21 public K-12 schools in Gary from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
According to NCES CCD 2024-25, Gary has more public-school enrollment than 83% of the 4,487 US cities in this directory. Gary's average Resource Investment Index falls in the lower portion of the 4,487-city comparison set. The index is a resource snapshot, not an academic grade: it reflects the federal staffing, counselor, gifted-program, and attendance fields available for local campuses. The most useful next step is to open the individual schools below and identify which component is pulling each score down, because the same city average can hide very different campus-level constraints.
A full K–12 ladder sits inside the city boundary
Gary's list includes 8 elementary, 2 middle, and 4 high-school campuses, plus 7 combined-grade records. The city average spans every major grade stage, so the ranked table is more informative when read within level than as one interchangeable queue.
Economic need crosses separate district systems
86.0% of enrollment in reporting Gary schools is eligible for free lunch, while the city list spans 10 districts. That pairing makes a citywide average especially easy to misread: the need measure follows students, but staffing decisions, calendars, program rules, and federal allocations are administered through separate district structures. The 36-point gap between Calumet New Tech High School and Daniel Hale Williams Elem Sch shows how much reported resource capacity can vary inside the same municipal label. Compare schools within the same district first, then use the city view to see how those local systems differ.

Gary school enrollment varies 27× across entities
Gary school enrollment ranges from 45 students (lowest) to 1,232 students (highest), a spread of 1,187 students. That spread is wider than typical and predicts noticeable gaps in service quality between the highest and lowest areas. 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.
The reported share is at least 75%, indicating a high concentration of measured economic need. Title I operates under the Every Student Succeeds Act (ESSA, 2015), but its statutory allocation uses additional LEA-level counts and rules not represented by this average. This percentage is an economic-need context measure; it does not establish a Title I award, show dollars received, or describe how funds are distributed among campuses.
Gary operates 10 school districts — one of the single most fragmented governance structures in the country
Each school district has independent budgeting, hiring, and service delivery authority, and the sheer count here puts it in the extreme tail of fragmentation nationally. 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.
Gary student-teacher ratio is 17.4:1 — near the typical range (US average ~15.7) — citywide staffing is neither unusually lean nor unusually crowded by this measure
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 Variation between sub-units within Gary is typically wider than the Gary-aggregate figure suggests.
38% of the city's listed public-school campuses are reported as charter schools in NCES CCD. Charter status identifies a different governance arrangement; it does not establish admissions availability, academic quality, or the share of city students enrolled in those campuses. Open each school record to compare enrollment and staffing directly.
Most racially and ethnically mixed schools in Gary
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.

How many schools are in Gary, IN? ▼
Gary has 21 public schools with a total enrollment of 11,157 students. 8 are charter schools. Average student-teacher ratio: 17.4:1.
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. See the guide to understanding NCES data.
