Summary:
Zip code 92014 has two K–6 elementary schools in the Del Mar Union Elementary district: Del Mar Heights Elementary and Del Mar Hills Elementary. Both schools’ 2025–2026 results are well above California’s in English language arts (ELA), math, and science. The area’s clearest comparative strength is math: the schools’ average is 85% proficient, 47 percentage points above the state result.
Del Mar Hills leads in all-grade ELA and math, while Del Mar Heights leads in science. Hills has 86% proficiency in ELA versus Heights’ 85%, and 89% in math versus 82%—a 1-point ELA lead and a 7-point math lead. Heights’ fifth-grade science result is 68%, compared with Hills’ 66%; both are above the state’s 35% but below the district’s 71%. Grade-level results add nuance: Hills leads in fifth-grade math, 83% to Heights’ 70%, while Heights leads in fourth-grade math. So the all-grade averages do not mean either school leads at every grade or in every subject.
Across the two years reported, the schools’ average ELA and math results rose by about 2 percentage points, while science fell by 10 points. The school-state gap widened in ELA, from 34 to 36 points, and math, from 46 to 47; in science it narrowed from 44 to 31 points. The individual trends differed: Hills improved by 8 points in ELA and 7 in math, while Heights’ results fell by 4 and 2 points, respectively. SchoolDigger gives Hills a five-star rating and ranks it 72nd of 5,804 statewide; Heights also has five stars and ranks 119th. Hills has a lower student-teacher ratio (16.4 versus 18.3). Both report free/reduced lunch eligible for 2024–2025, at 9% for Hills and 10% for Heights—similar figures that provide context, not an explanation for results. The comparisons cover only two years, so they show recent changes rather than a long-term trend.
