Undergraduate (Yale College): Expect an application (Common App/Coalition/QuestBridge route), school report and transcript, recommendations, and Yale’s writing supplements; if required for your background, you may also need English proficiency testing results. Yale also notes the $80 application fee (or an approved fee waiver) as part of the process.
Graduate (varies by school/program): Many Yale graduate applications commonly require transcripts, letters of recommendation, a statement of purpose/personal statement, and a CV/resume; standardized tests and English tests can be program-dependent (Yale Graduate School notes TOEFL/IELTS may be needed for some non-native English speakers). In the Yale scholarship-recipient story, Gul Saeed mentions drafting her statements “several weeks before deadlines” and getting feedback from mentors and her advisor, so plan for multiple document revisions, not just one final upload.
