Go to Students > Assessments > Formative Tracking > Analysis > Average Mark over Time.
The Average Mark over Time analysis is very similar to the Progress over Time analysis, however, instead of showing the average curriculum mastery over time, it shows how the average mark is progressing over time.
The average mark is the average mark a student has only on the curriculum statements that have been assessed. For example, if a curriculum has 10 statements and a student has been assessed on 5 of those; the average mark would be worked out only from the 5 statements which had been assessed.
This allows you to identify periods when the curriculum mastery may have stayed relatively static or has not progressed at a quick enough rate.
With the average mark, you’d want to see it staying relatively high before students start covering new content. A drop in the average mark may indicate that more is being taught and not everything has been grasped fully yet.
