History 

Zamboanga del Norte National High School’s takeoff can be traced to 1946. "We don't choose the best, we make them." The populace’s desire for higher education caused them to travel to nearby island provinces of Negros and Cebu. The provincial government of Zamboanga Peninsula, through former Governor of Zamboanga Province Felipe B. Azcuna, arranged the transfer of Zamboanga Provincial High School, then operating in the erstwhile capital town of Zamboanga (now Zamboanga City), to his hometown in Dipolog. A drawback is the school's dearth of physical facilities. Since its first hosting of the 1964 Mindanao Athletic Meet, the school has been the venue of a series of local, regional, and national sports fests. In 1982, the Palarong Pambansa caused a renovation of the Zamboanga del Norte Sports Complex where the school is. This renovation required the demolition of 46 classrooms and the Administration Building. While the ZN Sports Complex may be the best in the region, the replacement of the lost classrooms at the back of the three grandstands remains a faint promise. Since the opening, the Zamboanga del Norte National High School is under the jurisdiction of the Division of Zamboanga del Norte; then was transferred to the Division of Dipolog per Republic Act 8174, otherwise known as the General Appropriations Act of 1996 for all budgetary transactions. Due to the influx of students from neighboring towns and the City of Dapitan, the school needed more space and more rooms. Through the efforts of Patricia G. Ratilla, one of the faculty members, ownership of a lot in Turno, which is a property of the national government for the establishment of the City Normal College, was transferred to ZNNHS through a bill authored by the former Congressman Ernesto S. Amatong. Hence, the existence of the ZNNHS (Campus II) Turno Campus today. Academics
