Gwyddom fod gennym rywfaint o waith i’w wneud gydag ysgolion a cholegau er mwyn sefydlu’r dull newydd, nid yn unig er mwyn sicrhau bod y data yr ydym yn ei ddefnyddio’n gywir. Byddwn yn cyflwyno’r mesurau newydd cam wrth gam gan fod y gwaith o’u datblygu ar wahanol gamau. Fodd bynnag, bydd y tri mesur ar waith yn unol â’r amserlen, a hynny erbyn dechrau 2019.
We know we have some work to do with schools and colleges to establish the new approach, and not least to make sure that the data we are using is accurate.  There will be a staged approach to the introduction of the new measures as they are at different stages of development. However, all three measures are on schedule to be in place by early 2019.
