The Perpetual Help Anglo Chinese School was founded in September 1955 by two Spanish Redemptorist Fathers - Juan Campos Rodríguez and Eusebio Arnáiz Álvarez at Estrada da Vitoria, 28.

The Kindergarten and Primary School started with few pupils only. Two years later, registrations increased and six more classes were built; other classes were added in 1962. In 1964 another new building was constructed. This was blessed by Cardinal Don Jose da Costa Nunes, with the assistance of several bishops including Mgr. Caprio Apostolic Internuntius of Taiwan, on 9 December 1964.

In September 1964, the Secondary School was introduced for boys and the following year it was opened to girls too. In 1966, the school bought an adjacent house, but the Redemptorist Fathers left Macau in June 1967.

The school was taken in 1967 by the Society of Divine Love: a feminine institute founded in Macau by Fr. Eugenio Isamar (S.J.). The school's name was "Perpetual Help College".
