Former Wales fly-half Byron Hayward has succeeded Danny Wilson as Wales Under-20 coach.
Wilson guided his side to second place at the 2013 International Rugby Board Junior World Championship, where they
lost to England U20.
"It's... a big pair of boots to fill on the back of reaching the Junior World Championship final," said Hayward."
Mark Taylor (team manager) and Richard Hodges (backs coach) are joined by Ioan Cunningham (forwards coach).
Scarlets assistant coach Wilson's contract has ended and he will concentrate fully on his Parc y Scarlets job.
Wilson said: "It has been great for my personal development as a coach - the experience has certainly put me on the next step of the coaching ladder - and I've worked with some very good future Welsh internationals."
Hayward's playing career included Ebbw Vale and Llanelli, winning two Wales caps.
He moved into coaching with stints at the Steelmen and Sale Sharks before joining the Welsh Rugby Union's academy set-up.
"Pressure comes with success and that's what you thrive on as a coach," added Hayward.
"I don't see any reason we can't reach the last four again next year if we keep working hard with the new group of players and if we do that, anything can happen as we saw in France - and South Africa last season ."
Cunningham arrives via his forwards coaching role with Wales U18.
WRU National Performance manager Gethin Watts said: "Byron is a former international player and a proven professional coach."
"He coached Ebbw Vale before moving to Sale Sharks and for the past two years he has been a WRU academy skills coach working with the best young players in the Dragons region and as Wales Under-20 attack coach."
