Mae Bwrdd y Cynghorau’n cynrychioli lleisiau cleifion a’r cyhoedd ar lefel genedlaethol. Mae'n gosod y safonau cenedlaethol y mae'n rhaid i'r Cynghorau eu cyrraedd, ac mae’n rhoi cyngor, canllawiau a chymorth. Mae hefyd yn gyfrifol am fonitro a rheoli eu perfformiad.
The Board of CHCs represents the voice of patients and the public at a national level. It sets out the national standards CHCs must meet, provides advice, guidance and support and is also responsible for monitoring and managing their performance.
