High Schools in Twin Falls District

The Twin Falls District in Idaho includes three high schools serving grades 9–12: Canyon Ridge High School, Twin Falls High School, and Magic Valley High School. Combined, they enroll about 2,987 students, but the schools are very different in size, academic performance, and student needs.

Twin Falls High School is the clear academic standout. It ranks 16th out of 122 Idaho high schools (87th percentile, 4 stars) for 2025–26, and it outperforms the district and state in every subject with available data. It also has the lowest chronic absenteeism (14.7%) and the lowest poverty rate (29.76% free/reduced lunch) among the three schools. Interestingly, it does this with the highest student-teacher ratio (21.4). Canyon Ridge High School is the largest school but sits in the middle: it ranks 48th (61st percentile, 3 stars), with strong English scores but math and science proficiency below state averages. Magic Valley High School is a much smaller, high-need alternative school with 161 students, a 55.7% chronic absenteeism rate, the highest poverty rate (45.96%), and no recent test-score data, making its academic standing hard to compare directly.

Key takeaways for parents: attendance and poverty align closely with achievement, as Twin Falls High leads the district in every category while Canyon Ridge trails in math and science. Chronic absenteeism is a district-wide concern, especially at Magic Valley, where more than half of students miss school chronically. Higher spending per student does not guarantee better outcomes—Magic Valley spends $12,323 per student versus about $8,200–$8,400 at the other schools, yet shows no measurable academic advantage. Also, the graduation rate is reported at exactly 82.5% for all schools, the district, and the state, which is likely a data artifact rather than a true comparison. Overall, parents looking at this district should note that Twin Falls High School offers the strongest academic profile, while the other two schools serve larger or higher-need populations with more variability.
