創校與機遇 (1977-1993)
七十年代中期，本港推行九年免費教育，中學學位需求殷切，香港天主教教區與教育署商議後，同意接收南昌街石硤尾官立小學校舍，開辦一所男女文法中學。
1977年九月，聖芳濟各書院正式開校，儲富有先生擔任校長，設有中一級四班。由於改建工程尚未完成，開校首月借用白田天主教小學的課室上課，十月改建工程完畢，學校正式遷入，與石硤尾官立小學共用校舍；直至1980年，我校完全接管校舍，是年增至十二班。
開校伊始，學校漸次成長，成績斐然，學生在學業成績、體藝活動、公民教育活動均獲得卓越成就。及至1990年，由於校舍空間不敷應用，校董會建議申請遷校至粉嶺，在教區大力支持下，遷校工作正式展開。
School founded and the opportunities seized (1977-1993)
In the mid-1970s, 9-year free education was implemented in Hong Kong. As a result, there was a high demand for secondary school places. Discussion between The Catholic Diocese of Hong Kong and the Education Department ensued and it was agreed that the Catholic Diocese of Hong Kong would utilise the grounds of Shek Kip Mei Government Primary School on Nam Cheong Street and set up a co-educational grammar secondary school.
In September 1977, with Mr. Chu Fu Yau as the Principal, St. Francis of Assisi’s College was officially set up. There were four form one classes. As renovation work had not yet been completed, the school operated on the campus of Pak Tin Catholic Primary School. One month later, the school moved in and shared the premises with Shek Kip Mei Primary School. It was not until 1980 that the school took over the entire campus and the number of classes increased to twelve.
As the school gradually developed, the students achieved excellent academic results as well as achievements in sports, art and civil education. In 1990, due to the lack of campus space, the School Management Committee proposed to relocate the school to Fanling. With full support from the Catholic Diocese of Hong Kong, relocation work officially started.
