Hoërskool Wonderboom also known as Wonnies, is an Afrikaans-medium public high school situated in the city of Pretoria, Gauteng, South Africa, on the southern slopes of the Magaliesberg.Early historyIn 1925 a commission headed by J. A. Friis, started an action to establish a high school in the Moot. The former Department of Education was not inclined to an Afrikaans high school building.In 1928 the then MEC for Education, Mr. Michael Brink, made a promise for a new Afrikaans high school. Up until 1943 the matter was still on ice. A new Afrikaans high school was not on the agenda of the Department of Education. Mr. Michael Brink again decided to undertake the matter further.On June 14, 1944, a site was recommended and approved on February 13, 1946. This area was the now famous, southern slope of the Magaliesberg east of Voortrekker Road. In November 1946 the first sod was dug by mr. Michael Brink.Mr. J Dey was the architect, Mr.. J D Verhoewe the contractor and mr. C. Morgan, chairman of the action committee.Eventually, after many years, the first Afrikaans High School was established in the Moot, under the name Michael Brink Hoër. A year later, on June 10, 1950 the Administrator of the Transvaal announced that: the school will from now on be known as Die Hoërskool Wonderboom. It was the first step in the direction of the rich traditions, beautiful grounds and outstanding features of Hoërskool Wonderboom, as it is known today."Grow and Serve" is the motto of the school upheld throughout the past 58 years. This motto and badge was introduced at the end of 1950. The school song was the next milestone. Mr. J. A. van der Walt, a teacher was the author of the lyrics and the famous Stephan Eyssen wrote the music. The school song was officially inaugurated at the matric farewell in 1953.
"‘n Skool van uitnemendheid waar elke individu geleenthede het om ten volle te ontwikkel sedert 1949.In Januarie 1949 het 272 leerlinge en 28 personeellede vir die eerste keer die terrein betree van 'n nuwe hoërskool teen die hange van die Magaliesberg. Die amptelike naam "Die Hoërskool Wonderboom" is aangekondig op 10 Junie 1950. Dit verwys na die Wonderboom anderkant die berg, wat volgens oorlewering onsterflik is. Hierdie boom is op die wapen verewig en die leuse "Groei en dien" word nog steeds met mag en mening, en tipiese tieneruitbundigheid, uitgeleef.Die gemoedelike noemnaam "Wonnieland" het mettertyd staanplek gekry in die harte van almal wat hierdie pragtige geboue, vol karakter en tradisie, se trappe geklim het."
