Online Registration

All registration at Drew University is processed online via our Treehouse system.  After you have reviewed and selected courses and are prepared to register for the Fall term, you may do so via our Treehouse system by following these instructions:

  • Go to
  • Log in using your username and password
  • Under the Registration Tools heading, click on Registration Status

Note: If you do not know your ID and password, please contact the CNS at x3205 (or at 973/408-3205 from off-campus).

Later Changes in Registration

If you find that you need to make changes in your registration (drop/add) after classes begin, you may do so during the first two weeks of classes. During the second week of classes, you may add a new course only with the approval  of the course instructor. You may not enter any new course after September 10th. Courses may be dropped until the end of the ninth week of classes, through November 2nd. Courses dropped during the first two weeks do not appear on a student’s record. Courses dropped from the third through the ninth week are entered on a student’s record. Courses dropped from the third through the ninth week are entered on a student’s record with the notation “W” (withdrawal). After that point, a notation of “F” (Undergraduate) or “U” (Theological unsatisfactory) appears on a student’s record for a dropped course. All of these dates can be found on the CLA Academic Calendar, Theological School Academic Calendar, or Caspersen Academic Calendar.

(Please also review FERPA, the Family Education Rights and Privacy Act (via a link listed in the helpful links area on the left of this page) to understand your access and privacy rights regarding your student records.)

Register for Classes

Once you have selected the courses you wish and noted the CRN # for each course, you are ready to register. No emails are sent by the system to tell you or your advisor what you have registered for. Your preliminary registration will not need the approval of your academic advisor. However, you will be required to meet with your advisor to review your registration when you come on campus for orientation. You and your advisor can see your schedule within Self Service (SSB) – for students, the schedule is within the Registration menu. If you intend to be a full time student for the semester, you need to register for a full schedule excluding waitlisted courses. Waitlisted courses will not be considered when determining your status.

    1. You are already registered for another section of the class.
    2. You have a time conflict with another class.
    3. Your class has a co-requisite which you did not select at the same time.  Co-requisites MUST be added together.
    4. Your class requires “instructor approval”  and the instructor has not yet entered the approval or you have not yet contacted the instructor for approval. You will not be able to register for the class without this approval.

    • If you don’t know the CRNs or want to search for another class, click on “Class Search” at the bottom of the screen.  Details on how to search are provided under “Search for courses for a term”, above.

Once registration is open, the box under “Select” will be displayed and you can check off the box and click “Register” to register for that course section.   If you check the select box and click “Add to WorkSheet”, the course will be added to your worksheet list.  You will not be registered for the class until you “Submit Changes” (from the Register, Add or Drop Classes worksheet page), which will add all of the courses in your worksheet to your registration.
    • If a class is closed but does have openings on the wait list and you want to be placed on the wait list, you need to add the CRN to the Worksheet and “Submit Changes”.  The class will appear in the “Registration Add Errors” until you select “Wait Listed” in the action dropdown menu and “Submit Changes”.  To see your position on the wait list, select the link at the bottom “Student Detail Schedule”.  Under the waitlisted course, you will see the “Waitlist Position”.
