In a statement seen by TimesLIVE, commissioner Tembinkosi Bonakele said school uniforms contribute to social cohesion, inclusion and school identity. He said overpricing them can cause exclusion.
Bonakele said the investigations have been ongoing for more than a decade.
Working with the basic education department, the commission was able to guide schools and other stakeholders about the procurement of school uniforms.
Bonakele said among complaints from parents was that schools had recommended exclusive uniform suppliers which overpriced uniforms and made them unaffordable.
“We found the exclusive arrangements between schools and uniform suppliers were pervasive across the country and made uniforms unnecessarily expensive and increasingly unaffordable for many South Africans.
“The commission also found several schools were overly prescriptive in their uniform choices. This limited the choices and bargaining power of parents who were beholden to a small number of suppliers.”
Bonakele said the agreement entered into involves four school groups and two of the largest manufactures and suppliers of school uniforms.
