The Family Educational Rights and Privacy Act (FERPA) guarantees students access to their educational records and prohibits dissemination of educational records without the student’s consent.
All student data maintained by UIUC is part of the educational record, including but not limited to: all biographical, all application and all matriculation data. Other than public information classified as "directory information," there is to be no release of the educational record to any party without the express written consent of the student. If your son or daughter has chosen to suppress his/her directory information, there is less information to share. Instead, all staff is instructed to say, "There is no information available for any student by that name." The University must comply with these federal regulations or be subject to penalties which could include loss of federal funding. It is possible for your student to sign a written consent form that allows access to their record.
The best advice is to talk to your student. Remain involved and ask questions about their classes, their schedule, and their degree requirements. The student's college dean is available to assist with general questions pertaining to undergraduate academics, and you should not hesitate to contact the Office of the Dean of Students if you have an emergency or other threatening concern about your student!
