Across all NYU schools, international applicants with non-English academic documents must provide certified English translations. For graduate programs, NYU specifies that translations may come from your university, a certified translator, or a NACES member — but the applicant cannot translate their own documents. For undergraduate applicants, the rules are slightly more flexible: translations from a school official or an accredited translation agency in the country of the institution are acceptable.
Beyond the translation itself, most NYU graduate programs require a course-by-course credential evaluation from a NACES-member organization. NYU generally recommends NACES members, but specific schools have preferences — Steinhardt prefers WES, Gallatin requires WES ICAP or ECE submitted with the application, and SPS requires evaluation if more than half of your academic program was at a foreign institution.
An important detail for enrolled undergraduate students: NYU automatically partners with ECE for credential authentication of international high school records. NYU creates the ECE account for you and covers the cost. This happens after enrollment, not during the application — so it does not affect what you submit with your initial application.
