OSU Testing Center

The OSU Testing Center is funded through fees collected for administering exams and does not receive funding from tuition or student fees. The OSU Testing Center provides national and local test administration, test proctoring, test scanning for OSU course instructors, and related services. Our mission is to provide high quality testing services following National College Testing Association (NCTA) standards and guidelines.


All individuals who wish to take the ACT Residual at the OSU Testing Center MUST have submitted a current application to OSU before being allowed to register for the exam.  Additionally, the ACT Residual is ONLY available to students unable to take the National ACT on a regularly scheduled test date in time to meet OSU's enrollment deadlines. OSU highly encourages students to take the National ACT over the ACT Residual as scores on the National ACT are accepted by more institutions and scholarships than the ACT Residual.  The ACT Residual CANNOT be used for high school students seeking concurrent enrollment at OSU.
