I had a call and she is wondering if there is a release form for co-supervisors to allow them to discuss the candidate.

NSRP does not see it as problematic for the co-supervisors to speak about the candidate, Both supervisors have been jointly approved and all parties were sent the letter of approval, In fact, NSRP sees this communication as very appropriate and supports such coordination. However, NSRP has not established a specific consent form for this purpose. If you would feel more comfortable setting up express consent, you could discuss this process with the candidate and even document this agreement with the candidate, if you would like to do so.
