Daeth yr adolygiad i'r casgliad na allai ymddygiad KW yn y dyfodol y tu allan i'w gyflogaeth fod wedi ei ragweld na’i atal. Fodd bynnag, mae wedi nodi nifer o faterion sylweddol o bryder a gwendidau’n ymwneud â llywodraethu, diogelu oedolion, recriwtio, diwylliant ac adrodd am ddigwyddiadau, gan ddod i'r casgliad fod sawl maes i ddysgu ohonynt ac i'w gwella. Mae cynllun gwella sy'n amlinellu'r camau sydd wedi eu cymryd hyd yma wedi ei gyhoeddi ar y cyd â'r adroddiad.
The review concluded that KW’s future conduct and behaviour outside of his employment could not have been predicted or prevented. However it has clearly identified a number of significant issues of concern and weaknesses relating to governance, adult safeguarding, recruitment, culture and incident reporting and concluded there were several areas for learning and improvement. An improvement plan outlining actions taken to date has been published alongside the report.
