Sequoia Union High

The Sequoia Union High area includes six high schools serving grades 9–12, with 8,419 students total and enrollments ranging from 175 to 2,360. In 2025–2026, the schools’ average proficiency rates were 59% in English Language Arts (ELA), 41% in Mathematics, and 46% in Science, compared with California rates of 49%, 38%, and 36%. The averages are above state rates in all three subjects, but they hide very large differences from one school to another—the most important finding for families comparing schools.

Carlmont High leads in every subject, with 87% proficient in ELA, 75% in Mathematics, and 75% in Science; those results are 18, 22, and 22 percentage points above the next-highest schools in each subject. At the other end, Redwood High has 12% proficiency in ELA and 0% in Mathematics and Science. Its results trail the next-lowest school by 45 points in ELA, 37 in Mathematics, and 42 in Science. SchoolDigger ranks Carlmont 38th of 2,137 California schools, in the 98th percentile, and Redwood 2,077th, in the 3rd percentile. The middle varies by subject: Menlo-Atherton High is second in ELA and Mathematics, while Woodside High is second in Science.

Group averages improved from 2024–2025 to 2025–2026 by 3 percentage points in ELA, 5 in Mathematics, and 7 in Science, though individual schools did not all improve. Tide Academy made particularly strong gains—16 points in Mathematics and 19 in Science—while Redwood remained low and fell 3 points in Science. Reported free/reduced lunch eligible shares for 2024–2025 range from 9% at Carlmont to 63% at Redwood; Tide and Sequoia High report similar shares, 40% and 39%, but differ in results. The smallest schools also differ sharply: Tide enrolls 212 students and has a 9.4:1 student-teacher ratio, while Redwood enrolls 175 and has a 21.7:1 ratio. These measures offer context, not an explanation for school results.
