High Schools in Firth District

Firth District in Idaho is served by a single high school, Firth High School, which enrolls approximately 305 students in grades 9 through 12. Because the district contains only one high school, district-level metrics mirror the school's performance in most reported categories. The school sits within a district that holds a 4-star rating and ranks 23rd out of 101 districts statewide, placing it in the 77th percentile of Idaho districts.

Firth High School stands out for its exceptionally low chronic absenteeism rate of just 3.3% for the 2025–2026 school year, compared to the state average of 13.8%. Students attend class at remarkably high rates, which likely supports academic achievement. On the 2025–2026 ISAT End-of-Course exams, Firth outperformed the state in math, with 45.2% of students proficient versus 33.1% statewide, and in English Language Arts, with 69.9% proficient versus 61.3% statewide. Science remains a relative weak spot, with 37.1% proficient compared to 41.2% across Idaho. The school's graduation rate stands at 82.5%, exactly matching the state average.

The school earned a 3-star rating for the 2025–2026 school year, ranking 44th out of 122 Idaho high schools, a solid improvement from the prior year's 68th-place finish out of 112 schools. About 27.5% of students qualify for free or reduced lunch, indicating a moderate level of economic diversity, and the student-teacher ratio is 18.5 to 1. Earlier ISAT results from 2024–2025, measured across all grades, showed the school below state averages in every subject, though those figures use a different metric than the recent End-of-Course results and should not be compared as a simple year-over-year trend. Overall, Firth High School offers strong attendance, competitive math and ELA scores, and a positive trajectory within a well-regarded district.
