Summary:
Zip code 95448 has two public high schools in Healdsburg Unified, both serving grades 9–12: Healdsburg High enrolls 503 students, while Marce Becerra Academy enrolls 24. The clearest academic strength in the available results is Healdsburg High’s English and science performance, but its math results are a concern; the most striking difference between the schools is the Academy’s exceptionally high chronic absenteeism.
Healdsburg High stands out for English and science: in 2025–26, 65% of students were proficient in English language arts and 45% in science, respectively 15 and 9 percentage points above state results. Math was its weakest subject, at 26% proficient—13 points below the state and 22 below the district. The Academy stands out negatively for attendance: chronic absenteeism was 92%, versus 24% at Healdsburg High and 18% statewide. Graduation rates were a shared positive: 96% at Healdsburg High and 92% at the Academy, both above the state’s 88%. The Academy’s school-level test scores are suppressed, so the available results do not support a test-score ranking between the schools.
Healdsburg High’s academic results declined from 2024–25 to 2025–26 in all three subjects, while state results rose: the school’s English score fell from 69% to 65%, math from 37% to 26%, and science from 46% to 45%. SchoolDigger ranked it 689th of 2,137 schools in 2025–26, at the 68th percentile with 3 stars, down from the 81st percentile and 4 stars the prior year. The Academy’s rankings are older, so they are not a same-year comparison. For 2024–25, free/reduced lunch eligible students made up 57% at Healdsburg High and 79% at the Academy; student–teacher ratios were 17 and 12, respectively. These figures describe different school contexts, not causes of outcomes.
