The Interventions graph provides an easy way to identify individual students who may be struggling. The graph, which can be found in the Interventions tab on the Teacher Dashboard, is a relative graph, comparing the students in your class to each other.
The graph plots the amount of time spent on the platform by the students, against their average score. Each student is represented by a dot on the graph. By hovering over a dot in the bottom right quadrant you can identify a student who may need extra support as they are spending the time on CENTURY, but not achieving a high average score.
The students who might also need further attention are those in the bottom left quadrant as they are not spending much time on the platform at all. It may be that these students have forgotten their password or don't have access to a device.
