The school was established on February 11, 1920 under the name REPTC, with 14 pupils (13 girls and a boy).
At the beginning of 1922 the scholars moved into Nobby’s Bar and the Voortrekker School took over the arcade. This took place at the time of the 1922 strikes and the Rand Revolt, a very volatile time on the East Rand and particularly in Boksburg.
Over time, Grade Eight was added to those already at the school, which also necessitated additional teachers.
In 1924 the hope of having a new building grew as the school was doing so well. In those days funds were raised from the making of tennis courts, a cadet corps, a shooting range, a radio society and the division of the pupils into houses.
In that same year the first Boksburg High School magazine was produced in November 1924.
The name of the REPTC was a problem, because it was associated with a teacher training facility whereas it was a high school.
In 1925 the school officially changed its name to Boksburg High School.
Sports fields were finally finished in 1926.
In early 1930, Boksburg High School managed to move into the new structures at the present site.
The first part of the school is the area around the Acheson Quadrangle, before the media centre was the school hall and the floors and windows of the classrooms had to be replaced in 1979.
In the interim, more specialist rooms had to be constructed.
In the early 1980s there was a great deal of building activity when the premises adjacent on the eastern side, which was Baanbreker Laerskool, were taken over. A pool was also completed on 1960.
In 1980 the old gravel hockey field was grassed and the media centre was renovated.
Today all classrooms have been wired and have access to the internet, through laptops, and all have fixed projectors.
