St Monicas Diocesan School Primary School is located in Matatiele. St. Monica's Diocesan School is an English medium, non-racial, co-educational school, providing a solid foundation (spiritually, emotionally, physically, intellectually and socially) that prepares the child for life in a multi-cultural world and develops the child to his/her full potential in order to face the future with confidence.

St Monica's has grown out of St Stephen's Playschool, which first opened it doors in 1990 in response to the community's expressed needs. During 1993 it became clear that the demand for English medium education in Matatiele was such that the existing schools could not cope on their own. The St Stephen's Playschool community then approached the Church authorities with the request to facilitate the opening of a school.

The Church agreed and offered the disused church of St Monica's in Seymour Street, as a site. A Board of Governors made up of representatives of the local church and parents was constituted. After much hard work the school opened with 24 children in two classes on the 18th January 1994.
