Cynhaliodd Ofqual eu hymchwiliad eu hunain i ddyfarniadau Saesneg TGAU yn 2012 yn Lloegr a chyhoeddwyd ei gasgliadau cychwynnol ddydd Gwener 31 Awst. Dyma a ddywedodd Ofqual: ‘Mae’r graddau a ddyfarnwyd ar gyfer modiwlau Mehefin yn gywir, ond mae’n anodd eu cysoni â chanlyniadau mis Ionawr’.  O ganlyniad i’r casgliad hwn, ni argymhellodd Ofqual y dylid ailraddio’r cymwysterau ond, yn hytrach, y dylid cynnig cyfle unigryw ac eithriadol i ailsefyll yr arholiad ym mis Tachwedd 2012.
Ofqual undertook their own investigation into GCSE English awards in 2012 in England and published their preliminary findings on Friday 31 August. Ofqual expressed the view that ‘grades awarded for the June modules were right, but it is hard to square them with the January results’.  As a consequence of this conclusion, Ofqual did not recommend that the qualifications should be re-graded but rather that candidates should be offered a one-off and exceptional re-sit opportunity in November 2012.
