This is a single-day headcount — California's 2025-26 Census Day snapshot, not an ongoing enrollment feed. A campus missing from this list may still offer TK; our census match covers most but not all active campuses (no match here means "unknown," not "no TK"). And a school having TK doesn't guarantee it has an open seat for your child this year — enrollment isn't the same as availability. Call the school or check with the district to confirm.
