Pius XI High School is a private Catholic high school located in Milwaukee, Wisconsin. It is in the Roman Catholic Archdiocese of Milwaukee. Its enrollment is approximately 900.
 
History
Pius XI High School, named in honor of Pope Pius XI, was founded in 1929. Originally it offered only the first three years of high school.[3] Thus, the first graduation occurred in 1937, when the first senior class was added to the school. Enrollment grew from a class of eight in 1937 to over 2,000 students throughout the 1960s and 1970s. Current enrollment is approximately 900 students.
The original four-story school building was constructed in 1930, with a two-story addition, for six stories total, completed in 1957. Additional classroom space, library space, science laboratories and general renovations were completed in 1998, and a field house was annexed in 2004. The original gymnasium has been remodeled into an auditorium, which was completed in the 2012-2013 school year.
 
Schedules
Instead of homerooms, Pius has TAC (Teacher Advisor Contact) rooms, a mixture of freshmen, sophomores, juniors and seniors. Each TAC is headed by a staff member called a "TAC teacher" that offers guidance to its TAC students. Pius has a modular scheduling system consisting of sixteen "Mods" of 22 minutes each, with 4 minutes between mods. Most classes are 2 mods long, making them a total of 48 minutes long (2 mods of 22 minutes, plus 4 minutes in between that are spent in class.). Courses meet two, three or four times per week and last from 22 minutes to 90 minutes. This system provides flexibility in the frequency and duration of individual courses, and approximates the scheduling systems used by colleges and universities.
