Visiting students can begin registering for Summer 2020 courses on April 1, 2020. The schedule for matriculated students will be posted to the bottom of this page in the spring semester.

Registration Limit

The registration limit is 6 credits per summer session. New York State guidelines suggest a maximum of 6 credits during each five-week session or a total of 12 credits during the entire summer.

Registration Requirements

All students registering for courses must meet all financial obligations relating to the registration, be in compliance with the New York State Immunization Law, and meet all the course requirements (prerequisites and other conditions stated in the course schedule) before registering. The University reserves the rights to enforce all regulations related to registration at any time.

Students who have holds on their registration must have them cleared by the registration deadline date in order to register. Course availability will be determined as of the day the hold is cleared, not the day the registration was received (unless received after the hold is cleared). This includes immunization, admissions, academic, and financial holds. No exceptions will be made.

Please Note: New York State Immunization Law requires all students registered for 6 or more credits, born after 1956, to prove immunity to measles, mumps, and rubella. Course registration and attendance at Adelphi University will not be possible without clearance by the Health Services Center.

Register Online

The Course Listing, Advising, and Student Service (CLASS) system on eCampus will allow you to select your courses, notify your adviser, and submit your registration (with adviser’s approval, if needed) at your appointed time.

For more information and instructions, see Undergraduate Online Registration or Graduate Online Registration.
