Cyhoeddais mewn Datganiad Ysgrifenedig ar 25 Medi 2014 fod System Genedlaethol ar gyfer Categoreiddio Ysgolion yn cael ei chyflwyno ar gyfer ysgolion cynradd ac uwchradd. Cyhoeddais hefyd yr ystod o fesurau a fydd yn cael eu defnyddio i asesu ysgolion cynradd ac addewais roi diweddariad pellach maes o law ar y mesurau ar gyfer ysgolion uwchradd.
I announced in a Written Statement on 25 September 2014 the introduction of a new National School Categorisation System for both primary and secondary schools.  I also announced the range of measures to be used to assess primary schools and promised to provide a further update in relation to secondary school measures.
