Do not grant others access to student information by allowing them to use your NetID. Your NetID and password are your electronic identification. The University’s Information Security Policy explicitly forbids sharing it: User access information is not to be shared. Users are responsible for maintaining the security of their IDs and all activity occurring under those IDs.
Even if you believe someone has a legitimate reason to access student data, that person must be authorized through appropriate University channels. You are responsible for any misuse of data that takes place through use of your ID. Always protect your electronic identity.
