A “W” status in the single student search does not necessarily mean that the student has withdrawn from the institution. It can mean the student was enrolled, but did not return for an additional term. Whenever you see a “W” status, you should compare the status first started and term end dates. If the dates are the same, it means the student completed the term but did not re-enroll in (or was not retained by) that institution.
An “N/A” status can be returned at the discretion of the institution where the student was enrolled.
An institution can elect to release or withhold the enrollment record and enrollment status.
