As part of the admissions process we consider the OAT, MCAT, DAT, PCAT and GRE for admission into the optometry program at UMSL. The OAT remains the preferred exam, but we do consider other exams as mentioned.

The OAT is administered online through various testing centers. Visit for more details on the OAT exam.

the OAT test can be retaken every 90 days; students who have taken the OAT more than three times could see an adverse impact on the competiveness of your application.
