Summary

Ada W. Harris Elementary serves 382 students in grades 3–6 in coastal Cardiff by the Sea. In 2025–2026, 73% of students were proficient in English language arts (ELA), 66% in math, and 60% in science. The most important takeaway is that Ada performed well above California’s results in all three subjects: its lead was 24 percentage points in ELA, 28 in math, and 24 in science.

Compared with nearby schools’ reported all-grades results, Ada was around the middle in ELA and math, ranking sixth of 10 schools in ELA and fifth of 10 in math; its scores were 73% and 66%, versus nearby averages of 70% and 65%. Science was a relative weakness locally: Ada’s 60% was below the nearby average of 62%, and it ranked fourth of nine. The supplied figures for Ada and the Cardiff Elementary district match exactly, showing no measured gap. One nearby school, Cardiff Elementary, serves K–2 and has no test scores supplied, and nearby all-grades results are not fully grade-matched to Ada.

Results have shifted over time: from 2022–2023 to 2025–2026, ELA rose by 4 points, while math fell by 3 points and science was nearly unchanged; math and science’s leads over the state narrowed. Chronic absenteeism improved from 16% in 2021–2022 to 5% in 2025–2026, compared with 18% statewide. Ada had an 89th-percentile rank and 4 stars from SchoolDigger in 2025–2026, close to its rank in recent years. Its student-teacher ratio was 22.4 in 2024–2025. The school reported 11% free/reduced lunch eligible that year, the second-lowest rate among the listed nearby schools. SchoolDigger’s measure of how well Ada serves students with low socioeconomic status rose to the 83rd percentile, from the 65th the prior year; its measure for multi-racial students was 66th percentile, 23 points below Ada’s overall percentile.
