Yn eu dyfarniadau cyffredinol canfu timau arolygu Estyn fod perfformiad presennol gwasanaethau addysg y ddau awdurdod lleol yn anfoddhaol. Canfu hefyd fod rhagolygon yr awdurdodau lleol ar gyfer gwella yn anfoddhaol. O ystyried y diffygion difrifol hyn cred Estyn fod angen cyflwyno mesurau arbennig o fewn y ddau awdurdod lleol hyn.
In their overall judgements the Estyn inspection teams found that the current performance of both of the local authorities’ education services are unsatisfactory and also found that both of the local authority’s prospects for improvement are unsatisfactory.  In light of these very serious shortcomings, Estyn believe that special measures are required in relation to both of these authorities.
