How often should the homeless data be updated in California Longitudinal Pupil Achievement Data System (CALPADS)?

CALPADS needs to be updated on Census Day (First Wednesday in October) and at least once in the academic year (if the student was not homeless on Census Day, but was homeless sometime in the academic year). Although not required, local education agency (LEAs) are strongly encouraged to regularly update data in CALPADS throughout the academic year to ensure youth are correctly identified as homeless.

When are homeless data collected in CALPADS?

Homeless data are collected continually throughout the school year and are certified twice a year: once during Fall 1 certification window and once during the End of Year 3 (EOY3) certification window. LEAs are strongly encouraged to regularly update data in CALPADS throughout the academic year to ensure youth are correctly identified as homeless. Refer to the CALPADS Calendar for submission windows and certification deadlines.

What should I do with preschool 0-5 age data?

LEAs should submit a homeless program record for infant, toddler, and pre-K children who are enrolled in CALPADS and who are homeless, as these students are included in all homeless reports in CALPADS. For more information refer to the CALPADS Data Guide (DOCX; Dated 14-Feb-2020).

What is the difference between CALPADS and Consolidated Application and Reporting System CARS?

The CARS is a data collection system to apply for Categorical Program Funding and to report on the use of those funds. CALPADS collects homeless enrollment information. CALPADS is a data reporting system through which LEAs report specific data used to determine Local Control Funding Formula (LCFF) funding allocations and to calculate educational outcomes.
