Rwy'n llwyr dderbyn argymhellion yr OECD a byddaf felly, o hyn ymlaen,  yn cael gwared â'r arfer o osod ysgolion mewn grŵp safonau ar sail data fel rhan o Gam 1 y System Genedlaethol ar gyfer Categoreiddio Ysgolion.
I fully accept the OECD recommendation and will therefore be removing the data-driven judgement that places schools into a standards group as part of Step 1 of the National Schools Categorisation System from this point on.
