Adelphi University operates on a rolling admissions basis for most undergraduate programs, allowing applications to be submitted anytime within the priority deadlines. Fall semester priority deadlines are typically February 1 for freshmen and April 1 for transfers. Spring semester deadlines are usually December 1.
Graduate programs have varying deadlines, often between January and June for fall intake and October for spring. Some programs may have earlier or specific dates, so checking the department’s requirements is essential. International students should apply at least three months prior to the deadline to accommodate visa processing.
