Yn dilyn arolygiad Estyn o wasanaethau addysg Cyngor Bwrdeistref Sirol Torfaen ym mis Hydref 2011, cafodd yr awdurdod ei enwi fel un a oedd angen Gwelliannau Sylweddol a nododd Estyn bum argymhelliad y dylai'r awdurdod weithredu arnynt. Yn ystod yr ymweliad monitro dilynol, daeth Estyn i'r casgliad bod yr awdurdod wedi mynd i'r afael yn rhannol â 3 o'r argymhellion hynny ond heb fynd i'r afael â'r ddau arall. O ganlyniad, ym marn y tîm arolygu, annigonol oedd y cynnydd a wnaed gan yr awdurdod o ran mynd i'r afael ag argymhellion yr adroddiad arolygu, araf fu'r gwelliannau a dylid gosod yr awdurdod yn y categori Mesurau Arbennig.
Following Estyn’s inspection of Torfaen CBC’s education services in October 2011 the authority was identified as requiring Significant Improvement and Estyn identified five recommendations for the authority to address. During the subsequent monitoring visit, Estyn concluded that the authority had partially addressed 3 of these recommendations and not addressed the remaining two. As such, it was the view of the inspection team that the authority had made insufficient progress to address the recommendations in the inspection report, improvements had been slow and the authority should be placed in the category of Special Measures.
