Each campus’s TK headcount is from the state’s 2025–26 October enrollment count. Each Scope Score and percentile compares a school’s elementary grades with California elementary schools. A campus without elementary results shows none.
Each headcount counts the students enrolled on one October day, so it shows who enrolled, not seats open now. A campus missing here may still run TK; confirm with the school or district.
