Summary

Idaho Falls Senior High School is a large comprehensive public high school in Idaho Falls, ID, serving 1,298 students in grades 9–12 as part of the Idaho Falls District. English language arts is the school's clear academic strength, with 69.4% of students scoring proficient on the 2025–2026 End of Course ELA assessment — well above the district's 67.7% and the state's 61.3%. The school's graduation rate has consistently run 7–11 percentage points above the district average, reaching 84.9% in 2023–2024 and exceeding the state's 82.3% that same year.

Chronic absenteeism has improved dramatically, dropping from 20.0% in 2021–2022 to 14.0% in 2025–2026 — better than nearby Skyline Senior High School (17.3%) and far below the alternative schools Emerson High School (63.7%) and Lincoln High School (44.7%). However, math and science proficiency are notable weaknesses — only 28.7% of students were proficient in math and 33.6% in science for 2024–2025, both below state averages. Subgroup results are also uneven; Hispanic students ranked in the 35th percentile statewide in 2023–2024, and male and female students both fell near or below the state median that year.

Compared to nearby schools, Idaho Falls Senior High offers a different set of strengths than Skyline Senior High, located just 2.25 miles away. Skyline ranks higher statewide (38th vs. 53rd) with stronger math and science scores, but Idaho Falls Senior High edges out Skyline in ELA proficiency (69.4% vs. 68.3%), has lower chronic absenteeism, and serves a lower-poverty student population. The high-performing charters Compass Academy (ranked 8th in the state) and Alturas Preparatory Academy (31st) post higher test scores but struggle with attendance rates of 20.9% and 25.8% respectively. At about $7,967 per student, spending is moderate, and the school's strong literacy outcomes and graduation numbers suggest efficient use of funding. The free/reduced-price lunch rate rose from 22.7% to 30.8% in a single year — a trend worth monitoring — but the school's improving attendance and steady graduation rates make it a solid choice for families seeking a traditional, large high school experience.
