Inter-University Doctoral Consortium (IUDC)

The Graduate School of Arts and Sciences is a member of the Inter-University Doctoral Consortium (IUDC), which provides for cross-registration of graduate-level courses among member institutions. Participating schools are:

CUNY Graduate Center
Fordham University
The New School for Social Research
New York University (including the Institute of Fine Arts)

Princeton University
Rutgers University
Stony Brook University

Teachers College (TC) is also a member of the IUDC, but Columbia students interested in TC classes should cross-register within Columbia rather than use the IUDC.

MA students are not eligible for this program.

PhD students in years two through seven of Arts and Sciences programs (listed under “PhD and DMA programs”) are eligible to participate in IUDC. Students register at Columbia for the course(s) they plan to take at the visiting institution by submitting both the IUDC Registration Form and Columbia’s online IUDC application. The host institution also requires students to register there. Students should familiarize themselves with the academic regulations of the host university, including its location, grading system, applicable deadlines, and calendar.

Classes will appear on the Columbia transcript. Students will receive a letter or ID card allowing them library reading privileges at the host institution. Columbia students going to New York University may use their CUID card.

Courses taken in the IUDC must be taken for a grade or for Pass/Fail, not for R credit or Audit.

Note: IUDC is limited to fall and spring semesters. Summer session or intersession courses are not eligible for the IUDC.

Queries should be directed to the Columbia IUDC Coordinator, Thalyana Stathis, at (212) 854-4738 or ts2980 [at] (GSAS Office of Student Affairs, 107 Low Library).

Registration Deadlines

Columbia students must submit Columbia’s online IUDC application by February 14.

Students from other universities taking Columbia courses must submit Columbia’s online IUDC application by February 14.

Following Columbia’s Academic Calendar, students from other universities must drop courses by February 20.

Instructions for Columbia Students Studying at Another University
  1. Complete the “Personal Information” and “Home School Information” sections on the IUDC Registration Form. After obtaining your advisor’s signature, email your form to ts2980 [at] or bring your form to 107 Low Library to be signed by the Columbia IUDC coordinator. The coordinator will sign the IUDC form within one business day after certifying that you have completed one year and are within seven years of first registration as a Columbia PhD student in an Arts and Sciences program.

  2. Complete the “Host School Information” section and obtain the signatures of the host instructor and host school IUDC coordinator.

  3. Submit Columbia’s online IUDC application by February 14. The online application contains information very similar to that of the paper IUDC form, and you will also upload the paper IUDC form containing all signatures (i.e., Columbia advisor, Columbia IUDC coordinator, host school instructor, and host school IUDC coordinator) to the online application.

  4. Register with the host school registrar. See contact information for participating schools on page two of the IUDC Registration Form.

  5. Obtain an ID card at the host school. You will need to bring either a passport or a state-issued ID. You should check to see if you will need to obtain a semester sticker.

  6. Set up an email account at the host school to ensure that you receive information regarding your course at the host school.

The Columbia IUDC coordinator will inform the Registrar’s Office to add the respective course(s) to your roster of courses on SSOL.

The Columbia IUDC coordinator will inform the Registrar’s Office of students’ grades after the end of the semester. You should retain the original IUDC registration form until a grade appears on your transcript.


Instructions for Students from Other Universities Studying at Columbia University
  1. Confirm that the course you intend to register for is open to the Graduate School of Arts and Sciences. Columbia’s Directory of Classes includes information on courses offered by department or subject, and it should state that the course is “Open to: Graduate School of Arts and Science” on the course’s page in the Directory. Home school IUDC coordinators will inform their students of this policy, and the Columbia IUDC coordinator will also confirm that students are registering for appropriate courses before approving their applications.
  2. Complete the IUDC Registration Form and obtain all signatures except the Columbia IUDC coordinator’s signature (i.e., home school advisor, home school IUDC coordinator, and Columbia instructor) before February 14.
  3. Complete Columbia’s online IUDC application. You must submit Columbia’s online IUDC application by February 14. The online application contains information very similar to that of the paper IUDC form. You will upload the paper IUDC form containing all signatures except the Columbia IUDC coordinator’s signature to the online application.
  4. Please allow four business days for processing. You will receive an email (sent to the email address provided in the online application) confirming that your online application has been approved. The email will outline the next steps to 1) activate your UNI and Columbia email address, and 2) obtain an ID card. 
  5. Set up your Columbia UNI (University Network ID) and email account (if you already have a UNI, you may skip this step):
    Click here.
    Click “Accept” at the bottom of the page.
    Click “Accept” again.
    Instead of entering your UNI, proceed as follows: “Don't know your UNI? Click here to activate.”
    Enter your first and last name exactly as you entered them in the online IUDC form. Enter your date of birth. You do NOT need to enter your Social Security Number.
    Click “Continue” to proceed with account activation.
    Follow the remaining steps to activate your UNI.
    Once your UNI has been activated, you will be prompted to set up your Columbia email account.
  6. View your registration for the approved courses listed on your online application. After activating your UNI, you will be able to view your registration through Student Services Online (SSOL)
  7. Log in to CourseWorks, which contains information pertaining to your course.

  8. Obtain a Columbia ID card, which confers access to the Columbia library system and other services, and allows you access to campus in times of emergency.

    Once you have registered for your course, you must submit a photo online to be used on your Columbia ID card. You will be able to pick up your ID card from the ID Center, which is located just outside the Registrar’s Office in 204 Kent Hall. Please note that it can take up to three to four business days to generate your ID card after you have submitted your photo.

    If you have a Columbia ID card already, you should obtain a semester sticker for that card. Stickers are available at the ID Center.

  9. Follow relevant Columbia policies and deadlines (e.g., for dropping a course or submitting required course materials after the semester has ended to remove an Incomplete).

    NOTE: If you decide to drop your course(s), you must email ts2980 [at] by February 20. 

  10. The Columbia IUDC Coordinator will inform your school of your grade(s) after the end of the semester. You should retain the original registration form until a grade appears on your transcript. You can also log in to Student Services Online (SSOL) to view your grades and order transcripts.
