Summary
Alianza Charter is a K–8 school in Watsonville, California, serving 626 students in Pajaro Valley Unified, and it has the largest enrollment among 11 nearby schools. Its academic results are mixed: in 2025–2026, it scored above the district in English language arts (ELA) and math, but below the state in ELA, math and science. The most important takeaway is that being ahead of the district in two subjects has not yet translated into state-level results.
ELA is Alianza’s strongest all-grade result against the district, while science is its weakest against the state. ELA proficiency was 36%, 8 points above the district but 14 points below the state; math was 24%, 6 points above the district but 14 points below the state. Science was 18%, 1 point below the district and 18 points below the state. Alianza also trailed both nearby K–8 schools, Linscott Charter and Watsonville Charter School of the Arts, in all three all-grade subjects. Results vary by grade: sixth-grade ELA reached 52%, above the state’s 48%, while eighth-grade ELA was 24%, 26 points below the state. Eighth-grade math and science were also low, at 15% and 7%.
Core results have not improved steadily over the four reported years: ELA was down 1 percentage point overall, math down 2 and science down 3, while the gaps with the state widened in each subject. SchoolDigger ranked Alianza at the 34th percentile with 2 stars in 2025–2026, third-highest among nearby schools, though its percentile fell 12 points from the prior year. SchoolDigger’s statewide ranking for how well the school serves English language learner students dropped from the 71st percentile in 2022–2023 to the 52nd in 2023–2024; its overall percentile rose from 41 to 45 over those years. The 2024–2025 student-teacher ratio was 22.3, close to the nearby-school average of 22.2. In 2024–2025, 80% of students were free/reduced lunch eligible, lower than 8 of 10 nearby schools; this eligibility measure does not say whether students receive free meals.
