42 public K-12 schools in Ann Arbor 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, Ann Arbor has more public-school enrollment than 92% of the 4,487 US cities in this directory. Ann Arbor 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.
Ann Arbor's list includes 20 elementary, 5 middle, and 8 high-school campuses, plus 9 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.
The 66-point gap between Young Adult Programs and Washtenaw Technical Middle College shows the range hidden by Ann Arbor'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.
Ann Arbor school enrollment ranges from 3 students (lowest) to 1,696 students (highest), a spread of 1,693 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 Lower values often correlate with smaller scale and population characteristics rather than higher resource budgets per se.
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.
Young Adult Programs has the highest Resource Investment Index among the Ann Arbor schools in this federal-data comparison at 78/100. The index summarizes reported staffing, counseling, gifted-program, and attendance inputs; it is not an academic rating.

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.
