Summary

Alturas Preparatory Academy is a public charter-style academy in Idaho Falls, ID, serving 463 students in grades 6 through 12 and operating as its own district, Alturas Preparatory Academy Inc. The school has climbed steadily in statewide rankings, moving from 62nd of 159 schools in 2023-24 to 31st of 122 in 2025-26 and earning a 4-star rating. Despite being a mid-size school, it competes academically with much larger neighbors like Hillcrest High School and Idaho Falls Senior High School.

Alturas stands out most in math and science. In 2025-26, 50.8% of students scored proficient in math and 58.5% in science, compared with 43.1% and 42.7% statewide. On end-of-course exams, the school led area high schools with 41.2% math proficiency and 63.6% in science, well ahead of Thunder Ridge High School (17.1% math, 25.3% science) and Bonneville High School (21.7% math, 24.3% science). ELA proficiency was competitive at 64.7%, just above the state's 61.3% and within a few points of the larger high schools.

The school's main challenges are attendance and equity. Chronic absenteeism runs at 25.8%, nearly double the state average of 13.8% and far higher than nearby schools like Hillcrest (9.1%) and Thunder Ridge (11.2%). The rate has improved steadily from 40% a few years ago, but it remains a concern. About 27% of students qualify for free or reduced-price lunch, and those students perform well below their peers, ranking in the bottom fifth statewide for their subgroup. Meanwhile, the school earned 4 stars for Hispanic student performance in subgroup rankings. Graduation rates sit at 82.5%, matching the state average. With a student-teacher ratio of 16.6 and clear academic momentum, Alturas has significant room to grow if it can improve attendance and close the achievement gap for low-income learners.
