You are welcome to cross-register into Harvard Kennedy School classes if you are a student at Harvard University, MIT, or the Fletcher School of Law and Diplomacy at Tufts University.


Fall 2023 HKS building access and ID cards

All students are required to hold a Harvard University ID (HUID) card to access the HKS campus buildings. Cross-registrants may enter using the main Wexner entrance, off the HKS Courtyard. Details about building access is available on the Keep HKS Healthy page.

Students must submit their cross-registration petition at least 24 hours prior to being allowed in the HKS buildings. Harvard University cross-registrants may access the HKS campus using their student issued HUID card. MIT and Fletcher School of Law and Diplomacy at Tufts University students who have submitted their cross-registration petition may pick up an HUID card directly from the Harvard University ID Card Services Office at the Smith Campus Center, 8th Floor.

Students may provide official government-issued identification for HKS building access if they do not yet have an HUID card.

Only currently enrolled Harvard students, Harvard employees, and Harvard fellows may be auditors due to building access policies. You must have an active Harvard University identification card (HUID) and follow the University’s COVID-19 policies and protocols. Individuals outside Harvard University are not permitted to audit courses for the 2023-2024 academic year.

If you are a student interested in auditing a course at Harvard Kennedy School, you will need to contact the faculty member or faculty assistant for the course and request permission. Once your request is approved, the faculty member or faculty assistant will grant you "guest" access to the Canvas course platform. Audited courses may not be taken for credit and may not be converted into credit for use toward a degree at a future point.

Students may not re-take an audited class for credit.


Disability Accommodations

Harvard University is inclusive of individuals with disabilities (including those with mental health and chronic health conditions) participating in its courses, programs, and activities.  To request accommodations or ask questions about the accessibility of a cross-registered course at or through Harvard, please contact the Harvard disability services office at the school where the course takes place (HOST School) and coordinate with the disability services office where you are currently receiving services (HOME School) in advance of the start of your course.
