Spring 2026 Post-Enrollment Requirement Checking (PERC) Anonymous (not verified) Wed, 12/03/2025 - 00:00 Registrar Network

The post-enrollment requirement checking (PERC) process will run in batch for spring according to the schedule below.

As a reminder, PERC gives admin users the ability to see if an enrolled student has met the requirements for a class and, if not, which requirements have not been met. Please note that the PERC process looks at both restrictions (major restrictions, minimum unit restrictions, etc.) and prereqs/coreqs that are set up as requisites on the class.

For more detailed information about using PERC, navigation, using the drop feature via the PERC roster, etc., please see our PERC webpage.

Please note the following:

If you want to drop a student because they do not meet the requirement, you can do so through the deadline to drop without a W notation, but you should try to have these done before the first day of classes when possible. If you drop a student, you are responsible for contacting the student to let them know they've been dropped and why.
For spring, we'll run PERC according to the following schedule:
- Run twice before classes begin – night of Dec. 19 (after grade processing has completed for most fall sessions) and night of Jan. 4, 2026
- Run after first week of classes – night of Jan. 14, 2026
- Run the day after the add deadline for Session B – night of Jan. 17, 2026

Dear [first],

Our records indicate that you expect to complete the undergraduate requirements for your Bachelor's–Accelerated Master's (BAM) program in Spring 2026.

If this is still when you plan to graduate with your bachelor's degree, complete the following steps by Feb. 1, 2026, to continue with your master's degree:

Submit a master's continuation form.
Submit a BAM supplement form to identify which courses you're double counting and which should apply to your master's degree.

If your expected graduation term has changed, please complete a BAM program change form so we can update your records. If you’re completing your bachelor’s degree this semester, you’ll need to complete the steps above by Wednesday, Oct. 1, 2025.

Students are considered for different types and amounts of financial aid when they become graduate students. If you’re receiving financial aid, please note that your aid will be adjusted automatically when your student status changes.

Spring 2026 Advising Hold Changes Due Sept. 4

Spring 2026 Advising Hold Changes Due Sept. 4 Anonymous (not verified) Thu, 08/28/2025 - 00:00 CU-SIS Development Team

Spring 2025 Advising Hold Timeline

Tuesday, Aug. 26: The Business Analytics & Operations team contacted departments with existing holds.
Thursday, Sept. 4:
- Deadline for departments with existing holds to submit additions, changes or deletions.
- Deadline for departments to request a new advising hold (email your request to cusisdev@colorado.edu).
Wednesday, Sept. 10: Deadline for departments to submit SID lists for batch processing (if applicable).
Thursday, Sept. 11: The Business Analytics & Operations team begins setting advising holds.
Wednesday, Oct. 8 at noon: Final advising hold deadline.
Monday, Oct. 13: Assigned Spring 2026 enrollment dates are visible to students in Buff Portal. No new advising holds will be assigned.

We will begin setting Spring 2026 academic advising holds (a.k.a., advising service indicators) for continuing students after fall census and expect to complete that process on Monday, Sept. 22. Once set, these holds will prevent students in those programs from registering until they've met with their academic advisor.

If your department would like to discuss creating a new advising hold for Spring 2026, email the Business Analytics & Operations team with the details of your request by Thursday, Sept. 4.

Review Your Holds

If your department currently uses advising holds, you should have received an email from the Business Analytics & Operations team last week to confirm the population and text of your hold. Reply with any necessary changes, additions or deletions by Thursday, Sept. 4.

If your department's advising holds are assigned using an SID list, submit your list by noon on Wednesday, Sept. 10. Lists submitted after that date will be processed in the order in which they're received, allowing at least two business days for processing.

Notify Your Students

To support student success, academic departments are responsible for notifying their students when an advising hold is placed and for providing a clear explanation of the steps the student must take to have it released.

If you wish to request an e-memo, student communications are distributed by Strategic Relations & Communications using CU Boulder Today and associated campus communication tools. Visit the CU Boulder Today website to view the different tools (e.g., CU Boulder Today stories and administrative e-memos) and submit your message for campus audiences.

Release Holds Promptly

Advising holds include a timeline for release (e.g., "After you've met with your advisor, your hold will be removed within three business days"). Please remove the advising hold as soon as you can after the student has received advising to ensure compliance with this timeline.

For step-by-step instructions for both manual and batch removal, see our advising holds page.

We will be setting Spring 2024 advising holds (a.k.a., advising service indicators) for continuing students on Monday, Sept. 23. Once set, these holds will prevent students in those programs from registering until they've met with their academic advisor.
