Dietrich School

Dietrich School is a small alternative PK-12 school in Dietrich, Idaho, serving 173 students in the Dietrich District. With a low student-teacher ratio of 10.3 to 1, students are likely to receive plenty of individual attention. About half of the student body (50.3%) qualifies for free or reduced-price lunch, indicating a moderate level of economic need. Its nearest comparable school is Richfield School, located about 11 miles away, which serves 208 students and has a higher poverty rate of 73.1%.

Academically, Dietrich School excels in core subjects. On the 2025–2026 ISAT assessments, Dietrich School posted math proficiency of 50.6% and English language arts proficiency of 61.3% — both above the Idaho state averages of 43.1% and 54.0%, and well ahead of the 32.7% and 34.5% posted by Richfield School. This strength has been consistent for three consecutive years. Science, however, is a clear exception: only 30.6% of Dietrich School students scored proficient, below both Richfield School (38.0%) and the state (42.7%). Attendance is a major plus, with a chronic absenteeism rate of just 10.4%, compared to 13.8% statewide and 18.4% at Richfield School. Dietrich School's graduation rate of 82.5% matches the state average, though it has swung between 80% and 100% in recent years — not unusual for a school with very small graduating classes.

Dietrich School achieves these strong results while spending less per student than its neighbor — about $10,869 versus $12,525 at Richfield School — and has maintained academic momentum even as economic need has risen. Performance does vary by grade level: middle school math is a particular standout, while 4th-grade math and high school end-of-course English language arts trail state averages slightly. For parents, Dietrich School offers a well-attended, supportive environment with solid math and reading instruction; science is the clearest area where improvement is needed.
