Summary
Walter F. Dexter Middle serves 610 students in grades 6–8 in Whittier, in the Whittier City School District. The clearest concern is mathematics, especially in seventh grade: just 17% of Dexter seventh-graders were proficient in 2025–26, compared with 38% statewide and 33% in the district. That result was the lowest seventh-grade math score among the nearby schools.
Science is Dexter’s strongest subject relative to nearby schools, while math is its largest weakness. Dexter ranked fourth of 11 nearby middle schools in science and was above their average: 32% proficient, compared with 29%. It ranked seventh in ELA and sixth in math, scoring 42% and 26%, respectively, below nearby averages of 46% and 31%. Dexter remained below the state and district in all three subjects: the gaps were 7 points in ELA, 12 in math, and 4 in science versus the state; versus the district, they were 9, 14, and 1 point. Even in science, its closest comparison, Dexter has not yet reached state or district results.
Scores have improved since 2022–23: ELA rose 10 points, math 8, and science 12, though the current ELA and math gaps remain. Attendance is another concern: chronic absenteeism was 26% in 2025–26, the highest among nearby schools, and 8 points above both the state and district rates; it has fallen 6 points since 2021–22. SchoolDigger places Dexter at the 44th percentile with 2 stars, up from the 31st percentile the year before. Its student-teacher ratio was 21.3 in 2024–25, close to the nearby average of 21.5. In 2024–25, 87% of students were free/reduced lunch eligible, 3 points above the nearby average. SchoolDigger’s statewide measure suggests the school serves Hispanic students comparatively well, at the 59th percentile in 2025–26 versus 44th overall; its measure for homeless students rose sharply, from the 31st percentile in 2024–25 to the 70th in 2025–26.
