Summary:
ZIP code 97017 is home to a single high school, Colton High School, which serves grades 9–12 with 161 students as part of Colton School District 53.
Colton High's strongest result is its 92.5% graduation rate for 2024–2025, well above the district's 51.6% and the state's 83.0%. Its state ranking also improved sharply, from 246th of 270 (9th percentile, 0 stars) in 2024–2025 to 124th of 271 (54th percentile, 3 stars) in 2025–2026 — a gain of 122 places and 45 percentile points in one year. English Language Arts proficiency is solid at 46.3%, above the district's 37.7% and the state's 43.8%. Eleventh-grade mathematics, at 25.6%, matches the district and beats the state's 22.9%. The district itself ranks 98th of 141 statewide, in the 30th percentile with 2 stars, so the school's most recent standing is stronger than the district's overall percentile suggests.
The main concern is attendance: 49.1% of students were chronically absent in 2024–2025, far above the district's 30.9% and the state's 33.5%. Math and science remain below state levels in the all-grade figures — mathematics at 25.6% versus 32.9% statewide, and science at 28.9% versus 30.6%. Eleventh-grade science, 28.9%, also trails the state's 33.8% while edging the district's 28.2%. Because high school testing is concentrated in grade 11, the all-grade and 11th-grade results are identical. The school serves a majority economically disadvantaged population, with 64.6% receiving free or reduced-price lunch; per-student spending is $20,396 and the student-teacher ratio is 20.1, figures best read as descriptive, since no district or state comparison was provided.
