Tools & Calculators
Free, no-sign-up tools that let you work directly with plainschools's data.
Every tool here runs on the same federal source data behind the rest of plainschools: the NCES Common Core of Data, the Civil Rights Data Collection, and the F-33 school-district finance survey, covering roughly 100,000 public schools and 17,000 districts across all 50 states and DC. The side-by-side comparison surfaces gaps a single profile page hides. Two high schools in neighbouring towns can report nearly identical enrollment yet run very different student-teacher ratios, free-lunch shares, or counselor coverage, and those differences are exactly what a comparison makes visible. Every figure is the raw federal measurement rather than an opinion score, and each tool links back to the underlying record so you can check it; our methodology explains how the data is sourced, computed, and dated. Nothing requires an account or a download, and any schools you select stay in your own browser. Pick a tool below to start working with the numbers directly.
