Summary:
Lemoore Union High includes two schools serving grades 9–12: Lemoore High and Jamison (Donald C.) High (Continuation). In 2025–2026, their equal-weight average proficiency was 44% in English language arts (ELA), 12% in math and 23% in science, compared with state results of 49%, 38% and 36%. Math was the area’s clearest shared weakness relative to the state, with the average 27 percentage points lower. Most importantly, results differ sharply by school: Lemoore led Jamison in every subject, while Jamison fell below the state in all three.
Lemoore High stands out at the top: its 2025–2026 proficiency was 64% in ELA, 24% in math and 34% in science, compared with 25%, 0% and 13% at Jamison. Those differences are 39 percentage points in ELA, 24 in math and 22 in science. Lemoore was 15 points above the state in ELA, but 15 below in math and 2 below in science; Jamison was 24, 38 and 23 points below the state, respectively. SchoolDigger ranked Lemoore 847th of 2,137 schools (60th percentile, 3 stars) and Jamison 1,721st (19th percentile, 1 star). Other measures tell a more mixed story: graduation rates were 97% at Lemoore and 98% at Jamison, while chronic absenteeism was 15% and 56%, respectively.
Recent score trends do not point to one shared direction. From 2024–2025 to 2025–2026, Lemoore’s ELA proficiency fell 2 percentage points, math rose 1 point and science was nearly unchanged. Jamison’s ELA fell 10 points, math remained at 0%, and science rose 8 points; state results increased in all three subjects. Enrollment and school context also differ: Lemoore had 1,798 students and a 20.3 student-teacher ratio, compared with Jamison’s 90 students and 12.2 ratio. Both reported free/reduced lunch eligible for 2024–2025: 59% at Lemoore and 79% at Jamison. These are context measures, not explanations for school outcomes.
