Firth District is home to a single middle school, Firth Middle School, which serves grades 5 through 8 with an enrollment of 247 students. The Firth District is ranked 23rd out of 101 Idaho districts, placing it in the 77th percentile with a 4-star rating. Firth Middle School itself has shown a remarkable upward trajectory, climbing from the 4th percentile statewide in 2017-2018 to the 59th percentile in 2025-2026. Over the most recent year, the school jumped from 108th to 71st place in the state rankings.

Academically, English Language Arts is a clear strength. Firth Middle School's ELA proficiency rate of 59.3% exceeds the state average of 54.0%, and it outperforms the state at every grade level from 5th through 8th grade. In 8th grade ELA, the school posts 65.6% proficiency versus 54.5% statewide. Math is an area for improvement, with an overall proficiency rate of 41.8% that trails both the district (44.9%) and state (43.1%). This is driven largely by 7th grade math, where only 36.5% of students are proficient compared to 43.6% statewide, while 6th grade math is a bright spot at 50.9%. Science results are mixed: 5th grade science lags at 33.3% versus 44.0% statewide, while 8th grade science shines at 50.8% versus 42.9%.

Firth Middle School also stands out for its attendance and context. The chronic absenteeism rate is 7.1%, well below the state rate of 13.8%, though higher than the district's 4.8%. With 39.27% of students eligible for free or reduced-price lunch, the school serves a moderate-poverty population yet achieves solid results, particularly in reading and writing. The student-teacher ratio is 15.1, and per-student spending was $6,437 in the 2018-2019 school year. While math and 5th-grade science are areas to watch, Firth Middle School is clearly on an upward path and well-positioned to continue improving its already strong standing within Idaho.
