These courses constitute the Core Transfer Map (CTM), a required component of the degree that must total a minimum of 30 credits.  If the credit total for the selected options is fewer than 30 credits, students must select an additional General Education course to complete the CTM component of the degree.

2

Any 100-level or 200-level credits can satisfy elective requirements for the AST. Each Oregon public university has limits on the number of transfer credits in specific categories of electives (vocational-technical, PE, etc.) that can apply to the bachelor degree; students should work with an advisor to determine their electives based on their transfer plans.
