Active UMass Lowell students can log in to SiS to register for courses. Students should check their enrollment appointment date to determine when they are eligible to register.

If a class is full and a waitlist is available, students may add themselves to the waitlist. We recommend enrolling in another course in case a seat does not become available. Please note that if you enroll in an open section of the same course while remaining on the waitlist for another section, you must use the swap function in SIS. Otherwise, your enrollment in the waitlisted section will not process if a seat opens up.

Permission Numbers

Permission numbers are generally obtained directly from the faculty member teaching the course. Faculty contact information is available in the UMass Lowell directory.

A permission number may allow a student to:

  • Register for a course when the required prerequisite is not listed on the student’s SiS transcript.
  • Register for a course with a required co-requisite without enrolling in the co-requisite course at the same time.
  • Register for a course that requires instructor consent.
  • Register for a graduate-level course as an undergraduate student.
  • Register for a day-section or graduate course as a degree-seeking Graduate, Online and Professional Studies (GPS) student.

A permission number does not override the following requirements or restrictions. It will NOT allow a student to:

  • Register for a course while a hold is on the account.
  • Register for a closed course.
  • Register for a course after the applicable add/drop deadline.
  • Register for courses with overlapping meeting times. Students may not enroll in courses with a time conflict under any circumstances.
  • Register if they are not an active student at UMass Lowell.
