Within your class you have the ability to view student progress for activity, lessons, modules, quiz scores, and weekly progress. This will give you a quick snapshot of how students are doing in the class and prompt some questions you may want to ask (ie What students need more help? Do we need to spend more time on a concept?).
The easiest way to access Progress Tracking is to go to the Toolbox at top of any page. You should then go to the Progress section and select which type you'd like to view.
If you select Activity or Lesson Progress, you can see the students and their progress shown with colored bubbles. Gray = not started, Pink = needs work, Yellow = started, Green = completed, Dark Green Circle = passed with teacher review:
Please note that Progress Tracking is a Pro feature and is not available on the free version.
