Zamboanga City High School(main) has a total population of 9,876 today - a far cry from its humble beginning way back 1945 which marked the formal opening of the school with classes held under tents donated by the United States Army. As a response to its first principal's suggestion, another school was created in a new site at the old Lantaka flats where its first classes were held, and this was c
alled East City High School while the original one located in Baliwasan, was named West City High School. In 1956-57, the two schools were merged into one high school. It was then moved to Pettit Barracks, the present site of Zamboanga City High School (Main). Along with its progress, were professionals it has produced, some of who are the high-ranking officials of Zamboanga City today. Known lawyers, engineers, nurses and many others sentimentally looked back at Zamboanga City High School where their potentials were harnessed and developed. At present, Mrs. Eloisa B. Ruste, is the sixth principal and is on her eleventh year at the helm of ZCHS Main.
