TES allows you to add Course Tags and/or Course Outlines to any course in your own dataset. Course Tags are generally used when there are system-wide or state-approved codes corresponding to courses from that system or state’s institutions. If your system or state has codes that you would like to have added to TES. Provide a list of codes with titles to be added to your account by a CollegeSource staff member. Once the list is added to TES, you can assign Tags to a course.
