Rwy’n dal i fod yn gwbl argyhoeddedig nad oes lle i gynghreiriau wrth wella ysgolion yng Nghymru. Gallant beri cynnen yn ogystal â bod yn gamarweiniol ac nid ydynt, ohonynt eu hunain, yn ysgogi gwelliant. Os mai cynghreiriau yw’r allwedd i ysgolion rhagorol, yna Lloegr fyddai ar frig sgoriau PISA. Ond nid dyna’r sefyllfa – o bell ffordd.
I remain absolutely committed to the belief that there is no role for league tables in the improvement agenda for Wales.  They can be divisive and misleading and do not in themselves promote improvement.  If league tables were the key to high performing schools then England would be at the top of the PISA scores.  But it is not – by some distance.
