Statewide Student Identifier (SSID)
A Statewide Student Identifier (SSID) is a unique, non-personally-identifiable number linked to a given individual student within the California public K–12 educational system. SSIDs are used to maintain data on individual students, such as linking students to statewide assessment scores and tracking students in and out of schools and LEAs in order to determine more accurate dropout and graduation rates.
All public California K–12 local educational agencies (LEAs), including charter schools, are required to obtain SSIDs through the California Longitudinal Pupil Achievement Data System (CALPADS) for students in kindergarten through grade 12. These agencies should maintain the SSIDs in their local systems as well as in CALPADS.
Maintaining SSIDs includes providing updates to changes in students’ enrollment statuses, and it includes the submission of enrollment and exit data to CALPADS. LEA staff can find more information about SSIDs in the Statewide Student Identifier (SSID) and Enrollment Procedures document, which is located on the CALPADS System Documentation Web page.
