Adolf Hitler Schools (AHS) were 12 elite boarding schools run by the SS in Nazi Germany from 1937 to 1945. Their aim was to indoctrinate young people into the ideologies of the Nazi Party. They were for young people aged 14 to 18 years old and were single sex, with three schools for girls and the rest for boys. Selection for admission to the schools was rigorous; pupils were chosen for their political dedication and physical fitness, as opposed to their academic prowess. Activities focused on political indoctrination rather than academic studies. The SS often selected future officers from the schools.
