timed app activity
An app assigned as a timed task. For example, you can ask your students to choose a story to read in Apple Books for a minimum of 30 minutes.
Classwork only reports progress data for timed app activities when a student opens the app within an assignment, your school turned on the Student Progress feature in Apple School Manager and the app is active (the window is in front). Classwork only reports progress for the time you specified, even if a student uses the app for a longer amount of time.
