Summary
Filer High School is a public high school in Filer, Idaho, serving roughly 500 students in grades 9–12 as part of the Filer District. In 2025–2026, the school ranked 41st out of 122 Idaho high schools, placing it in the 66th percentile with a 3-star rating — a solid result for the Magic Valley region. Only Twin Falls High School, ranked 16th, is clearly ahead locally, while Canyon Ridge High School, Hansen Junior/Senior High School, and Wendell High School all trail Filer in the state rankings.
Academically, Filer exceeds state averages on every core End of Course exam: 40.7% of students are proficient in math versus 33.1% statewide, 46.8% in science versus 41.2%, and 66.7% in English language arts versus 61.3%. What makes this more impressive is that the school achieves it while spending just $7,933 per student — well below most comparable schools, including Buhl High School at $10,439 and Twin Falls High School at $8,387. Class sizes are moderate at a 17.1-to-1 student-teacher ratio, offering more personal attention than the larger Twin Falls-area schools while still serving a mid-sized student body.
About 35% of Filer students qualify for free/reduced lunch, putting the school in the middle of the local pack economically, and the graduation rate has improved steadily to 82.5%, matching the state average. However, chronic absenteeism rose to 15.9% in 2025–2026 — above the state average of 13.8% — and the share of students facing economic need jumped significantly in a single year. Despite these challenges, Filer's test scores remain above state averages, a sign that the school has built academic resilience while supporting families under growing financial stress.
