St. Germaine School is operated under the auspices of the Catholic Bishop of Chicago, a corporation sole, in the Archdioceses of Chicago. St. Germaine admits students of any race, color, sex, national and ethnic origin to all the rights, privileges, programs and activities generally made available to the students in the school.

St. Germaine School will admit non-Catholic students provided these students will not displace Catholic students and that both students and parents clearly understand that participation in Catholic religious instruction and school activities related to the Catholic character of the school is required.
