Upon completion of Honours Kinesiology I (including KINESIOL 1A03, 1AA3, 1C03, 1E03, 1F03), students whose C.A. is between 5.5 and 5.9 may register in Level II Honours Kinesiology program but will be placed on program probation for one reviewing period. A student may be on program probation only once, and, therefore, by the next academic review must raise their C.A. to at least 6.0 to continue in the Honours Kinesiology program.
Upon completion of Honours Kinesiology I, students whose C.A. is between 3.5 and 5.4 and/or who have failed to successfully complete each of KINESIOL 1A03, 1AA3, 1C03, 1E03, 1F03 may register in Level II Kinesiology General and, may take the Level II Kinesiology required courses for which the prerequisites have been met. Such students must attend a mandatory preregistration counselling session with an Academic Advisor. Eligibility to transfer to Honours Kinesiology at the next review will require a C.A. of at least 6.0 and successful completion of KINESIOL 1A03, 1AA3, 1C03, 1E03, 1F03. Students who fail to meet the minimum requirements must transfer to a non-Kinesiology program for which they qualify.
