Beanstack includes a "Readers with Flagged Log Entries Report" that teachers can use for their own students only and school managers can use for the whole student and staff population.
The teacher's report screen looks like:
When a teacher clicks on Readers with Flagged Logged Entries Report, they will get a list of students in their own classes who have logged high amounts. If a school manager clicks it, they will get the whole school's list.
