Glenns Ferry High School

Glenns Ferry High School is a small public high school in Glenns Ferry, Idaho, serving 128 students in grades 9 through 12 as part of the Glenns Ferry Joint District, with no other schools located within 20 miles of the campus.

Academically, the school shows a mixed picture. Math proficiency was 23.7% in 2024–2025, well below the state average of 43.1%, and science proficiency was 32.4% compared with 42.6% statewide. English Language Arts is a relative bright spot: the school's all-grades ELA proficiency of 52.6% nearly matched the state average of 53.9% and significantly outperformed the district's 40.2%. The school benefits from a low student-to-teacher ratio of about 13 to 1, meaning students likely receive more individualized attention. Chronic absenteeism is also a positive differentiator, with the school consistently beating both district and state averages — just 11.0% in 2025–2026 compared with 13.8% statewide.

Graduation rates have been volatile, ranging from 85.7% in 2020–2021 to a concerning 66.7% in 2023–2024 before recovering to 82.5% in 2024–2025, which exactly matched the state average. The percentage of students eligible for free or reduced-price lunch has climbed sharply from about 33% in 2022–2023 to over 51% in 2024–2025, reflecting a growing share of economically disadvantaged families. While the school has posted some encouraging statistics — especially attendance and ELA — its overall ranking remains in the lower percentile of Idaho high schools, indicating that math and science proficiency and graduation stability are key areas needing continued attention.
