Hoërskool Voortrekker is a public Afrikaans medium co-educational high school situated in the municipality of Boksburg in the city of Ekurhuleni in the Gauteng province of South Africa.

Louw and the remnants of the Boksburg Commando laid down their weapons finally at Kraal station, just south of Heidelberg.

The scoured earth policy of the British government had the consequence that there was an influx of Afrikaners looking for work on the coal and gold mines on the Witswatersrand.

After the war Ds Louw started campaigning for the establishment of a secondary school for Afrikaans speaking children on the Witswatersrand.

As one of the last surviving preachers who had stayed with the Boer forces throughout the war, he was asked to deliver the sermon at the foundation stone laying for the Voortrekker Monument on 16 June 1938 Voortrekker High School[4][5] was the first Afrikaans school on the Witswatersrand.

Through the hard work of Louw, the OOSRANDSE HOLLANDSE MEDIUM HOËRSKOOL was established on 29 January 1920.

In 1923 du Toit became the new principal and shortly afterwards the erection of a permanent school building began.

On 30 July 1924 the new school buildings were officially inaugurated by Professor J. H. Hofmeyer, Administrator of Transvaal.

Anton van Wouw, the sculptor, was commissioned to create a bas-relief depicting the "Groot Trek".

In the same year the new colours (blue, green and yellow) were accepted and the motto "Voorwaart" was changed to "Vorentoe".
