Teachworks records the timestamp when lessons are completed. A lesson is completed when the status of the lesson is changed from "Scheduled" to one of the other statuses (i.e. "Attended", "Missed", or "Cancelled").
There are a few methods that you can use to view the completed at timestamp:
Method 1 - Lesson History
Click on "Calendar" and then click on "Lesson History".
Find the lesson that you want to view and click on the lesson title to view the lesson details.
If the lesson has been completed, there will be a "Completed At" field with the timestamp it was completed in the sidebar.
Method 2 - Lesson History by Student
Click on "Calendar" and then click on "Lesson History by Student".
Find the lesson that you want to view and click on the lesson title to view the lesson details.
If the lesson has been completed, there will be a "Completed At" field with the timestamp it was completed at the bottom of the pop-up.
Method 3 - Lesson History & Lesson History by Student Downloads
From either of the tables mentioned in Method 1 and Method 2 above, you can click on the "Download Lessons" link on the right-hand side to download the lessons to Excel.
The "Completed At" column in the Excel file will display the timestamp when the lessons were completed. This method is useful if you want to view multiple lessons at once.
