In compliance with FERPA, you cannot:

Use even a portion of a student's social security number (SSN) or G00# in a public posting of grades (You CAN post grades if they are not in alphabetical order and if you use a unique identifier known only to the student and you). For example: a student gives a generic number (542876) that is not a part of the student SSN or G00 number.
Link the name of a student with that student's SSN or G00# in any public manner.
Leave graded tests in a stack for students to pick up by sorting through the papers of all students.
Circulate a printed class list with student names, SSN's, G00#'s, or grades as an attendance roster.
Discuss the progress of a student with anyone other than the student (including parents) without the written consent of the student.
Provide lists of students enrolled in your classes for any commercial purpose.
Provide student schedules or assist anyone other than SCF employees in locating a student on campus.
