While Catholic high schools position their students for academic success, the emphasis is on work ethic, service, critical thinking, leadership skills and a solid moral foundation.
Ninety-eight percent of Catholic high school students graduate from high school and ninety-five percent attend college after graduation.

Paul McCaughey, OP, Superintendent of the Catholic Schools of the Archdiocese of Chicago. “Test scores do not say everything, but they do speak to strong parental, teacher, and student expectations.”
