Bernir bod gwasanaethau addysg awdurdod Sir Fynwy yn anfoddhaol oherwydd bod eu perfformiad o’u cymharu ag ysgolion tebyg, ar sail yr hawl i brydau ysgol am ddim, gryn dipyn yn is na’r cyfartaledd ac mae’r cynnydd rhwng yr ysgolion cynradd a’r ysgolion uwchradd hefyd gryn dipyn yn is na’r cyfartaledd. Mae cyfanswm nifer y dyddiau a gaiff eu colli yn sgil gwaharddiadau am gyfnodau penodol hefyd yn rhy uchel. Daeth y tîm arolygu i’r casgliad nad yw trefniadau’r awdurdod ar gyfer cefnogi ysgolion a’u herio yn ddigon cadarn ac nid ydynt wedi sicrhau digon o effaith. Mae eu gwaith cynllunio strategol ar gyfer anghenion dysgu ychwanegol yn wan. Mae’r ffaith nad yw trefniadau’r awdurdod ar gyfer diogelu yn bodloni’r gofynion hefyd yn gryn destun pryder.
In Monmouthshire the authority’s education services are found to be unsatisfactory because performance when compared to similar schools, according to free-school-meal entitlement, has been well below average. The progress between primary and secondary schools is also well below average.  The overall number of days lost to fixed term exclusions is too high. The inspection team found that the authority’s arrangements for supporting and challenging schools are not robust enough and have not had enough impact.  Their strategic planning for additional learning needs is weak.  It is also of considerable concern to note that the authority’s arrangements for safeguarding do not meet requirements.
