What Professors See in a Canvas Quiz Log: When an instructor clicks “View Log” on your Canvas quiz attempt, Canvas displays a chronological timeline of five exact event types: (1) Sessionstarted, (2) Viewed (and possibly read) a question, (3) Answered a question, (4) Stopped viewing the Canvas quiz-taking page (triggered by window.blur), and (5) Resumed. Canvas does not record your screen, webcam, or clipboard text without a separate proctoring tool.
Double-clicking Question 1 on Canvas Quiz Log triggers an inline solve, selects the verified option, and opens the Right-Side Answer Banner.
Every event in /submissions/:id/log explained line by line.
Inside the Professor’s Dashboard
There is massive misinformation online about what Canvas quiz logs actually record. Based on Canvas's open-source canvas-lms repository (quiz_submission_events_controller.rb), here is what instructors see—and how ExamGhost keeps your log spotless:
A viral myth claims that switching tabs for less than 15 seconds won't show up on Canvas. In reality, Canvas flushes its event buffer every 15–60 seconds, but the window.blur listener fires at 0.001 seconds and stores the event in the queue. Only staying inside the tab prevents page_blurred.
In a normal student log, “Viewed (and possibly read) a question” is followed 35 to 90 seconds later by “Answered a question”. Double-clicking one question at a time with ExamGhost produces this exact green-check sequence without a single red focus warning.
Right-clicking a quiz diagram and clicking “Save image as...” opens the OS file dialog, which immediately steals focus from Chrome and logs “Stopped viewing the Canvas quiz-taking page”. Pressing Alt+S crops the diagram inside the viewport with zero OS dialogs.

page_blurred events. Instead, the red “Stopped viewing the Canvas quiz-taking page” warnings are shown to the professor or TA when they manually inspect your quiz log. Keeping zero red warnings ensures your log never raises suspicion during an audit.quiz_submission_events controller does not log copy events by itself, because copying text only helps if you switch tabs to paste it somewhere else (which triggers page_blurred). Furthermore, with ExamGhost you never press Ctrl+C at all—just double-click the question block.window.blur. ExamGhost's Alt+S Snap-It tool crops the image purely inside the browser viewport without opening any OS dialog.quiz_submission_events for the entire duration of the course term (and typically 6 to 12 months in institutional archives). Keeping your log 100% clean from the moment you take the quiz ensures peace of mind all semester.
