What is the relative importance of disciplinary background, grade point average, GRE score, letters of recommendation, etc?
All of these factors are important, but a good score on one of them can compensate for a weak showing on some other factor. We do not issue cut-off scores, except for the Test of English as a Foreign Language (TOEFL), where a minimum of 550 is required (600 for those interested in a Teacher of English to Speakers of Other Languages (TESOL) certificate).
