This graph displays the average daily attendance (ADA) for California's school districts. ADA is the total number of days of student attendance divided by the total number of days taught and is used for a variety of funding purposes. Generally, ADA is lower than enrollment due to such factors as transience, dropouts, and illness.

Note: Due to Covid-related school closures, the state did not collect apportionment ADA for 2020–21. Therefore, other than some small adjustments for LEAs experiencing growth, and a proxy ADA computation for newly operational charter schools, the 2020–21 ADA is the same as 2019–20. Learn more here.

Data collected by the California Department of Education (CDE) through the California Longitudinal Pupil Achievement Data System (CALPADS). ADA displayed in this graph is from the CDE School Fiscal Services Division's Current Expense of Education calculation.
