Does Thacher offer financial aid?
Families apply through the Clarity Application, and the school runs it alongside admission with a different deadline. A $65 submission fee is due at the end, and Clarity automatically determines fee waiver eligibility from income and assets. International students are welcome to apply for need-based aid. Aid is need-based only, with no merit scholarships, and does not cover living expenses. The $65 fee has no automatic waivers for international families.
Does need affect admission?
Thacher is not need blind, but says it aims to accept students on their own qualifications without regard to their family's financial resources.
