How we ranked these

We measured six weighted factors: academic performance via test scores and AP/IB depth (25%), college and post-grad outcomes (20%), value and cost (15%), teacher quality and resources (15%), environment and culture (15%), and extracurriculars and fit (10%). Data came from U.S. News, Niche, Private School Review, and school-reported profiles. Schools with high graduation rates, strong AP catalogs, and proven college matriculation ranked highest.

We deliberately ignored marketing claims, campus aesthetics, and school age, as these do not predict student success. We also excluded single test averages and unverified parent anecdotes. Our focus stayed on measurable outcomes and fit factors that families can verify. This approach avoids rewarding prestige without substance and ensures rankings reflect what actually impacts a student's high school experience and future trajectory.
