How we rank these schools
Built relationships, not scrapers. AdmitCompass ranks schools using a composite score that blends four signals: enrollment size (a proxy for stability and program breadth), tuition reasonableness within the local market, freshness of our most recent verification, and a small bonus for schools with full admissions detail published on their profile.
Public data comes from the Florida Department of Education (FLDOE), the National Center for Education Statistics (NCES), and each school's own admissions pages. The information that actually matters to most families — acceptance rates, deadlines, what a director cares about — comes from direct interviews with school directors and admissions coaches across our active markets.
We do not publish scoring weights or per-axis thresholds. That keeps the moat intact: the rankings reflect actual conversations with people inside schools, not a formula anyone with a crawler could clone. Every profile is re-verified on a 180-day cadence, and the "last updated" date is timestamped on every school page.
