When the city of Fredericton was initially laid out in 1758, city planners set aside a plot of land in the downtown region that was intended to become a school. That school was incorporated in 1790 as the College of New Brunswick and was intended to be a boarding school, patterned after the boys' public schools in England. In 1829 when King's College opened in Fredericton, the school was renamed to the Collegiate Grammar School, and was supported by the college. In 1871, the Free School Act was enacted, and the school again changed its name, this time to the Collegiate High School. At this time it became a preparatory school for King's College, which by then had become the University of New Brunswick.

FHS copes with the Syrian exodus edit

In July 2016, Fredericton High School attracted media attention after The Rebel^[4] obtained internal documents discussing the transitional challenges of hosting new students fleeing the Syrian Civil War.^[5] Said administrator Chantal Lafargue,^[5]

We are living in a province where there are no official EAL (English as an alternative language) courses for high school, no alternate programming for war-affected youth, no personnel that have designated roles, like translator-interpreters, for example to help us settle youth down, make them feel at ease and help them navigate a whole new set of cultural and social norms.

Canadian Minister of Immigration John McCallum has said that while the refugee program is a federal responsibility, schools are a responsibility of the provinces.^[5]
