Neithiwr (nos Sul) am 18.57, anfonodd Llywodraeth y DU beth o’r dystiolaeth yr ydym wedi bod yn gofyn amdani. Mae’n anffodus dros ben bod y dystiolaeth sydd, i bob golwg, wedi bod yn datblygu dros yr haf wedi’i dal yn ôl nes y noson cyn diwrnod cyntaf y tymor newydd. Mae hefyd yn anghyflawn, sy’n golygu nad oes gennym y darlun llawn y tu ôl i newid polisi sydyn Adran Addysg San Steffan o ran rheoli RAAC mewn ysgolion. Rydym yn parhau i ofyn am adroddiadau strwythurol manwl peirianwyr yn amlinellu’n glir amserlen a dadansoddiad technegol o’r digwyddiadau a arweiniodd at gyhoeddiad dydd Iau diwethaf bod ysgolion yn cau. Gall swyddogion ystyried hyn wedyn a’i rannu ag awdurdodau lleol, sydd â chyfrifoldeb statudol dros adeiladau ysgolion yng Nghymru.
Last night (Sunday) at 18.57, the UK Government sent some of the evidence that we have repeatedly requested. It is hugely regrettable that the evidence that has apparently been developed over the summer has been withheld until the night before the first day back of term.  It is also incomplete, leaving us without the full rationale for the DfE’s sudden policy change towards the management of RAAC in schools.  We continue to request detailed structural engineer reports that clearly set out the timeline and technical analysis of events leading up to last Thursday’s announcement of school closures. This can then be reviewed by officials and shared with local authorities who have statutory responsibility for school buildings in Wales.
