Summary:
The five schools in Contra Costa County Office of Education are a specialized mix of alternative programs and high schools, serving grades K–12, 6–12 and 7–12, with enrollments from 15 to 116. Among the two schools with numeric 2025–2026 test scores, average proficiency was 5% in English language arts (ELA), 0% in math and 6% in science, compared with state results of 49%, 38% and 36%—gaps of 44, 38 and 30 points; the clearest finding is that both reporting schools were well below state proficiency in every tested subject.
Floyd I. Marchus leads the schools with reported scores: its ELA result was 10%, versus 0% at Golden Gate Community, and its science result was 13% versus 0%; both scored 0% in math. Golden Gate also stands out for other reported outcomes: its 38% graduation rate was 50 points below the state, its 50% dropout rate was 42 points above, and its 68% chronic absenteeism was 50 points above the state. Mt. McKinley had the highest reported graduation rate, at 50%, but that was still 38 points below the state. Its latest test scores are not available as numeric results.
Recent test-score changes are mixed: from 2024–2025 to 2025–2026, Floyd improved by 2 points in ELA and 1 point in science, while Golden Gate fell by 10 points in ELA and 4 in science; math stayed at 0% at both schools. Across the two, average ELA and science results declined as state scores rose. Other differences may help families compare these distinct programs: in 2024–2025, free/reduced lunch eligible shares were 60% at Floyd and 81% at Golden Gate, while student–teacher ratios were 6.2 and 9.7, respectively. SchoolDigger ranked Golden Gate at the 3rd, 5th and 1st percentiles in 2023–2024, 2024–2025 and 2025–2026, respectively. These comparisons describe a small, varied group; three schools have no numeric latest test scores.
