Contract Credit/Extension Courses
Contract credit is awarded for contracted professional development, as for teacher training when the CSU does not provide the actual instruction but does administer the awarding of credit. Extension courses are one way SSU offers university level academic credit resources to the wider community. The courses offer either academic credits, CEUs, or both.
