Eligibility to Enroll in Credit Courses

Nondegree Application Requirements

You need a high school diploma or high school equivalency diploma to enroll in credit courses. If you are under 23 years of age as of Sept. 15 for fall or Jan. 15 for spring, and not officially admitted or enrolled in a CU Boulder degree program, you must submit unofficial copies of either your high school equivalency scores or your high school transcript for review. High school transcripts must include the degree conferral date and must show that you completed your high school degree with at least a 2.0 GPA. Please upload your unofficial documents with your online application. For questions, please email ceregistration@colorado.edu.

Course Restrictions and Prerequisites

Some courses at CU—including mathematics, engineering, language and all graduate-level courses—may be restricted. Proof of completed prerequisites or departmental permission may be required to enroll. If you believe you meet the prerequisite from an outside university or have additional questions about prerequisite approvals, please connect with a CE advisor by scheduling an appointment or emailing ceadvise@colorado.edu.

Holds and Academic Status

A hold on your account (financial, academic, student conduct, etc.) may prevent you from being eligible to enroll. Students should contact a Continuing Education academic advisor with questions about academic probation/suspension/dismissal from the Boulder campus. More about probation and suspension.

Buff Portal and IdentiKey

Buff Portal is the online campus portal and an important tool. It gives you access to credit course enrollment, your CU student email account, campus announcements, semester schedule, tuition bill, book lists, clicker registration, Canvas, and your final grades. Learn more about Buff Portal.

You’ll need an Identikey, or a unique username, to log in to and access Buff Portal. An Identikey allows you to register for CU courses and provides you with access to online services and campus computing facilities. Use your student identification number to activate your IdentiKey at identikey.colorado.edu.

If you have questions, contact us at ceregistration@colorado.edu or 303-492-5148.

Consenting to Do Business Electronically

When you log in to Buff Portal for the first time, you’ll be asked to consent to conduct business electronically at CU. If you don’t consent, you’ll lose access to the portal and instead receive information about how to conduct your official university business offline.

If you have questions, contact us at ceregistration@colorado.edu or 303-492-5148.
