As used in this chapter, unless a different meaning is plainly required by the context:
"Employee" does not include supreme and circuit court judges, any person whose services are remunerated solely by per diem payments, or any person employed by a school, college, or university at which the person is enrolled as a student or otherwise regularly attending classes for academic credit unless the person is employed as a school bus driver and is paid by the same school district in which the person is enrolled in school. In determining student status, the system may consider the guidelines of the Social Security Administration regarding student services and other criteria the system uniformly prescribes.
