Summary
San Mateo Park Elementary is a K–5 school in San Mateo, serving 340 students in the San Mateo-Foster City district. The most important finding is that its 2025–26 proficiency results were far below district and state results and below every nearby K–5 school in English language arts (ELA), math, and science.
There is no tested subject in which the school stands out positively against nearby schools. Proficiency was 4% in ELA, 6% in math, and 0% in science, compared with district results of 53%, 50%, and 45%, and state results of 49%, 38%, and 36%, respectively. Nearby K–5 averages were 69% in ELA, 71% in math, and 62% in science; San Mateo Park’s result was below even the lowest nearby result in each subject. ELA is the weakest relative to both district and state, with gaps of 49 and 46 percentage points. Science is the least far behind the nearby average, but its 62-point gap is still substantial.
Results have declined across the four test years: from 2022–23 to 2025–26, proficiency fell 14 points in ELA, 17 in math, and 21 in science, while the gaps to the state widened by 17, 21, and 27 points. Chronic absenteeism has improved by 10 points since 2021–22, but at 27% in 2025–26 it remained higher than the district’s 15%, the state’s 18%, and every nearby school. SchoolDigger placed the school at the 0th percentile, with 0 stars, in 2025–26; its rank was 5,799 of 5,804. Its student-teacher ratio was 24.2 in 2024–25, the third-highest among the comparison schools, and 64% of students were free/reduced lunch eligible that year, the second-highest nearby rate. A notable SchoolDigger subgroup result is that its statewide measure of how well the school serves special education students fell from the 74th percentile in 2022–23 to the 4th percentile in 2025–26.
