Inter-University Doctoral Consortium (IUDC)



The Graduate School is a member of the Inter-University Doctoral Consortium (IUDC), which provides for cross-registration 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.

M.A. students are not eligible for this program.

Ph.D. students in years 2 through 6 register at Columbia for the course(s) they plan to take at the visiting institution by submitting the IUDC Registration Form (PDF). The host institution may also require 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.

Tuition is paid to the Graduate School. Classes may be taken for a grade and 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 (Pass/Fail is an option), not for R credit or Audit.

Registration Period

Students must register between August 26 and September 27 for fall and between January 14 and February 14 for spring.

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

Instructions for Columbia Students Studying at Another University

  1. Complete the “Personal Information” and “Home School Information” sections on the IUDC Registration Form (PDF). After obtaining the signatures of your advisor, bring your form to 107 Low Library for certification that you have completed one year and are within seven years of first registration as a Columbia Ph.D. student.
  2. Complete the “Host School Information” section and obtain the signatures of the Host Instructor and Host School IUDC Coordinator.
  3. Register with the Host School Registrar. See contact information for participating schools on page two of the IUDC Registration Form.
  4. 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.
  5. Set up an email account at the Host School to ensure that you receive information regarding your course at the Host School.
  6. Return a copy of the IUDC Registration Form to 107 Low Library. The form should have all four signatures (Columbia Advisor, Columbia IUDC Coordinator, Host School Instructor, Host School IUDC Coordinator). The Columbia IUDC Coordinator will make a copy of your IUDC Registration Form and will add the IUDC course to your roster of courses at Columbia. You should retain the original registration form until a grade appears on your transcript.

Instructions for Students From Other Universities Studying at Columbia University

  1. Complete the IUDC Registration Form (PDF) and obtain all four signatures (Home School Advisor, Home School IUDC Coordinator, Columbia Instructor, Columbia IUDC Coordinator).

    You must have the signatures of your Home School Advisor and IUDC Coordinator before you get the signature of the Columbia IUDC Coordinator (Thalyana Stathis, 107 Low Library). You may obtain the instructor’s signature whenever is most convenient, but you must have that signature before you register at Columbia. You may register during the general registration period. When signing the form, the Columbia IUDC Coordinator will make a copy of your IUDC Registration Form.

  2. You must complete the University's two immunization requirements at least 30 days prior to registering for classes. You must document your immunity regardless of whether you have provided similar documentation to your home institution. See the Columbia Health website for details.

    Note: Students who have provided documentation of MMR immunity to their home institution’s health service may request that the home institution submit that documentation to Columbia Health on their behalf.

  3. Register with the Columbia Registrar.  The Registrar’s Office is in 205 Kent Hall. You must register in person at the Information Desk in that office. You will be asked to give information about yourself and the course you will be taking. Please have the five-digit call number for the course available (listed in the Columbia Directory of Classes). Note: You may not take courses for R credit.
  4. Set up your Columbia UNI (University Network ID) and email account. You must have a Columbia UNI to log on to Courseworks, which contains information pertaining to your class, and Student Services Online (SSOL), which allows you to check your grades and order transcripts. You must set up a Columbia email address in order to receive announcements and information related to your course.

    To set up your Columbia email address, you must first activate your UNI by completing the following steps. Please note: your UNI will generally be created within 24 hours of your registering for classes.

    • Search for your name in the directory search engine on the Columbia home page.

    • Copy your UNI.
    • Open the "Email" dropdown menu and click on “Manage my UNI.”

    • Click on "Activate UNI or Email."

    • Accept the Account Activation Policies.
    • Paste the UNI as requested.
    • 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.
  5. 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 your UNI has been activated, 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 3-4 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 (also from the ID Center).

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