What the NCES Data Says About Missouri Schools
Missouri operates 2,321 public K-12 schools organised into 558 independent school districts serving 887,264 students, per the National Center for Education Statistics Common Core of Data 2024-25. The largest district, Springfield R-Xii, enrolls 22,937 pupils across 57 schools at $13,404 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 12.9:1, a useful benchmark for comparing any individual district or school on PlainSchools. Free-lunch eligibility averages 46.1% across Missouri 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.

Federal data — no proprietary formula.
PlainSchools publishes the actual federal survey data — enrollment, staffing, finance, and demographics from NCES — without a composite rating on top. The insights below are computed directly from those datasets; every number traces to a cited source.
Missouri per-pupil spending varies 3.7× across districts
Per-pupil spending in Missouri ranges from $8,641 (lowest district) to $31,647 (highest), a spread of $23,006. That relatively narrow ratio reflects an unusually equalised funding system — most states have wider gaps. 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.
Missouri operates 558 school districts — among the most fragmented K-12 governance structures in the country
Each district has independent budgeting, hiring, and curriculum authority. The fragmentation predates modern county-level consolidation efforts and reflects 19th-century township governance patterns — a feature of states that organised public schooling around small civic units rather than centralised state systems. Per-pupil spending and accountability variations are largest in fragmented states because each district sets its own tax rate, contracts, and programme mix without state-level coordination above the regulatory floor.
Average Missouri student-teacher ratio is 12.9:1 — low (typically associated with smaller schools or state-funded class-size reduction)
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. Lower ratios in this state often correlate with smaller per-school enrollments and rural geography rather than higher staffing budgets per se. Class-load comparisons are most meaningful at the district or school level, not the state aggregate.
