Does AP Classroom use a lockdown browser? not for practice — but the real exam does.
AP Classroom Progress Checks run in a normal browser with no lockdown. The locked-down environment you are picturing is Bluebook — the app that delivers the actual digital AP Exam. Here is the difference, and what each one can and cannot see.
The short answer
When students search for an AP Classroom lockdown browser, they usually mean one of two different systems. AP Classroom itself does not use a lockdown browser. Progress Checks, practice questions, and assignments all run in a standard browser tab — you can open other tabs, and nothing forces full-screen or blocks your apps.
The locked-down experience is the digital AP Exam, which is delivered through Bluebook, the College Board secure testing app. That is the part that takes over your screen.
AP Classroom vs. Bluebook
What this means for you
During practice, integrity is enforced socially, not technically. There is no lockdown browser to defeat — but switching tabs is still recorded as a focus-loss flag, so your teacher can see it.
During the real exam, do not try to leave Bluebook. The shortcuts a lockdown would catch are the same gaps that sink you on exam day, so the honest path through practice is also the strategic one. Read our integrity stance →
Frequently asked questions
Quick answers — written by humans, not a chatbot.
Does AP Classroom lock my screen during a Progress Check?
No. Progress Checks run in a standard browser. Nothing forces full-screen or blocks other apps. The platform still logs paste events and window focus, so your teacher can see if you leave the tab.
What lockdown browser does the AP Exam use?
The digital AP Exam is delivered through Bluebook, the College Board secure testing app. It runs full-screen, restricts other apps, and monitors for switching away. It is not a third-party tool like Respondus.
Can my school add its own lockdown browser to AP Classroom?
Yes. Some schools layer their own proctoring — Respondus, a lockdown browser, or GoGuardian — on top of AP Classroom for in-class tests. That is a school choice, not part of AP Classroom itself.
