Regents exams are administered at the student's high school. Test dates are typically in January, June, and August, although not all schools offer the August tests. Most students take Regents Exams in June of their sophomore and junior years. If a student does not pass a Regents Exam, he or she may retake that exam as many times as needed. For example, a student who fails the U.S. History exam in June of their junior year may take the exam again that August. However, if this exam is not offered in his area in August, he or she must wait until January of their senior year to retake the exam.
