James Evans is pressing the Welsh Government to boost training for teaching assistants.
The Brecon and Radnorshire MS asked at the Senedd what the Welsh Government is doing to support teaching assistants in schools.
He said they are vital to delivering the new curriculum for Wales.
But many say they don't get enough training on delivery of the curriculum or upskilling themselves to be able to help teachers in the classroom.
Mr Evans asked Education Minister, Jeremy Miles: “What is the Government doing to upskill teaching assistants and to educate them on the new curriculum and how they can best deliver that to pupils?”
Mr Miles said the Government is committed to enabling teaching assistants to improve their skills and to help them engage with professional learning.
He told Mr Evans: “We are working closely with our partners to facilitate clearer learning pathways, including pathways to achieve the status of higher level teaching assistant.”
