What Makes a Private School "Competitive"?

Top private high schools share several defining traits:

  • Low Acceptance Rates (as low as 12–18%)

  • Ivy League Feeder Status

  • High SAT/ACT Averages

  • Extensive AP/IB Offerings

  • Exceptional Faculty-to-Student Ratios

  • Robust Extracurriculars & Global Programs

Many of these schools also require SSAT or ISEE scores, interviews, essays, and demonstrated interest through campus visits or virtual info sessions.


How to Get Into a Top Private High School

If you're aiming for a school on this list, here are key steps to take:

  1. Start Early – Begin prep in 6th or 7th grade.

  2. Excel Academically – Grades, course rigor, and teacher recommendations matter.

  3. Score High on the SSAT or ISEE – 85th percentile or higher is typical.

  4. Show Character & Leadership – Schools value well-rounded applicants.

Craft a Strong Application – Personal essays, interviews, and portfolios should tell your story.
