Summary:
Zip code 90034 has eight schools serving elementary, middle, and high school grades: five elementary schools, one middle school, and two high schools. In 2025–26, the schools’ average proficiency was about 54% in ELA, 48% in math, and 45% in science, compared with state rates of 49%, 38%, and 36%. Those averages are above state rates, but they conceal a pronounced divide: some schools score far above the state while others are well below it.
Clover Avenue Elementary leads in math at 85% and science at 74%, while Castle Heights Elementary leads in ELA at 85%; their ELA results are especially close, at 84.7% and 84.8%, respectively. SchoolDigger ranks Clover Avenue at the 98th statewide percentile and Castle Heights at the 97th. Charnock Road Elementary is another strong performer, particularly in math. At the other end, Cheviot Hills Continuation has the lowest reported ELA and math results—6% and 0%—and its science result is suppressed. Palms Elementary is lowest among the elementary schools in all three subjects, with 36% in ELA, 32% in math, and 13% in science.
Results generally improved from 2024–25 to 2025–26, but not at every school. Charnock Road gained 8 points in ELA, 21 in math, and 21 in science; by contrast, Clover Avenue declined by 1, 2, and 4 points in those subjects while remaining a leader. SchoolDigger’s percentile ranking rose from 59th to 83rd at Charnock Road and from 40th to 49th at Shenandoah Street Elementary. School size and student-teacher ratios alone do not explain the differences: Castle Heights and Clover Avenue have ratios of 22.7:1 and 22.2:1, while Palms Elementary’s is 16.3:1. The reported free/reduced lunch eligible figures for 2024–25 range from 33% at Castle Heights to 93% at Shenandoah Street. Cheviot Hills reports 56% directly certified for free meals in 2024–25, a different measure.
