Skyline Senior High School

Skyline Senior High School is a large public high school in Idaho Falls, ID, serving about 1,336 students in grades 9–12 as part of the Idaho Falls District. The school recently earned a 4-star rating and ranked 38th out of 122 Idaho high schools, placing it in the 69th percentile—a dramatic jump from the previous year's 2-star rating. Among the large traditional public high schools in the area, Skyline now ranks the highest, surpassing both Idaho Falls Senior High School and Hillcrest High School, as well as Bonneville High School farther out. Only the much smaller Compass Academy and Alturas Preparatory Academy charter schools rank higher.

The clearest academic strength at Skyline Senior High School is English Language Arts, with proficiency rates that have exceeded both district and state averages in every recent reporting year. On the most recent End-of-Course tests, Skyline also topped state averages in math (41.9% proficient vs. 33.1% statewide) and science (46.8% vs. 41.2% statewide)—a sharp reversal after several years of lagging behind in those subjects. The graduation rate (76.1%) remains above the district average but trails the state average by roughly six points. Chronic absenteeism sits at 17.3%, better than the district but above the state's 13.8% figure.

Skyline serves a student body with significant economic need—41.1% of students qualified for free or reduced lunch in 2024-2025, the highest among large nearby comprehensive high schools—yet it still produces competitive results while spending less per student (~$7,846) and maintaining larger class sizes than smaller local schools. The main concern is subgroup performance: female, male, Hispanic, and low-income students have all scored near or below the 21st percentile in recent statewide subgroup rankings, suggesting the school's overall rating masks gaps in serving specific populations. Whether Skyline can sustain its recent gains and close those subgroup gaps will be the key measure of success in the years ahead.
