Adelphi University began in Brooklyn in 1896 as Adelphi College and moved to Garden City, New York, in 1929. It became Adelphi University in 1963, reflecting its expansion beyond undergraduate education.
The move established the Long Island campus that remains the university's center. Over time, Adelphi added graduate and professional programs in fields including business, education, nursing, psychology, and social work. That history helps explain its present mix of a residential campus, a large commuting population, and programs serving both traditional-age and adult students.
Adelphi organizes its degree programs across the College of Arts and Sciences, College of Education and Health Sciences, College of Nursing and Public Health, College of Professional and Continuing Studies, Gordon F. Derner School of Psychology, Robert B. Willumstad School of Business, and School of Social Work.
Students can pursue subjects ranging from biology, computer science, English, and the performing arts to accounting, teacher education, nursing, psychology, and social work. The university offers bachelor's, master's, doctoral, and professional programs; availability and admission standards differ by program. The College of Professional and Continuing Studies is particularly relevant to adults exploring flexible pathways, while applicants to clinical and professional programs should examine prerequisites, fieldwork, and licensure requirements separately from general university admission.
The reported student-to-faculty ratio is 11 to 1. That institution-wide figure describes staffing relative to enrollment, not a promise about the size or teaching format of an individual class.
Adelphi's main campus is in Garden City, a Nassau County suburb on Long Island. The setting gives students access to the New York City region without placing the main campus in Manhattan.
The Garden City Long Island Rail Road station and regional roads are relevant to commuters, who make up a substantial share of Adelphi's students. Transit convenience will depend on a student's origin, class schedule, and the connection between the station and campus. John F. Kennedy International Airport is a useful regional airport for students traveling longer distances. Adelphi also offers some programs and services at other New York locations and online, so applicants should confirm where their particular courses and required placements meet.
Adelphi describes its educational mission in terms of personalized learning, intellectual development, and engagement beyond the classroom. Its stated priorities connect liberal arts study with professional preparation, research, creative work, and service.
Those statements express institutional aims rather than independently measured outcomes. A prospective student can assess how they appear in a specific program by looking at advising arrangements, undergraduate research access, internship or clinical requirements, and opportunities to work with faculty. Adelphi is a private, nonsectarian university; applicants do not need to share a religious affiliation to attend.
