Have good grades in high school. According to Seton Hall's Office of Admissions, the average student had an grade point average (GPA) between 3.0 and 3.5. While Seton Hall considers other factors besides grades, solid grades demonstrate an applicant is ready for college.
Take the Scholastic Aptitude Test (SAT) or the American College Testing (ACT) exam. Seton Hall University requires either one for admission with an average range of 1600 to 1700 for the SAT and an average of 23 to 25 for the ACT.
Fill out the Seton Hall University application online. While the office of admissions still accepts a paper and pen application, US News and World Reports recommends that if your handwriting is negligible on the application, it jeopardizes your chance of admission.
Have an enthusiastic teacher, coach or director and guidance counselor write a letter of recommendation for you. While you may not have a choice with your school's guidance counselor, US News and World Reports recommends that you chose a teacher who knows your strengths and isn't lukewarm about his feelings.
