Summary

Guin Foss Elementary is a K–5 school serving 395 students in Santa Ana, California, within Tustin Unified. Its results show a clear subject split: math is a relative strength, while science is the main academic concern because it trails most nearby schools.

In 2025–2026, math proficiency was 60%—22 percentage points above the state, 4 above the district, and 2 above the average for the 10 nearby schools; Guin ranked fifth among those schools. ELA was 58%, 9 points above the state but 6 below the district and roughly level with nearby schools, also placing fifth. Science was 32%, 4 points below the state, 18 below the district, and 16 below the nearby-school average. Only three of the 10 nearby schools had lower science results, making this the clearest area to ask about.

ELA and math have improved over four test years: ELA rose 7 percentage points and math 11, while science increased only 3 points overall and has fluctuated; its state gap widened to 4 points below in 2025–2026. SchoolDigger ranks Guin 1,483rd of 5,804 schools, at the 74th percentile with 4 stars. That is up from the 67th percentile in 2022–2023, but below its 86th-percentile standing in 2015–2016. The student-teacher ratio was 25.4 in 2024–2025, close to the nearby average of 25.7; free/reduced lunch eligible students made up 62% in 2024–2025. Chronic absenteeism also fell from 27% in 2021–2022 to 10% in 2025–2026. One subgroup result stands out: SchoolDigger’s measure of how well the school serves White students moved from the 88th percentile in 2023–2024 to the 62nd in 2024–2025, then back to the 80th in 2025–2026—a notable fluctuation rather than a sustained decline.
