Summary

Aileen Colburn Elementary is a K–6 school in Atwater, California, serving 371 students in the Atwater Elementary district. Its 2025–26 proficiency rates were 40% in English language arts (ELA), 30% in math and 17% in science, each below state and district results. The clearest concern is sixth grade: proficiency was 26% in ELA and 15% in math, 22 and 22 percentage points below state results, respectively.

Science is the school’s weakest subject in the local comparison: its 17% proficiency was below the nearby-school average of 33%, and only Winfield Elementary had a lower result. Aileen ranked second-lowest among 11 nearby schools in math and fourth-lowest in ELA; its results were 30% in math and 40% in ELA, compared with nearby averages of 39% and 45%. There are brighter grade-level results: fourth-grade ELA was 51%, the highest among nearby schools reporting that grade and 5 points above the state. But fourth-grade math was 31%, below both district and state results, so the stronger showing is concentrated in one subject.

Results have moved unevenly: from 2022–23 to 2025–26, ELA rose 3 percentage points and math rose 2, while science fell 1; all three subjects declined in the latest year. SchoolDigger rated Aileen at the 38th percentile with 2 stars in 2025–26, the third-lowest standing among the 11 schools, down 7 percentile points from the prior year. In 2024–25, 92% of students were free/reduced lunch eligible, and the student-teacher ratio was 21.8:1, the lowest among nearby schools in its district. SchoolDigger’s statewide ranking for English Language Learner Students was comparatively higher—57th percentile in 2023–24 versus 39th overall—but had fallen from the 84th percentile in 2021–22. Nearby schools have different grade spans, and results at this enrollment can shift with relatively small changes in student counts.

I use to go to this school when i was young, and the atmosphere and teachers were great. if i could do it again, there wouldn't be any other school i would have gone to. Most memorable teacher was my third grade teacher who was great. She really cared about her students and i remember trying really hard to beat her 1 minute math quizzes, which i did and got to go to frosty freezes to get a banana split. Close Quote
