Having cut his teeth at Gloucester and Cheltenham, Sherratt spent four years at Worcester Warriors academy, before becoming an attack specialist for Bristol, Ospreys and Cardiff before being handed his first head coach role at the Arms Park just 20 months ago.
With his teaching background, Sherratt has gained a reputation as a man-manager, a motivator and a mentor for young players.
Last season alone, the likes of Cam Winnett, Mason Grady, Ellis Bevan, Alex Mann, Corey Domachowski and Keiron Assiratti, Evan Lloyd, Efan Daniel, Mackenzie Martin all graduated under Sherratt at Cardiff to the national team.
“He is very well spoken of, a real people-person and man-manager and we felt, right now, that was a really important criteria and meant his could hit the ground running in the middle of the Six Nations,” explained WRU chief executive Abi Tierney.
