Mae adroddiadau arolygu'r Awdurdod yn seiliedig ar y safonau nad ydynt wedi eu bodloni, a dim ond y safonau hyn sy'n cael eu cynnwys ynddynt. Os bydd yr Awdurdod yn barnu bod safon heb ei bodloni, bydd lefel y diffyg yn cael ei chategoreiddio fel difrifol iawn, sylweddol neu lai difrifol. Os bydd safonau'r Awdurdod wedi eu bodloni, ond bod yr Awdurdod wedi nodi y gellid gwella arferion, rhoddir cyngor ar hynny i'r unigolyn dynodedig.
The HTA inspection reports are exception-based: only those standards that have been assessed as not met are included. Where the HTA determines that a standard is not met, the level of the shortfall is classified as ‘Critical’, ‘Major’ or ‘Minor’. Where HTA standards are met, but the HTA has identified an area of practice that could be further improved, advice is given to the DI.
