Adelphi University is test optional, meaning applicants are not required to submit standardized test scores for admission. However, they do not allow self reporting of scores, indicating that if students choose to submit scores, they need to provide official results directly from the testing agency. Currently, 23% of applicants submit SAT scores and 3% submit ACT scores; the combined submission rate is 26%, which suggests some students are submitting SAT scores only, as the percentage does not exceed 100%.
