About student work in Schoolwork
Student work includes any shared file a student is working on, as well as everything a student submitted to a Handout. Students can submit work in response to an activity you assigned or an item you requested in a Handout.
Students can submit work within Schoolwork, or they can use the Share button to submit from another app. Students can submit items such as app files, collaborative files, spreadsheets, PDFs, photos, videos, or scanned documents. For example, in Keynote for iOS, students can create a file, tap the More button, tap the Share button, tap Schoolwork, then select their class and Handout to submit the file.
Note: Schoolwork displays the work students submit as progress associated with an assigned Handout.
