FERPA permits disclosure of education record information without the student's consent to school officials who have a legitimate educational interest in the information. A school official has a legitimate educational interest if the official needs to review an education record in order to fulfill their professional responsibility.
The demonstrated "need to know" by those officials of an institution who act in the students' educational interest, including faculty, administration, clerical and professional employees, and other persons who manage student record information including student employees and agents.
Ask yourself: "Do you need that information to do your job? Would your colleagues agree?"
Faculty members are considered school officials as defined by FERPA. Faculty members are given access to class and grade rosters as well as to current advisee information. Beyond this, faculty members must demonstrate a legitimate educational interest in order to receive additional student-record access. Any person with access to student records, regardless of title or status, should consider educational need to know before accessing a record. Just because you CAN, doesn't mean you SHOULD.
