The school's indirect predecessor is Precious Blood Golden Jubilee Secondary School, which was administered by the Sisters of the Precious Blood. In 1977, due to misusage of school funds and suspected corruption, some teachers contacted the ICAC and informed the students. It was followed by the diocese's take-over and suppression, a series of student protests and sit-ins, and eventually the closure of the school on 14 May 1978. St. Teresa Secondary School was opened on its former site, with the protestors initiated the secular Ng Yuk Secondary School.
