1. Duplicate and Rename. If you will be using the same assessment for second semester, I recommend duplicating and renaming the assessment. The reason for this is because sometimes students will need to retake a course for the second semester. If that student already has data in the assessment, you'll need to delete it to enter the new stuff. There's a video for duplicating here.
2. Refreshing to Last Semester's Data. If you know for sure that you will not have the same student in the second semester, you will not need to duplicate and rename. In this case, you might want to go back and look at last semester's data in order to compare performance. To do this, use the terms box pictured below to select the term you'd like to use. Next, click the Update button.
