Schools in Firth, ID

Firth, Idaho, is served by three public schools within the Firth District: Firth High School (grades 9–12, 305 students), A W Johnson Elementary School (grades PK–4, 256 students), and Firth Middle School (grades 5–8, 247 students), for a total of 808 students across this small rural community. The district ranks 23rd out of 101 Idaho districts — the 77th percentile — with a 4-star rating, and every school in the district earned a 3-star rating in 2025–2026.

Firth High School stands out for its strong English language arts and math scores, with 69.9% ELA proficiency and 45.2% math proficiency on end-of-course exams — both well above state averages — along with an exceptionally low 3.3% chronic absenteeism rate. A W Johnson Elementary School combines the district's highest poverty rate (49.2% free/reduced lunch) with the district's highest math proficiency (52.6%) and above-average ELA scores (60.8%), while spending the least per student at $5,642. Firth Middle School posts strong ELA proficiency (59.3% vs. 54.0% statewide) and excellent 8th-grade science results (50.8% vs. 42.9% statewide). However, high school science proficiency trails the state average, and the middle school's 5th-grade science scores lag significantly.

The most striking trend is district-wide improvement: every Firth school jumped substantially in state percentile rank from 2024–2025 to 2025–2026 (high school 39th to 64th, elementary 33rd to 69th, middle school 35th to 59th), reflecting a genuine turnaround over the past several years. Chronic absenteeism is remarkably low across all three schools, ranging from 3.3% to 7.1%, far below the 13.8% state average. Spending does not clearly predict outcomes — the high school spends the most per student ($8,587) but does not outperform the lower-spending elementary school. The high school's graduation rate of 82.5% matches the state average exactly, which is worth monitoring. For parents, the main watch items are science proficiency in high school and early middle grades, along with continued attendance efforts at the middle school.
