Summary:
The six high schools listed for Hanford Joint Union High serve grades 9–12, from large traditional campuses to online, continuation, and community-day settings. Results vary sharply by school: among reported 2025–2026 scores, proficiency ranges from 14% to 67% in ELA and from 3% to 39% in math. The most important finding is that Sierra Pacific High is the only school above the state in all three reported subjects.
Sierra Pacific High leads in ELA (67%), math (39%), and science (38%), topping state results by 17, 1, and 2 percentage points, respectively. Hanford West High is next strongest overall: its 56% ELA result is 6 points above the state, and its results exceed Hanford High in all three subjects. At the lower end, Earl F. Johnson High (Continuation) has the lowest reported ELA and math results, at 14% and 3%; Hanford Online Charter has the lowest reported science result, at 10%. Hanford Community Day has suppressed test results, so it cannot be ranked in those subjects. SchoolDigger’s separate rankings also place Sierra Pacific highest (74th percentile, 4 stars) and Johnson lowest (10th percentile, 0 stars).
Results have improved in math and science on average, though not at every school: the tested-school averages rose by 7 percentage points in math and 6 in science from 2024–2025 to 2025–2026, while ELA increased by 1 point. Hanford West had particularly large gains—18 points in math and 11 in science—while Hanford High’s ELA fell 10 points. Graduation rates are strong at several schools: Hanford West and Sierra Pacific each report 100%, while Johnson reports 77%; attendance is a concern at Johnson (46% chronic absenteeism) and Community Day (79%), compared with 20% districtwide. In 2024–2025, the free/reduced lunch eligible measure ranged from 59% at Sierra Pacific to 96% at Johnson; student-teacher ratios also varied, from 10.4 at Johnson to 26.1 at Sierra Pacific. These are differences among school settings, not explanations for results.
