To be considered for the graduate program, you should be near completion or have completed at least a Bachelor of Science degree in chemistry or in a closely related field. Students generally must have earned a B average (3.0 out of 4.0 or equivalent) during their undergraduate and prior graduate work to gain regular admittance. Transcripts from international students that earned a three-year BS degree will be evaluated internally for equivalence to a US four-year BS degree. In most cases, students in these situations may be best served by earning an MS degree prior to entering the Ph.D. program.

Applicants are also required to take the GRE exam. A total combined score of 300 on the Verbal and Quantitative portions of the GRE is required for regular admission. The Analytical Writing score is considered as well when making admission decisions, but no minimum value is required.

In special cases, students who meet the minimum required GPA or GRE score, but not both, may be admitted under a ''Permission to Continue'' clause (PTC). In that case, a condition will be imposed on the admission, typically requiring to maintain a 3.0 GPA or better in the first 12 credit of graduate work at UA.

International students will also generally be requested to provide a certification of English language proficiency (e.g. TOEFL, IELTS). For the TOEFL test, we look for a minimum score of 79, for the IELTS test, a minimum score of 6.5. Students with lower scores may be admitted through ''conditional admission'', in which case they will be enrolled in English as a second language classes on our campus according to their level of language proficiency.
