Tshilidzini Special School has only one therapist while 11 posts for therapists are vacant.
Helene Franz School does not have a therapist and there are two vacancies.
Motshekga revealed both schools were receiving therapeutic support from staff appointed through a grant for pupils with severe to profound intellectual disabilities.
She said 36 posts for special schools for pupils with severe to profound intellectual disabilities have been advertised for filling from April next year.
Victor Mavhidula, provincial manager for the SAHRC in Limpopo, said had they been aware of the situation, they would have attended to it long ago.
“We prioritise special schools because we know the moment you don’t give support it means you are denying those pupils their right to access education. We will visit the two schools in early January to find out what is happening.
“We need to hold the department accountable for this because it’s not a new issue.”
