Yn dilyn arolwg o’r gwasanaethau addysg ar Ynys Môn ym mis Mai 2012, cyhoeddodd Estyn ei adroddiad ar yr arolwg ddiwedd mis Gorffennaf.  Barn  gyffredinol Estyn oedd bod perfformiad presennol gwasanaethau addysg yr awdurdod lleol yn anfoddhaol, a hefyd bod rhagolygon yr awdurdod lleol ar gyfer gwella yn anfoddhaol.  Yng ngoleuni’r diffygion difrifol iawn hyn, mae Estyn yn credu bod angen mesurau arbennig ar gyfer yr awdurdod hwn.
Following inspection of the education services in Anglesey in May 2012, Estyn published its inspection report at the end of July.   In its overall judgements the inspection team found that the current performance of the local authority’s education service is unsatisfactory and also found the local authority’s prospects for improvement unsatisfactory.  In light of these very serious shortcomings, Estyn believe that special measures are required in relation to this authority.
