Ym mis Tachwedd 2012, cyhoeddodd Arolygiaeth Gofal a Gwasanaethau Cymdeithasol Cymru (AGGCC) adroddiad am wasanaethau cymdeithasol plant yng Nghastell-nedd Port Talbot. Ynddo, nodwyd bod heriau sylweddol yn yr awdurdod, a dywedodd y Prif Arolygydd fod sail i bryderon difrifol, gan alw ar ddefnyddio'r protocol pryderon difrifol er mwyn cadw at yr ymrwymiad corfforaethol cyffredinol i wneud y gwelliannau sydd eu hangen.
In November 2012, the Care and Social Services Inspectorate for Wales (CSSIW) published a report about children’s social services in Neath Port Talbot. This identified significant challenges in the authority and the Chief Inspector identified grounds for serious concern, invoking the use of the serious concern protocol to secure the overall corporate commitment to the improvements needed.
