Summary

Thunder Ridge High School is a large comprehensive public high school in Idaho Falls, ID, serving 1,693 students in grades 9–12 as part of the Bonneville Joint District. It is the largest high school in the area, well above Bonneville High School (1,176) and Hillcrest High School (1,230). Roughly 27% of students qualify for free or reduced-price lunch, reflecting a moderately lower-income population compared to some nearby schools.

Strong attendance and historically high graduation rates are notable strengths. Chronic absenteeism runs well below district and state averages (11.2% vs. 13.4% district and 13.8% state in 2025-26), and graduation rates were consistently above 90% in recent years. English language arts proficiency is another bright spot — the school beat its district average in 2025-26 (54.2% vs. 51.1%), though it trails the state (61.3%). Compared with nearby schools, Thunder Ridge outperforms Bonneville High School in ELA and science, but trails Hillcrest High School, which is just 2.8 miles away with a similar income profile yet posts far higher math (32.2% vs. 17.1%), science (44.7% vs. 25.3%), and ELA (69.8% vs. 54.2%) scores.

The biggest academic concerns are math and science proficiency. In 2025-26, only 17.1% of Thunder Ridge students were proficient in math and 25.3% in science — both below district and state averages. State ranking has declined from 65th (3 stars) in 2023-24 to 98th (1 star) in 2025-26, driven more by test scores than attendance or graduation. Achievement gaps for Hispanic and low-income students are also a significant concern, with subgroup rankings far below the school's overall averages. Parents considering Thunder Ridge should weigh its excellent attendance, solid literacy outcomes, and strong graduation history against the math/science challenges and the notable gap compared to nearby Hillcrest High School.
