TL;DR
School workload thresholds help identify crowded days and weeks. Set them consistently with how teachers classify tasks.
Steps
Open General in Insights and the workload-thresholds card.
With administrator access, edit the daily and weekly thresholds.
Review any grade-level overrides and the level source used by the school.
Save and check workload for representative students and dates.
Do not assume a universal default is right for every school. These indicators depend on recorded task workload and do not measure each student's actual hours. Agree on task-level conventions and interpret warnings with teachers.
