Summary:
ZIP code 95237 has one listed school, Lockeford Elementary, serving kindergarten through eighth grade, with 541 students. In 2025–2026, 23% of students were proficient in English language arts (ELA), 19% in math, and 14% in science; Lodi Unified results were 40%, 30%, and 26%, respectively. State results were 49% in ELA, 38% in math, and 36% in science. The most important finding is that Lockeford scored below the state in all three subjects, with its widest state gap in ELA: 26 percentage points.
Because Lockeford is the only school in the ZIP-code list, it is both the highest- and lowest-scoring school locally; there is no second school for a direct comparison. Within Lockeford, results vary by grade: third-grade math was its strongest result at 26%, while sixth-grade math was lowest at 11%. Sixth-grade ELA is a particular concern: 13% of students were proficient, compared with 48% statewide, a 35-point gap. Eighth-grade math was the closest grade-level result to the state, at 19% versus 36%, a 17-point gap.
Year-over-year results were mixed: Lockeford’s ELA proficiency fell by 2 percentage points and math by 1 point, while science improved by 5 points. The state gap widened by 2 points in both ELA and math but narrowed by 1 point in science; averaged across the three subjects, the gap widened by 1 point. SchoolDigger’s rating fell from two stars in 2023–2024 to one star in the next two years, and its percentile ranking dropped from the 40th to the 11th. As context, the student-teacher ratio was 24.2 in 2024–2025, and 73% of students were free/reduced lunch eligible that year; these figures do not establish what explains the achievement results.
