The summary of the Current Enrollment is located on a Study’s Enrollment page — reached from the “Manage Enrollment” link in the “Enrollment” panel on the Study’s main page. This summary is right below the “New Enrollment” forms.
You can browse or search through your current subjects here and review their progress through the Study. The table lists their unique Subject Codes, their email addresses, their overall status, and timestamps of when they were invited, when they were last reminded, and when they completed the Study. You can remove a Subject from enrollment by the “Remove” link, and you can edit the Subject’s email address and names by clicking the link associated with their subject code.
