Admissions Chances

Stony Brook University is one of the most selective schools in the State University of New York (SUNY) system. Most admitted students have grades and standardized test scores that are well above average. However, Stony Brook has a holistic admissions process involving other factors beyond your grades and test scores. The Stony Brook admissions folks will be looking at the rigor of your high school courses, and not simply your grades. Success in challenging college preparatory classes such as International Baccalaureate, Advanced Placement, and Honors can strengthen an application significantly. At a minimum, Stony Brook applicants should have completed a core curriculum that includes adequate science, math, English, foreign language, and social science classes. Stony Brook will also be interested in seeing an upward trend in your grades during high school.

The university accepts the Common Application, SUNY Application, and Coalition Application. Whichever application you choose to apply, you'll need to write a strong application essay. The university is also interested in learning about your extracurricular activities, particularly leadership and talent related to non-academic pursuits. Finally, all applicants must submit a letter of recommendation. Keep in mind that applicants to the Honors College and a few other specialized programs will have additional application requirements.

In the graph above, the blue and green dots represent accepted students. The majority of successful applicants had a high school average of "B+" or better, combined SAT scores of 1150 or higher (ERW+M), and ACT composite scores of 24 or better. An "A" average and an SAT score over 1200 gives you an excellent chance of receiving an acceptance letter from Stony Brook. Note that there are some red dots (rejected students) and yellow dots (waitlisted students) mixed in with the green and blue in the middle of the graph. Some students with grades and test scores that were on target for Stony Brook University did not gain admission. On the flip side, note that a few students were accepted with test scores and grades a bit below the norm. This is because Stony Brook's admissions process is based on more than numerical data.
