TalentLMS allows you to update course content even if users have already started the course.

Here’s how different updates affect users’ progress:

• You update a unit: Users who have already completed the unit will still see it as completed.
• You delete a unit and create a new one in its place: All users will see the new unit as incomplete.
• You add new content to a course: Users who have already completed the course will still see it as completed. To align users' progress with the updated course material, you need to synchronize their progress. 

To update a unit, follow these steps:

1. Sign in to your TalentLMS account as an Instructor and go to Courses (1).

2. Hover over the course you wish to update and click the Edit button (2) that’ll appear next to it. The course editor page will open.

3. Select the unit or units you want to update and add your new content as needed.

4. To push your course updates to your live environment, point to the updated unit(s), click the vertical ellipsis icon (3), and then select Publish changes (4).
