- Spot unusually high or low scores against available records.
- Keep grade analysis close to the moment grades are posted.
- Surface missing data before drawing conclusions.

Questions about this workflow
Does this calculate a class average automatically?
Notis can calculate it when the relevant scores are available in ClickHouse. If the query needs a course or assignment key that is not available, include the key or data source in your instruction.
Will it change grades in Canvas?
No. The configured ClickHouse action runs a query and returns results; this workflow is for analysis and reporting.
