To be admitted to a campus as a first time freshman, an applicant who has not attended for at least three years an educational institution at the secondary level or beyond where English is the principal language of instruction must receive a minimum score of 500 on the Test of English as a Foreign Language (TOEFL). Appropriate campus authority may prescribe a higher minimum score, based on such campus factors as the nature of the instruction offered, availability of instruction in English as a second language, student enrollment demand, and availability of funds. Achieving the minimum score shall be evidence of the applicant's English competency at a level which will allow the applicant to participate satisfactorily in and benefit from university study. Exceptions may be granted by the appropriate campus authority when there is convincing evidence that the applicant's competence in English is at a level which will allow satisfactory participation in and benefit from university study.
