Occasionally, circumstances may make it necessary for an individual student or a group of students to test late. Only students affected by these circumstances may test late. Regularly scheduled exams can’t be used for late testing. For late testing, the College Board develops alternate forms of each exam. All students who participate in late testing at a given school must take these alternate exams on the scheduled late-testing dates at the scheduled times. Early testing isn’t permitted under any circumstances. If a school fails to follow AP security procedures and doesn’t administer the alternate exams on the specified dates at the specified times, scores for those exams are canceled.
