Alturas International Academy Inc.

Alturas International Academy Inc. is a single-school district in Idaho Falls, ID, serving grades K through 5 at Alturas International Academy, which enrolls 572 students and currently ranks 94th out of 346 Idaho elementary schools — placing it in the 73rd percentile with a 4-star rating. The school outperforms the state in every reported subject area, with particularly strong results in English Language Arts and Science. All-grades ELA proficiency is 67.6% versus the state’s 54.0%, and 5th-grade science proficiency is 58.0% compared to the state’s 44.0%. The largest academic advantages come in upper-elementary ELA: 3rd graders score 69.9% proficient (+21.4 points over the state) and 5th graders score 78.4% proficient (+23.2 points over the state), showing that literacy development is a clear strength as students advance.

Math proficiency follows a different pattern. While the school still beats state averages, math scores decline from 57.0% in 3rd grade to 48.5% in 4th grade and 45.5% in 5th grade. This downward trend suggests an opportunity to strengthen math instruction in the upper elementary grades, even though the school’s overall math score of 50.4% remains above the state’s 43.1%. Science is another standout area, with 5th graders exceeding the state by 14 percentage points. The school’s district rank is also excellent — 15th out of 101 Idaho districts (85th percentile) — and since this is a single-school district, that ranking directly reflects Alturas International Academy’s performance. After dipping to the 59th percentile in 2024–2025, the school jumped to the 73rd percentile in 2025–2026, gaining a star and improving by 45 ranking spots.

Attendance and resources are worth noting. The chronic absenteeism rate is 15.8%, two points above the state average, which is a concern even though academic results remain strong. About one-third of students (33.57%) qualify for free/reduced lunch, indicating moderate economic diversity. The student-teacher ratio is 22.4 to 1, which is relatively high for an elementary school, and per-student spending data from 2018–2019 shows $6,935 — a figure that may not reflect current funding levels. Overall, Alturas International Academy is a high-performing school with impressive literacy and science outcomes, a strong upward trajectory, and manageable areas for improvement in math progression and attendance.
