44 public K-12 schools in Idaho Falls from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
National city placement
According to NCES CCD 2024-25, Idaho Falls has more public-school enrollment than 93% of the 4,487 US cities in this directory. Idaho Falls is among the largest city school systems in this directory by enrollment, but its campuses are divided among 6 districts. That combination matters: citywide averages blend separate budgets, staffing policies, attendance boundaries, and program rules. For a family comparing schools here, the district column is as important as the city average; two nearby campuses may answer to different boards and draw on different F-33 funding pools.
29 of Idaho Falls's 44 listed schools use NCES's combined or “other” grade-level classification. Citywide averages therefore blend campuses serving unusually broad or nonstandard grade spans with conventional elementary, middle, and high schools. Grade configuration is a first-order comparison here, not a minor label.
The 74-point gap between Special Services Center and Alturas Preparatory Academy shows the range hidden by Idaho Falls's average Resource Investment Index. The city figure is useful for national placement, but families ultimately choose among campuses with different grade spans, enrollment, district affiliations, and reported support fields. Start with schools serving the relevant grade level, then compare the index components rather than assuming the city average describes any one classroom.
Idaho Falls school enrollment ranges from 9 students (lowest) to 1,693 students (highest), a spread of 1,684 students. That ratio is an extreme outlier spread — among the widest gaps observed anywhere in this dataset. Per-school staffing and program breadth can differ sharply at opposite ends of that enrollment range, so the city average should not be treated as a typical campus.

Each school district has independent budgeting, hiring, and service delivery authority. The fragmentation reflects historical patterns of inter-municipal boundary lines that pre-date modern city growth, students in different parts of the same city can attend different districts with different per-pupil spending, calendars, and graduation requirements. Per-region variation is largest in fragmented systems because each school district sets its own budget, contracts, and priorities without higher-level coordination above the regulatory floor.

student-teacher ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE classroom teachers against total enrollment, push-in specialists, English-language aides, special-education co-teachers, and counselors are not included in most reporting Higher values may reflect larger urban scale or recent resource constraints that have widened the gap.
Ranked by the Simpson student-body diversity index (0-100) from NCES race and ethnicity data, where higher means a more evenly mixed student body. It measures mix, not quality.
Special Services Center has the highest Resource Investment Index among the Idaho Falls schools in this federal-data comparison at 82/100. The index summarizes reported staffing, counseling, gifted-program, and attendance inputs; it is not an academic rating.
Idaho Falls has 44 public schools with a total enrollment of 21,448 students. 4 are charter schools. Average student-teacher ratio: 18.8:1.

Data from NCES Common Core of Data (CCD) 2024-25 and Civil Rights Data Collection (CRDC) 2021-22. The Resource Investment Index uses reported student-teacher ratio, counselor access, gifted programs, and attendance; it is not an academic rating. Cities must include at least five schools to be listed. This public-data comparison is for informational purposes: verify current enrollment, attendance boundaries, and programs with the school district before acting.
