On 1 August 1950, the Dominican Sisters opened the first Catholic School in Rustenburg. St Margaret’s Convent, as it was then named, was situated on the corner of Smit and von Willeigh Streets in Rustenburg Town and had a grand total of 15 students. The school was registered by the Transvaal Education Department on 15 November 1950.

In 1961, the Dominican Sisters withdrew from Rustenburg, to be replaced by the Sisters of Charity of St Paul the Apostle who continued to grow the school in number and in excellence.

By 1966 the number of enrolments at the school necessitated the move to a more spacious area and the present day Selly Park Convent School was born. Selly Park Convent is named after the Mother House of the Sisters of St Paul in Birmingham, England.

Selly Park Convent continued as a Primary and High School until December 1982 after which time the High School and boarding facilities were phased out. Selly Park Convent Primary School then became what it is today, an English medium , primary, day school catering for students from Grade RR to Grade 7.
