Permission to Add (PTA) Numbers

PTA numbers are generated by the academic advising office for the department offering the course you wish to add. Yellow Cluster Advising administers PTA numbers for PSC, PHI, CGS, and STS courses.

When is it appropriate to request a PTA number for PSC, PHI, CGS, or STS courses?

Appropriate
  • You were dropped from the course due to non-payment
  • You were dropped from the course due to an administrative (University) error
  • You wish to enroll in a time-conflicted course (only if the course is open, and you meet the prerequisites)
  • You meet the prerequisites, and it is AFTER the 12th* day of instruction 
Not Appropriate
  • The course is full, and it is BEFORE the 12th* day of instruction
  • You do not meet the prerequisites of a course (open or full)—prerequisite petition is required instead
  • You wish to register for a course concurrently with its prerequisite course—prerequisite petition is required instead
  • It is your 3rd attempt of the course—go to OASIS > Forms & Petitions > Multiple Repeat of a Course

*For Summer Sessions, PTA numbers are issued after the 5th day of instruction


PTA Request Form (PSC, PHI, CGS, STS Courses Only)

In this form, please include:

  • Name
  • Student ID
  • Email
  • Course number and section (PSC, PHI, CGS, STS courses only)
  • Reason for PTA request
  • Copy of an emailed consent from instructor (from their UCD email address)

Why do I need to wait until AFTER the 12th day of instruction to get a PTA number?

Equity and fairness to other students. Waitlists end on the 12th day of instruction. If students use a PTA number before waitlists end, then they skip the waitlist. In our department, we try to avoid this situation in order to be fair to students on the waitlist.

If students add using a PTA number after the 12th day, and the course is full, they can still add the course. This way, those students still get to add the course, while other students on the waitlist get a fair chance at getting into the class as well. 

Note: For Summer Sessions, PTA numbers are issued after the 5th day of instruction, when summer waitlists end.
