The teaching of Welsh history is to be made mandatory in schools in Cymru.
The Co-operation Agreement says that both parties will "improve the teaching of Welsh history, taking account of the Estyn report".
The parties have "committed to Welsh history being mandatory in the new Curriculum for Wales" adding that "new curriculum resources will be developed to support Welsh history in all its complexity and diversity".
The Co-operation Agreement
In response to the Agreement, First Minister Mark Drakeford said “This Co-operation Agreement brings the Welsh Government and Plaid Cymru together to respond to some of the most pressing issues facing Wales today, such as climate change and the energy and cost-of-living crisis."
“We can achieve more for people in Wales by working together and the Co-operation Agreement is both a response to the external challenges we face and a chance to build on the opportunities in our future. It will also help us secure a stable Senedd over the next three years, capable of delivering radical change and reform.
“These commitments build on our shared values of social solidarity, a sustainable planet and a vibrant democracy.”
