The Missouri Department of Higher Education has identified a common set of general education courses that have been adopted statewide. These courses are called the “CORE 42.” CORE 42 courses are guaranteed to transfer to any Missouri public college or university to satisfy general education requirements.
Courses in knowledge areas below, designated with the CORE 42 logo indicates courses in that area have been evaluated and provided a MOTR number for transfer to all Missouri public institutions of higher education.
Courses that do not have this designation may still transfer to public and private colleges and universities in Missouri and elsewhere, but students are encouraged to check the transfer equivalency website of the institution to which they plan to transfer to confirm.
Please refer to the MDHE Core Transfer Curriculum for detailed information on CORE 42 courses.
