Take some time to look over the information.

The College welcomes new students into the program each fall. Because admission is competitive and enrollment limited, it is essential that students complete their applications by the February 15 deadline. Applications received after the class is full will be put on a waitlist, and the Admissions Committee will evaluate them if openings in the class occur. Applicants will receive an admissions decision four to six weeks after February 15.

STEP 3: Submit application materials

Submit all application requirements during the application or email separately to You can also mail official transcripts and materials to Prescott College, Office of Admissions 220 Grove Avenue, Prescott, Arizona, 86301. Official transcripts can be submitted electronically by the issuing institution via Scrip-Safe . Please ask if your college/university offers this service.

International Students

Applications from international students are always welcome. International students whose native language is not English must exhibit a competency in the English language, with a TOEFL (Test of English as a Foreign Language) score of at least 550 on the Paper-based Test (PBT) or at least 80 on the Internet-Based Test (iBT) exam.

Please note that achieving the minimum TOEFL score requirement does not guarantee entrance to the graduate program.

Accepted international students must demonstrate ability to meet educational expenses while studying at Prescott College for the first year. This is called "financial certification." (Students living in Canada and Mexico are also required to document financial certification.) This is the same standard that consular and Citizenship and Immigration Services (CIS) officers will use to determine a student’s financial stability. Students should anticipate that they will be required to present documentary evidence of financial support at the time they apply for a visa and again to the CIS when they arrive in the United States. Funds may come from any dependable source, including scholarships, fellowships, sponsoring agencies, personal funds, or funds from the student’s family. Documentation of personal or family funds should be on bank letterhead stationery, or in the form of legally binding affidavit from CIS. It is wise to get several sets of original financial documents.

International applicants must submit official transcripts translated into English to Admissions. International applicants are also required to have non-U.S. school transcripts evaluated by a professional credential evaluation service. The applicant is responsible for all costs associated with this service. Applicants will need to provide Admissions with a general report or basic statement of comparability.
