If the Rex Mundi students chose to continue in the Catholic high school system, their options were either be transferred to Mater Dei or Reitz Memorial. Juniors were allowed to decide which school they wanted to attend, however, underclassmen had to go to the school in their district. They began visiting Mater Dei and Reitz Memorial high schools to become acquainted with future classmates and teachers. Each day, fifteen Rex Mundi students from the freshmen, sophomore, and junior classes spent their school day at one of the two schools. A Rex Mundi student was assigned a student at the host school with similar academic interests to provide a tour. This allowed the Rex Mundi student to get an idea of what the classes at his or her new school would be like. The school board was “firmly committed” to providing adequate transportation.
