Most high school students juggle more than one test: the PSAT in the fall, the SAT or ACT, and AP Exams in May. This calendar puts every date you have to plan around in one view, so you can schedule your prep, register on time, and keep tests from landing in the same week.
The College Board gives the Digital SAT on select Saturdays throughout the year. Registration typically closes about two to three weeks before each test date, so early planning is essential. The SAT is offered from August through December in the fall, and again in March, May, and June in the spring.
For a full breakdown of upcoming SAT dates, registration deadlines, test times, and locations, see our SAT Test Dates guide.
ACT, Inc. offers the ACT on seven national test dates per year, with both regular and late registration windows. The test is available in February, April, June, July, September, October, and December. Late registration carries an additional fee, and some test centers (particularly in New York) are not available for every date.
For complete ACT scheduling details, registration deadlines, and fee information, visit our ACT Test Dates 2026 and ACT Test Dates and Registration guides.
AP Exams are given during two weeks in May each year. Unlike the SAT and ACT, AP Exams are on fixed days at fixed times, so you cannot choose your test date. Each subject has a morning or afternoon slot, and students with scheduling conflicts can arrange late testing through their AP coordinator. In 2027, the exams run May 3–7 and May 10–14, with late testing May 17–21.
See the full AP exam schedule in our AP Test Dates 2027 guide.
The PSAT and the PreACT have no national test date. Your school orders the test and picks a day inside the testing window, so the calendar shows each window as a range rather than a single day. The PSAT/NMSQT and PSAT 8/9 window runs October 1–30, 2026, and the PSAT 10 and spring PSAT 8/9 window runs March 1 to April 30, 2027. Ask your school counselor which day your school chose.
