2027 AP Exam Start Times: What Changed and Which Schools Keep 8 a.m. and 12 p.m.

2027 introduces AP start-time changes in some locations

Beginning with the 2027 AP Exam administration, College Board changed start times for exams in some locations to reduce the risk that secure exam content can move across time zones before another group begins testing. This is a scheduling and exam-security change, not a new student scoring rule.

Most U.S. schools keep the familiar times

College Board says that for most schools, including all schools in the lower 48 United States, Hawaii, and Washington, D.C., AP Exams still begin at 8 a.m. local time for Session 1 and 12 p.m. local time for Session 2. Students should still follow the reporting time given by their AP coordinator because schools typically require arrival before the actual exam start.

Why students should not rely on an old screenshot

A schedule image from 2026 or a generic blog may list the old timing without the 2027 location rules. For a high-stakes exam, use the current College Board schedule and the instructions from your school. The date alone is not enough; you need the subject, session, reporting location, and exact arrival time.

Session 1 and Session 2 are better labels than morning and afternoon

College Board's 2027 schedule uses Session 1 and Session 2 because clock times can vary by location. In many U.S. schools those sessions correspond to the familiar morning and noon starts, but the labels avoid implying that every country or territory uses the same local clock time.

Arrival time is not necessarily start time

If the exam begins at 8 a.m., that does not mean students should walk into the room at 8 a.m. Schools need time for attendance, seating, device checks where relevant, distributing materials, and reading instructions. Your AP coordinator determines when students must report. Put that reporting time on your calendar, not just the national session time.

What if your school tells you a different time?

Do not argue from a search result. First confirm that the school is using the official 2027 schedule for its location. AP coordinators receive administration guidance and are responsible for telling students when and where to report. If something looks inconsistent, ask the coordinator to clarify before test day.

Early testing is not an option

College Board states that early testing or testing at times other than the published AP Program schedule is not permitted. Schools cannot move a secure exam earlier simply for convenience. If a legitimate conflict prevents regular testing, the appropriate route may be official late testing rather than an unofficial time change.

Device and digital-exam timing

For digital or hybrid digital AP Exams, students may need to complete device preparation and check-in tasks before the timed exam starts. That makes early arrival especially important. Follow school instructions for Bluebook or any other required testing setup rather than treating 8 a.m. or 12 p.m. as the time to begin device setup.

2027 planning checklist

1. Find your subject on the official 2027 AP schedule.
2. Note whether it is Session 1 or Session 2.
3. Ask the coordinator for the exact local reporting time.
4. Confirm the room and device instructions.
5. Plan transportation with a buffer.
6. If you have two exams in the same session, ask about late testing instead of trying to move one unofficially.

Bottom line for U.S. students

If you attend a school in the lower 48 states, Hawaii, or Washington, D.C., College Board says the normal 8 a.m. and 12 p.m. local start pattern still applies in 2027. The important change is that some other locations now use different timing. Always treat your coordinator's current instructions as the final operational detail for your school.
