A growth engine — students gain measurably more here than at peer schools.
Composite scores are SchoolScope's analysis of public data from the California Dept. of Education (CAASPP, chronic absenteeism, suspension rates). They are not official CDE ratings and should not be the sole basis for school decisions. See methodology.

Most rating sites report "54% proficient" for Westborough Middle and stop there. Here's what that number hides:
24.1% of students exceeded standard while 30.1% met it. That exceeded rate is 6.8 points above the state average of 17.3%. That's 3.5 points above the South San Francisco Unified district average of 20.6%. Compared to the 4 nearby schools within ~3 miles, this exceeded rate is 6.0 points higher (vs 18.1% average). The gap between "met" and "exceeded" can reveal how much a school's curriculum challenges students beyond proficiency.
Students here improve by 6.5 percentage points from Grade 6 to grade 8 growth, suggesting the school is adding value beyond what students arrive with.
California's Dashboard shows ELA performance increased and Math declined year-over-year. 20.7% of English learners reached Level 4 (Well Developed) on ELPAC.
Chronic absenteeism is 9.3%, better than the state average of 19.3%.
