Summary:
ZIP code 92007 has two elementary schools: Ada W. Harris Elementary, serving grades 3–6, and Cardiff Elementary, serving kindergarten–grade 2. The clearest finding for the area is that Ada’s 2025–26 results were above California’s in all three reported subjects.
In the available state comparison, Ada stands out: its results were 73% in ELA, 66% in math, and 60% in science, compared with 49%, 38%, and 36% statewide. Ada’s advantages were 24 points in ELA, 28 in math, and 24 in science, making math its strongest state-relative result even though its ELA score was highest. Because Cardiff serves K–2 and has no test results supplied, no school-to-school academic winner or lower-scoring school can be identified.
Ada’s scores moved in different directions from 2024–25 to 2025–26: ELA fell 4 points and math fell 2, while science rose 5; its lead over the state narrowed by 5 points in ELA and 4 in math, but widened by 2 in science. SchoolDigger gives Ada four stars and ranks it 610 of 5,804 schools, at the 89th percentile; its percentile has stayed close to that level over the past three years. Other comparisons offer context, not explanations for academic results: in 2024–25, student-teacher ratios were 22.4 at Ada and 21.5 at Cardiff, while per-student spending was $25,962 and $35,071, respectively. Their 2024–25 free/reduced lunch eligible figures were similar—11.0% at Ada and 11.2% at Cardiff. In 2025–26, chronic absenteeism was 5% at Ada and 6% at Cardiff, both well below the state’s 18%.
