Yn ystod gwaith y Bwrdd Cynghori, daeth yn eglur bod angen edrych o'r newydd ar y ffordd y caiff ysgolion eu categoreiddio yn ôl eu natur ieithyddol a darpariaeth iaith gan nad oedd hyn wedi’i ystyried ers dros 10 mlynedd.  Cytunwyd y dylid gwneud hyn yng nghyd-destun y cwricwlwm newydd.
During the Advisory Board’s work it became clear that there was a need to take a fresh look at the way schools are categorised according to their linguistic nature and language provision as it has not been looked at for over 10 years. It was agreed that this should be done in the context of the new curriculum.
