Bydd y cynllun treialu yn canolbwyntio ar gefnogi disgyblion difreintiedig ac ysgolion yr effeithiwyd arnynt yn sylweddol yn ystod y pandemig. Mae'r cynlluniau wedi'u llywio gan fodelau rhyngwladol a chynigion a wnaed gan y Sefydliad Polisi Addysg. Cynhelir y gwaith ar y cyd â Grŵp Senedd Plaid Cymru fel rhan o'r Cytundeb Cydweithredu rhwng Llywodraeth Cymru a Phlaid Cymru.
The school day trials will be focused on supporting disadvantaged pupils and schools particularly affected during the pandemic. The plans draw on international models and proposals made by the Education Policy Institute. This work will be carried out in collaboration with the Plaid Cymru Senedd Group, as part of the Co-operation Agreement between the Welsh Government and Plaid Cymru.
