Illinois Public School Types
NCES assigns one instructional type to each operating school; charter status is an overlapping classification.
| Classification | Schools | Share | Count rule | Period |
|---|---|---|---|---|
| All operating schools | 4,398 | 100.0% | Total | 2024–25 |
| Regular | 3,847 | 87.5% | School type | 2024–25 |
| Special education | 231 | 5.3% | School type | 2024–25 |
| Career and technical | 35 | 0.8% | School type | 2024–25 |
| Alternative education | 285 | 6.5% | School type | 2024–25 |
| Charter status | 131 | 3.0% | Overlapping status | 2024–25 |
Table analysis
- The four NCES school types add to 4,398 operating schools.
- Nonregular types totaled 551 schools, or 12.5%.
- Charter schools represented 3.0% of all operating schools by count.
- Charter schools should not be added to the four type rows because the status overlaps school type.

What the Illinois Education Data Shows
The measures describe system scale, reported staffing, enrollment movement, and public school finance under federal data definitions.
Enrollment movement
Illinois enrollment declined 5.2% from fall 2019 to fall 2024. The annual loss narrowed to 3,383 students between fall 2023 and fall 2024.
School structure
The CCD operating-district count includes all reported LEA types. It should not be treated as a count limited to conventional local school districts.
Spending level
FY2024 current spending covers operating costs and excludes capital outlay, debt service, and non-pre-K–12 programs under the Census definition.
Revenue mix
Local revenue was the largest FY2024 source per pupil. Revenue totals and expenditure totals answer different finance questions and should remain separate.

NCES school and district totals include entities providing services at the start of 2024–25. Student membership includes prekindergarten through grade 13 and excludes adult education students; teachers are full-time equivalents. NCES does not report a 2024–25 U.S. teacher total or pupil-teacher ratio because Tennessee teacher data are unavailable. NCES school type is based on instructional emphasis. Charter is a separate status and can overlap a school type.
Census FY2024 current spending covers operational costs for public pre-K–12 education and excludes capital outlay, debt service, and non-pre-K–12 programs. Dollar values are nominal. Revenue-source shares were calculated from the published per-pupil amounts and may differ by 0.01 percentage point because of rounding.
The 2026 title identifies the publication edition, not a single data year. School structure, membership, and staffing use 2024–25 CCD data; the earlier enrollment trend points remain from the NCES Digest series and the fall 2024 endpoint uses the 2024–25 CCD membership value. Finance uses FY2024 data released in May 2026. The collections use different reporting definitions and should not be merged into an implied statewide total.
Current spending per pupil is a finance indicator, not a direct measure of school quality or student outcomes. The FY2024 position of 11th is based only on nominal current spending per pupil across the 50 states and District of Columbia; it is not adjusted for regional prices, student needs, district structure, or service mix.
