Admissions
Adelphi University accepts 66% of applicants, which makes it accessible to most students who meet the baseline requirements. 19,705 students applied, a pool deep enough to make the acceptance rate meaningful. Only 10% of admitted students enroll — the great majority of admits go elsewhere or nowhere. The score bands below rest on the 14% of enrolled first-years who submitted an SAT score — a self-selected group, and not a cutoff.

A 67% six-year graduation rate is the strongest academic signal on this page. First-year retention of 83% shows the cohort holds together through the hardest year. The two rates sit near each other: few students who return for a second year are missing from the six-year completion figure. Transfer-out runs to 24% — common enough at this school that the completion rate is measuring a smaller group than the entering class. The 12:1 student-faculty ratio is small enough that seminar-sized classes are the norm.
Financial Aid
IPEDS Student Financial Aid · 2023-24 · grant and loan rates against 5,077 degree- or certificate-seeking undergraduates
Students pay $31,303 a year on average after aid, a premium price that the earnings data has to justify. The income table below is the number that matters — $24,095 at $0–30k versus $35,672 at $110k+. Grant aid is widespread — 93% of students receive it, averaging $28,490. Borrowing is widespread: 59% take federal loans.
Entering first-year students
A different, smaller group than the rates above: full-time students in their first year of college anywhere. The grant series here also excludes the "other sources" counted in the all-undergraduate figure, so the two are not comparable.

Net price by family income
The same students as the headline above, limited to those who received Title IV federal aid — a narrower group, with a lower overall average. IPEDS publishes no combined figure across these bands, so they should not be averaged into one.

|---|---|
| $0–30k | $24,095 |
| $30–48k | $24,700 |
| $48–75k | $28,681 |
