Hidden Valley Elementary: More than half of kids exceed the standard. But 5th graders score lower than 3rd graders.
Hidden Valley is one of the strongest elementary schools in San Anselmo by raw achievement. The catch worth understanding: the cohort doesn't gain ground year-over-year.
Hidden Valley Elementary scores 74 of 100 on SchoolScope's Scope Score — the 93rd percentile of 5,230 California elementary schools (CDE CAASPP 2025).

The headline number: 50.5% of students scored in the top band on the state test. The California average is 21.6%.

The school, grade by grade
ELA · CAASPP 2024–25Different students, same year — each bar is one grade's proficiency mix.
The honest read: the share exceeding rises 9.4pp across grades; the floor rises 6.0pp. The state average rises 4.5pp over the same span. The ceiling holds — more kids exceed by grade 5 — but the floor slips: fewer clear the bar at all. A school visit and conversation with teachers will tell you more than this number.
