Best Independent (non-religious) High Schools

188 schools match. Top 10 ranked by size, tuition fit, and freshness of our data.

We track 188 independent (non-religious) high-level schools across our active markets in Florida and New York. Annual tuition ranges from $8K/yr to $145K/yr, with a median of $49.3K/yr across schools that publish a number. 74 of these schools accept Florida Step Up / FES scholarships — roughly 39% of the list — so families using state-funded scholarships have real choice here.

High-school admissions usually require an ISEE or SSAT, transcripts, two teacher recommendations, and an interview. Application deadlines cluster in November-January for fall entry. Every school is re-verified through direct outreach to admissions teams; data is refreshed on a 180-day cadence and timestamped on each profile.

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We do not publish scoring weights or per-axis thresholds.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.
