In 1993, Elda Mahlentle started a school in the informal settlement called Chuku Town, opposite the racehorse stables in Milnerton. Grades 1 to 4 were housed all in one small shack. By the end of 1994 the school had expanded up to Grade 9 and consisted of eight container classrooms. The Department of Education subsidised the school through payment of ten teachers' salaries. In 1996 the new houses were being built in Joe Slovo and so the school moved there with 16 educators. After lengthy negotiations the school finally became a public school in 2004. Elda Mahlentle Primary School became Sinenjongo High School and Marconi Beam Primary School.

In 2012, the 11A grade class at the school lobbied South African cellphone network operators to provide free access to Wikipedia to assist students with research. FNB Connect was the first to respond by offering free Wikipedia browsing during certain hours to their own clients. While this offer is not available to cellphone users, it will put more pressure on the cellphone network operators to offer the same. In May 2013, the school was visited by Victor Grigas and Charlene Music from the Wikimedia Foundation to shoot a documentary about the school and this campaign. Plus, in June 2013, national, provincial and local newspapers, published the students' letter and had articles written about it, especially on the week preceding the South African national holiday of 16 June "Youth Day". The letter has received a voice beyond its home-province, the Western Cape, to provinces like the Gauteng and the KwaZulu Natal and continues to strengthen it through the Free Access to Wikipedia from Cellphones Facebook page. On 14 February 2014, in response to a NekNomination challenge from Five Roses Tea, the cellphone operator MTN Group announced via a YouTube video that they would provide access to Wikipedia without data charges. A NekNomination is an internet craze that started as a drinking game, but developed into an online challenge to make a positive difference in South Africa. The Gr 12A learners have written a number of articles for the IsiXhosa Wikipedia. :xh:Ukucinezeleka kwamanina|'Ukucinezeleka kwamanina' by Sinako Mtakati took first prize in a competition held in August 2013. In 2014 grade 11A learners joined WikiAfrica and started editing and creating articles.

Yearly events
There is a Careers day for the Grade 8s and Grade 9s where people from different career fields speak to the learners and let them know about those career fields. This is done because the learners in Grade 10 have to choose subjects that they'll major in until matriculation. The other grades' pupils get included too. Annually there is an academic awards ceremony for the Grade 12 class. It is also their valedictory. A month before the valedictory, the school has a social farewell celebration for the Grade 12 class known as the "Matric Dance" or "Matric Ball"
