The school has 850 students, 300 of whom are boarders, and is led by members of the Jesuit order (Society of Jesus).

In addition there is a varied program of extra-curricular activities ranging from rugby to drama.

After World War II, the Jesuit order re-opened the school in 1946, which in war-torn Germany was only possible in light of significant material aid from Pope Pius XII.

In 2010, Padre Wolfgang S. admitted to several acts of sexual abuse of minors during his years as a teacher in Sankt Blasius from 1982 to 1984.

Stefan Dartmann stated that Wolfgang had also committed acts of sex abuse in Spain and Chile.
