What the NCES Data Says About Idaho Schools

Idaho operates 778 public K-12 schools organised into 183 independent school districts serving 315,098 students, per the National Center for Education Statistics Common Core of Data 2024-25. The largest district, Joint School District No. 2, enrolls 39,496 pupils across 61 schools at $8,438 per student, while smaller rural districts can run fewer than a dozen campuses. This fragmentation — inherited from century-old township governance patterns in many states — is why per-pupil spending, class sizes, and programme availability vary dramatically inside a single state boundary.

Statewide, the average student-teacher ratio is 17.3:1, a useful benchmark for comparing any individual district or school on PlainSchools. Free-lunch eligibility averages 29.3% across Idaho public schools, a federal indicator of economic need that drives Title I funding allocations. The district table below is sortable by enrollment, school count, and per-pupil expenditure — the three fields that best predict a district's financial and demographic profile. For schools specifically, use the rankings links above to view per-category leaderboards covering spending, class size, best schools by composite quality score, chronic absenteeism, and funding-equity distribution within the state.

Every district figure here pulls from two distinct federal surveys: enrollment and demographic data come from the NCES Common Core of Data 2024-25 (school membership and directory), while per-pupil spending, teacher salaries, and federal/state/local revenue shares originate in the NCES F-33 School District Finance Survey (typically FY 2021-22). Civil-rights indicators — gifted enrollment, AP course counts, counselor staffing, chronic absenteeism, in- and out-of-school suspensions — come from the 2021-22 Civil Rights Data Collection. Cross-referencing these three sources is what lets PlainSchools produce composite scores and equity rankings that single-source tools cannot.

Idaho per-pupil spending varies 16.1× across districts

Per-pupil spending in Idaho ranges from $5,040 (lowest district) to $81,000 (highest), a spread of $75,960. That ratio is among the widest in the country and predicts large gaps in class size, programme availability, and counselor:student ratios that compound across a 12-year K-12 career. High-spending districts typically draw on higher property tax bases, a structural feature of state education finance under the federal Title I framework that sets the floor but not the ceiling.

Average Idaho student-teacher ratio is 17.3:1 — near the U.S. average of approximately 16:1

Student-teacher ratio is the simplest staffing metric reported on NCES Common Core of Data, but it does not capture push-in specialists, intervention staff, English Language Learner aides, special education co-teachers, or counseling and support staff. Variation between districts within the state is wider than the state-average figure suggests — large urban districts may run 20:1 while small rural districts run 10:1, both inside the same average. Class-load comparisons are most meaningful at the district or school level, not the state aggregate.

Using the Idaho data

Idaho's 778 schools sit inside 183 districts — compare at the district level first.

  • District boundaries decide enrollment: shortlist 2-3 districts on spending, ratio, and size before comparing individual schools. Compare districts
  • Check how Idaho distributes money across its districts — funding equity varies more within states than between them. Funding equity
  • Verify any school's federal record (enrollment, staffing, CRDC flags) before a visit or enrollment decision. Look up a school

What is the largest school district in Idaho?

Why does per-pupil spending vary so much across Idaho districts?

Idaho districts spend between $5,040 and $81,000 per pupil — a 16.1× range. Most U.S. states fund schools through a mix of state aid (typically 40-60%), local property tax (30-50%), and federal Title I (5-15%). Districts in higher property-value areas raise more per pupil from local taxes, while state aid is intended to partially equalise but rarely closes the full gap. The federal F-33 finance survey reports actual current expenditures including instructional and support services.
