Summary
Jackson Elementary serves 374 students in grades K–6 in Sanger, as part of the Sanger Unified area. Its 2025–26 proficiency was 43% in English language arts (ELA), 30% in math, and 17% in science. Science is the clearest concern: Jackson’s 17% was 19 points below both the state and nearby-school averages, and 23 points below the district.
ELA is Jackson’s strongest subject compared with the state, district, and nearby schools, though its results remain lower than all three: 43%, versus 49% statewide, 55% districtwide, and a 54% nearby-school average. Math is a larger shortfall: Jackson’s 30% was 8 points below the state, 13 below the district, and 17 below the nearby-school average; only one nearby school scored lower. Third grade is a bright spot, with 60% proficiency in both ELA and math. Later-grade math is weaker: results in grades 4–6 ranged from 21% to 24%, below state results in each grade.
Results have improved recently in ELA and math: since 2022–23, ELA rose 11 points to 43% and math rose 7 points to 30%, narrowing their gaps with the state. Science stayed at 17%, while the state improved, widening the gap. SchoolDigger’s overall ranking rose from the 24th percentile and 1 star in 2024–25 to the 42nd percentile and 2 stars in 2025–26; Jackson now ranks 3,381 of 5,804 California schools. Its 2024–25 student-teacher ratio was 22.5, near the middle of the nearby-school range, and 82% of students were free/reduced lunch eligible that year. Chronic absenteeism also improved, from 40% in 2021–22 to 19% in 2025–26, close to the state’s 18% but above the district’s 13%. One subgroup result merits attention: SchoolDigger’s measure of how well Jackson serves English Language Learner Students ranked at the 6th percentile in 2023–24, compared with the school’s overall 29th percentile that year; in 2021–22, the group ranked at the 65th percentile. The data provided do not include annual subgroup results between those years.
