Spring 2025 PhD Enrollment Guide
Spring 2025 Pre-Enrollment
Spring 2025 Regular Enrollment
The published Spring 2025 Class roster lists our officially confirmed courses at Cornell Tech. As a Cornell Tech student, you will only be able to enroll in classes hosted by our campus programs at Cornell Tech and approved Ithaca classes. Ithaca classes not mentioned in the class list below are not open for enrollment.
- When reviewing the class roster, filter by Location for “Cornell Tech” to review your eligible Cornell Tech class offerings.
- Please be mindful that eligible PhD Classes (either hosted at CT or hosted from Ithaca), will have a specific enrollment section for CT PhD students (this is often labeled as LEC 030, 031, SEM 130, 131, and so on).
- CT PhD Students cannot enroll in the Ithaca section of a course offering (often labeled as LEC 001, 002, and so on) as that section is just for Ithaca student enrollment. It is important that you search for available courses using the class roster “Location for “Cornell Tech” filter to avoid confusion as it filters out the Ithaca sections!
- A limited amount of seats across all Master’s Technical courses will be available for PhD enrollment. If you are not able to sign up due to seats being filled, waitlists will open during Reg Enroll in January.
- Within the Class Roster, please make sure to review the notes of the courses you are interested in, as it will indicate if you are eligible to enroll in the class based on your academic program.
- Class meeting patterns, times, grading basis, prerequisites, etc. are official and published.
- Please review your Student Center for any existing holds which may impact your enrollment ability (i.e. Bursar holds, Clinic holds, etc)
- As of now, students will begin seeing a Spring 2025 Term Checklist task in your To-Do List in Student Center. This task will stay active until it is completed.

Enrollment Frequently Asked Questions
Where do I enroll in classes? Are there guides to help me navigate the enrollment process?
Yes, students enroll in classes through Student Center.
- For instructions on how to add, drop or swap classes please click here for a helpful guide! You will be able to add classes to your shopping cart now in preparation for the Regular Enrollment period!
The Office of the Registrar also has Class Enrollment FAQ page that provides additional helpful tidbits on navigating course enrollment.
Can I add classes to my shopping cart prior to the enrollment period?
Yes, classes can be added to your shopping cart prior to when the enrollment period begins. However, this does not save you a spot in the class or guarantee that you will be able to take the class. Once your enrollment period begins, make sure you complete all steps to finish enrolling.
Any classes you add to your shopping cart (Step 1 on Student Center) will remain there during your enrollment or add/drop period unless all three enrollment steps are completed. You are not enrolled or entitled to a spot in a class if it has only been added to your shopping cart. If you are ready to add the class to your schedule, make sure you finish enrolling (Step 3 on Student Center).
What course prefix should I enroll in for a crosslisted course? (This is applicable to Master's Technical Courses)
Some classes are cross-listed across different major disciplines. If you are trying to enroll in a cross-listed Master’s class, please make sure you enroll in the parent section of the class as this is where we saved PhD seats in.
Course Number | Course Name | Parent Section | |
CS 5304/INFO 5304 | Data Science in the Wild | CS: PhDs seats saved | |
CS 5342/INFO 5320 | Trust & Safety | CS: PhDs seats saved | |
ORIE 5213/INFO 5213 | Discrete Optimization | ORIE: PhDs seats saved | |
ORIE 5751/CS 5726 | Applied Casual Inference | ORIE: PhDs seats saved | |
ECE 5260/ ORIE 5735/ ECE 7260 | Graph Data Science | ECE 7260: PhDs seats saved | |
ECE 5545/CS 5775 | ML Hardware and Systems | ECE: PhDs seats saved |
When will waitlists open? (This is applicable to Master's Technical Courses)
Waitlists for Master’s courses will be open for Regular Enrollment.
During this time is when Johnson Registrar (MBA classes), and the Student & Academic Affairs Team begins reviewing available seats to move students off the waitlist. As this is a manual process so we appreciate your patience as we work through this system. Students will be notified IF and WHEN they are officially moved off the waitlist to enrolled in the course during Regular Enrollment via email.
I received this error message: "You are unable to enroll in the class at this time. Available seats are reserved.." What does this mean and what should I do next?
Classes will have a limited number of seats available for specific populations of students based on their major (I.e. INFO, CS, ECE, etc). All of Cornell Tech courses will have these reserved seats set up to allow an equitable distribution of student majors to enroll in a course.
If you encounter this error message, this means all seats have been filled by other students in your group (PhD). Even if the class shows as open/seats available, please be mindful the seats are for other populations.
You will need to either check back later during Pre-Enrollment for a seat to open, or wait until Regular Enrollment to add yourself to the waitlist.
Why does a class appear as open/have available seats but I can't enroll in it? (This is most applicable to Master's Technical Courses)
All Master’s courses at Cornell Tech will have reserve capacity groups arranged as mentioned in the question above. Once a class has reached maximum enrollment for a specific reserve group, it will no longer allow enrollment for students from that group into the class.
If seats are open for other student’s majors, you will still see the course’s status listed with a green circle as “open”. Please be mindful you will still not be able to enroll until a spot becomes available based on your major. Again, if you cannot secure a seat, please try to sign up via the waitlist as well!

I am trying to enroll in a class but there is a time conflict error. What do I do?
Students are not able to enroll in classes that have overlapping time meeting patterns (this will occur if it’s a 15 minute overlap or for the entire meeting pattern). You must decide which class to enroll in for consideration. Students cannot take two classes at the same time (i.e. if you are trying to take an online remote class and an in person Tech class). All classes are taught synchronously so please ensure that you plan accordingly.
How do I sign up for an independent study?
Cornell Tech PhD student’s independent studies are managed through their Ithaca academic field. If you need guidance on this process please contact our team at studentaffairs@tech.cornell.edu.
Once approved by your department, please contact our team and we will enroll you in the independent study. Students cannot self-enroll in independent studies.
Can I enroll in MBA, LAW, TECH, or TECHIE courses?
PhD Students can only enroll in Technical courses – this is under the prefix INFO, ORIE, ECE, and CS.
How do I check my Registration Status?
To check your registration status, log in to Student Essentials and view your “Registration Status” at the top of the page.
- If you are registered, your Registration Status will state “Registered” with a green checkmark.
- The absence of a green checkmark means there is a hold preventing your registration.
Please also review the Class Enrollment FAQ’s as this will provide answers how to use the Registration System (Student Center) along with other helpful tidbits!
How do I see if I have a Hold on my account?
There are several different types of holds – some are informational and must be completed for graduation, and some are immediate and prevent current semester registration. Your Holds are listed at the top right of the page when logged in to Student Essentials. Click on “more information” for complete details including steps to resolve a hold.
As of now, students will begin seeing a Spring 2025 Term Checklist task in your To-Do List in Student Center. This task will stay active until it is completed.
