Summary:
Zip code 95713 has one high school, Colfax High, serving grades 9–12 and enrolling 611 students, so families have no other local high school in this list to compare it with. Its strongest 2025–26 result was English language arts (ELA): 78% of students were proficient, compared with 49% statewide, a 28-point advantage. Science proficiency was 50%, 14 points above the state’s 36%. The most important finding is that ELA is a clear strength, while all-grades math was essentially at the state level: 38% at Colfax versus 38% statewide, about 1 point lower.
Colfax High is both the highest- and lowest-performing school in this list because it is the only school; there is no meaningful local school ranking. Within its results, ELA stands out and math is the relative weak spot. For 11th graders, however, Colfax was above state results in all three subjects: by 20 points in ELA, 6 in math and 12 in science. Beyond tests, the school’s 2025–26 graduation rate was 99%, compared with 88% statewide and 97% in the Placer Union High district. Dropout was 1% versus 8% statewide, and chronic absenteeism was 13% versus 18% statewide.
Recent test-score changes were mixed: from 2024–25 to 2025–26, Colfax ELA proficiency rose 16 points, while math fell 12 points and science fell 2 points. SchoolDigger’s statewide ranking also moved down, from 204th of 2,159 schools (91st percentile, 5 stars) in 2023–24 to 376th of 2,137 (82nd percentile, 4 stars) in 2025–26, despite the ELA improvement. In 2024–25, the school reported a 22:1 student–teacher ratio and 21% free/reduced lunch eligible; these are context measures, not explanations for results. With only one school listed, the data cannot show how results compare across local schools.
