This flag indicates the results obtained from a match with the National Student Loan Data System (NSLDS). This flag, combined with the NSLDS Match Flag, gives you the status of a student’s loan and Title IV overpayments (Pell, FSEOG, TEACH, Iraq/Afghanistan Service Grant, and Perkins).

The ISIR codes and their meanings are as follows:

1 Match found, NSLDS data sent.
2 Incomplete match, no data sent.
3 No match found. No record in NSLDS for that ID.
4 Match found but no data sent to CPS. Student’s ID is in the database, but no other information is available.
5 Real-time transaction not sent to NSLDS.
