Summary:
ZIP code 95987 has six schools: Williams Primary Elementary (K–3), Williams Upper Elementary (grades 4–6), Williams Junior/Senior High and S. William Abel Academy (grades 7–12), Mid Valley High (Continuation) (grades 10–12), and Coastal Buttes Academy (K–12). Results vary by school and subject, and the strongest school in one subject is not necessarily the strongest in another. Most importantly, no school with reported all-grades proficiency results reaches the state rate, and math has the widest spread between schools.
In 2025–2026, Williams Primary Elementary had the highest reported all-grades math result, at 30% proficient; Abel Academy had 0%, a 30-point difference, and Primary was still 9 points below the state’s 38%. Williams Junior/Senior High led in English, with 31% compared with Abel’s 20%; both were below the state’s 49%. Williams Upper Elementary had the highest reported science result, 15%, versus 7% at Junior/Senior High; both were below the state’s 36%. These all-grades comparisons cover different grade mixes, and results for Mid Valley and Coastal Buttes are suppressed or not provided.
Recent changes are mixed: the equal-school English average fell from 29% to 26% between 2024–2025 and 2025–2026, math stayed about 12%, and science rose from 9% to 11%, while statewide results rose in all three subjects. Upper Elementary improved in all three reported subjects; Primary’s math rose 3 points while its English result fell 4. SchoolDigger places Junior/Senior High at the 23rd percentile in 2025–2026, down 15 percentile points from 2023–2024. Attendance is a concern at Abel: chronic absenteeism was 64%, versus 18% statewide. As context, five schools reported a free/reduced lunch eligible measure for 2024–2025, ranging from 81% at Abel to 92% at Junior/Senior High and Upper Elementary; Coastal Buttes instead reported 25% directly certified for free meals that year, a different measure.
