Summary

Thunder Basin High School serves 1,206 students in grades 9–12 in Gillette, as part of Campbell County School District #1. Its latest WY-TOPP results show a clear strength in mathematics, with proficiency above both state and district levels in 9th and 10th grade. Most importantly, Thunder Basin leads nearby schools in every reported 10th-grade subject and in the available 9th-grade comparisons.

Mathematics is the school’s strongest subject against benchmarks: 10th-grade proficiency is 53%, 8 points above the state and 4 points above the district; 9th-grade proficiency is 59%, 13 points above the state and 8 above the district. In 10th-grade science, 60% proficiency is 6 points above both the state and district. ELA is a relative weakness against the state: results are 50% in 10th grade and 48% in 9th, respectively 5 and 7 points below the state, though slightly above the district in both grades. In the nearby-school comparison, Thunder Basin also leads Campbell County High School and Westwood High School in all three 10th-grade subjects. Westwood’s 9th-grade results were not available, so those comparisons are with Campbell County alone.

Results over time are mixed: from 2022–23 to 2025–26, 10th-grade science rose 18 points and 9th-grade math rose 6, while 9th-grade ELA fell 1 point and remains below the state. SchoolDigger ranks Thunder Basin 34th of 81 statewide, at the 58th percentile with 3 stars, ahead of Campbell County (42nd percentile, 2 stars) and Westwood (7th percentile, 0 stars). Its student-teacher ratio is 16.1 in 2024–25, the highest among the three; 28% of students were free/reduced lunch eligible that year, the lowest reported share among them. A notable subgroup result is SchoolDigger’s 17th-percentile statewide ranking for how well the school serves Special Education Students in 2025–26, compared with 58th overall and down from the subgroup’s 40th percentile the prior year. Graduation was 84% in 2024–25, above the state’s 83%, but down 7 points from the school’s 91% rate in 2020–21.
