The school was finished in October 1967, to replace Southampton Regional High School, the site of which was flooded by the construction of the Mactaquac Dam. Some classes were housed in temporary portable classrooms until 1971, when the Nackawic Junior High School was finished.[4]
Originally, the school housed grades 7-12. Later, grades 7-9 were moved to the Junior High. In the 1990s, an addition was built on to accommodate grade 9, which was transferred back from Nackawic Middle School.
The French education program, originally a separate school (École Heritage de Nackawic), was established in October 1984 and housed in a group of portable classrooms[4] to the side of the main building. The program was later shifted to the main building. The portables were later retired because of vandalism.
Sports
The Nackawic High School Boys' Soccer Team won its first provincial championship in the fall of 2014. They defeated Stanley High School 2-1 on penalty kicks. Winning the provincial championship capped off a perfect season- regular season champions and regional champs. They had an impeccable record despite only losing one game- 1-0 to Carleton North in exhibition play. This year, the Nackawic High Schools Girls' Soccer Team made history by qualifying for the first time in 10 years for Regionals where they defeated McAdam To qualify for provincials for the first time ever in history. Also they beat Hartland in overtime to get the first-place position at provincials. Unfortunately, they were defeated by Peticodiac 1-0 at provincials and didn't advance to finals, but they had a great season
