A school policy may require a student to provide an SSN to enroll in school. Some
schools use the SSN as a student identifier, when the student has one. However, because
schools are not mandated to use the SSN in administering educational programs, when
students do not have an SSN or prefer not to provide their SSN, the school should
assign the student an internal student number.
Although the application forms for the SAT, GRE, and other educational tests have
a space to show the SSN, the student is not required to provide an SSN to take the
test. SSA does not assign an SSN solely for this purpose.
