Summary:
ZIP code 94804 has two middle schools serving grades 6–8: Richmond Charter Academy, with 296 students, and Manzanita Middle, with 92. In 2025–2026, Richmond had higher proficiency than Manzanita in English language arts (ELA), math and science, but neither school reached the state level in any of the three subjects. The clearest overall takeaway is that Richmond leads locally, while both schools remain below state results—especially in math.
Richmond Charter Academy stands out as the stronger of the two: its proficiency was 43% in ELA, 17% in math and 23% in science, compared with 15%, 8% and 10% at Manzanita Middle. Richmond’s leads were 28 percentage points in ELA, 9 in math and 12 in science. It was also closer to the state in every subject: 7 points below in ELA, 21 in math and 13 in science, while Manzanita was 35, 30 and 26 points below. SchoolDigger ranks Richmond 1,786 of 2,703 schools (34th percentile, 2 stars) and Manzanita 2,611 of 2,703 (3rd percentile, 0 stars). Richmond’s strongest grade-specific result was eighth-grade ELA at 45%, 5 points below the state; both schools were well below the state in math at every grade.
Recent results show different directions by subject. From 2024–2025 to 2025–2026, Richmond’s science proficiency rose 9 points, while its ELA and math results fell by 4 and 1 points; Manzanita’s science rose by less than 1 point, while its ELA and math fell by 15 and 5 points. Across the two schools, the average shortfall from the state widened by 10 points in ELA and 4 in math, but narrowed by 1 in science. Other context differs too: Richmond’s 2024–2025 student-teacher ratio was 36.7, compared with 23.0 at Manzanita. Both reported free/reduced lunch eligible for 2024–2025: 82% at Richmond and 86% at Manzanita. These figures describe differences between the schools, but do not establish what explains the achievement results.
