Hi, Natasha-

Your class's progress can be found on your class page. Click on your name in the top right corner > Click on Teacher dashboard > Click on your class name, and there is a sidebar on the left with options to view Course Mastery progress or assignment scores.

You can see a detailed explanation of how to view and filter performance and progress in this article: https://support.khanacademy.org/hc/en-us/articles/360031129891-How-do-I-view-my-students-performance-and-progress-

I hope this helps!
