The origin of BAM was the "Nuestra Señora de Begoña" School of Teaching, which was founded in 1948. In 1978, it was transformed into a University School by the University of Bilbao (now UPV / EHU).
BAM continues to maintain the values on the basis of which it was founded that define it for being Christian and for its willingness to promote from the cultural values of the Basque Country the formation of professors who promote the scientific, social and political pluralism characteristic of any society Truly democratic.
