Teenagers in New York City high schools may need to take five or more of the New York State Education Department (NYSED) Regents Exams in order to graduate with a Regents diploma, but it can be tough to know which schools require the exams, which tests to take, and when students take the exams during their high school career. Every school is a little different, so it’s important to check with the high school counselors and get your school’s exact schedule, but you should be prepared for five exams or more taken over the four years of high school.
