS:

Expanded Learning Opportunities Program (ELO-P)
After School Education and Safety Program (ASES)
21st Century Community Learning Centers Program (21st CCLC), including the After School Safety and Enrichment for Teens (ASSETS) program

As detailed in CALPADS Update Flash #305, LEAs participating in these programs must collect data during the 2025-26 fiscal year and upload it as part of the 2025-26 CALPADS End-of-Year (EOY) submission cycle opening in May 2026. The compliance timeline started much earlier — in Fall 2025, when districts needed to build the systems and workflows that produce clean data by spring.

Running parallel to AB 1113 is Senate Bill 153 (Chapter 38, Statutes of 2024), as amended by SB 176 (Chapter 998, Statutes of 2024). These bills established California’s Attendance Recovery (AR) program, an optional program for students in grades TK-12. AR doesn’t change a student’s attendance record — they were absent and stay absent. What it does is let districts recover ADA apportionment for those days, turning previously unrecoverable absences into fiscal credit. AR intersects with CALPADS reporting because AR data must be submitted through the Student Absence Summary (STAS) file. We’ll cover AR in depth in a separate chapter.

Why This Affects Your Afterschool Program

If you operate any program funded by ELO-P, ASES, or 21st CCLC grants, you’re now subject to mandatory CALPADS reporting. This isn’t optional. CDE has made clear that LEAs with expanded learning programs will receive a fatal Certification Validation Rule (CVR) error if they fail to submit LEAP records. “Fatal” means your submission can’t be certified until the error is resolved.

The funding implications don’t come from CALPADS directly — ADA calculations happen through a separate process called Principal Apportionment Data Collection (PADC). But falling behind on CALPADS triggers a series of downstream consequences:

Technical Assistance: Under Education Code Section 52071, as amended by SB 114, county superintendents must provide technical assistance to any district that fails to meet the data submission requirements of EC Section 60900. This means reviews of your data collection policies, submission procedures, and SIS oversight.
Differentiated Assistance: Districts and County Offices of Education that miss CALPADS certification deadlines for Fall 1, Fall 2, or End-of-Year submissions may be identified for CALPADS Differentiated Assistance — a formal support and monitoring process requiring additional reporting and documentation.
Delayed Funding Calculations: CALPADS data feeds into Principal Apportionment timelines. The Fall 1 Certification Deadline (December 12, 2025) drove P1 calculations. The Fall 1 Amendment Window (closed January 23, 2026) drove P2. Both windows have closed — any corrections now require the local audit process. Looking ahead, the EOY submission opening in May 2026 is the critical window for expanded learning data.
Federal Funding Risks: Late or missing CALPADS submissions can affect eligibility for federal funding streams that rely on timely state data reporting.
LCFF Grant Impacts: The data LEAs approve on CALPADS Report 1.17 — LCFF Count in the Fall 1 submission determines the Unduplicated Pupil Count (UPC), which directly affects Local Control Funding Formula supplemental and concentration grant allocations for the following fiscal year.

CALPADS compliance matters. Not because it directly determines your afterschool program’s grant funding (that still happens through CDE’s Expanded Learning Division), but because it’s tied into state accountability and funding systems that affect everything else.

The Dual Reporting Burden: PADC vs. CALPADS

CALPADS doesn’t replace other reporting requirements — it adds to them. Districts still submit attendance and enrollment data through PADC for fiscal apportionment. CALPADS serves a different function: longitudinal tracking for accountability, chronic absenteeism calculations, and program participation monitoring.

This creates a dual reporting burden. You’ll track student attendance for grant compliance (ASES, ELO-P, or 21st CCLC requirements), submit fiscal data through PADC (for ADA calculations), and now report participation data through CALPADS (for state accountability). The good news: these data elements largely overlap. If you’re tracking daily attendance accurately for one system, you have what you need for the others. The challenge is making sure data flows correctly into all three reporting streams without manual re-entry or transformation errors.

Timeline Pressure: Key Submission Windows

CALPADS operates on a structured calendar tied to the state’s fiscal apportionment cycle. Here’s where the 2025-26 timeline stands:

December 12, 2025 (completed): Fall 1 Certification Deadline. Data approved by this date was used to calculate the First Principal Apportionment (P1).
January 23, 2026 (completed): Fall 1 Amendment Window Deadline. Data approved by this date was used for the Second Principal Apportionment (P2). Changes after this date require the local audit process.
May 2026 (upcoming): End-of-Year submission cycle opens. LEAs submit LEAP files with expanded learning participation data covering the full academic year (July 1, 2025 – June 30, 2026). This is your critical deadline for expanded learning data.
Late 2026: CDE will publish the alternate chronic absenteeism rate, which incorporates attendance accrued through Attendance Recovery programs.

The Fall 2 deadline (typically late February) applies primarily to other data elements. Check the CALPADS submission calendar at the CDE CALPADS page for the latest dates and any updates to submission timelines.

These deadlines don’t bend. As CALPADS Update Flash #259 states: “There will no longer be deadline extensions for End-of-Year submissions.” CDE expects LEAs to build the capacity and systems needed to meet deadlines without exception.

The Bottom Line

CALPADS reporting for expanded learning programs changes what the state expects from you. For the first time, afterschool participation data will live in the same longitudinal system that monitors student achievement, graduation rates, and chronic absenteeism. That opens doors — afterschool data feeding into student support planning — but it demands cross-departmental coordination and data quality that most afterschool operations haven’t needed before.

The rest of this chapter walks through the specific requirements, technical challenges, and practical strategies for building CALPADS compliance workflows that last. Whether you’re a district with deep data infrastructure or a small LEA managing expanded learning with limited IT support, the goal is the same: submit clean, accurate data on time, every time.
