Hogg has been at the helm of the age-grade side since his appointment last October, overseeing the 2019 U20 Six Nations campaign and the coming championship in Argentina, after which he will move to Swansea.



Hogg said: I’m excited by the challenges that lie ahead next season with the Ospreys, but I also understand my responsibility and loyalty to the Scotland U20 players to ensure this World Rugby U20 championship is as successful as possible.



“There is no doubt we’re in a tough group alongside South Africa, New Zealand and Georgia but sport is all about taking your opportunities and turning the odds in your favour.



“I look forward to leading this great group of young men into the contest.”



The former Melrose, Leeds and Scotland back-row spent twelve years coaching in the English Premiership, having started his coaching career at Leeds alongside former England Head Coach and current Leinster Senior Coach, Stuart Lancaster.



After spells at London Welsh and Edinburgh Rugby, Hogg joined Gloucester as forwards coach in 2006 and was named Head Coach of Worcester Warriors in 2013, before touring with the senior Scotland team last summer and joining the age-grade set-up.



Scottish Rugby Technical Director, Stephen Gemmell, added: “I’d like to thank Carl for his work with the squad to date and in advance of next month’s World Rugby U20 Championship.



“While it’s disappointing to see any member of staff leave the set-up it’s pleasing to see another Scottish coach operating within the Guinness PRO14.



“We wish Carl all the best in his new role and with the season coming to an end. We'll now take time to review all of our programmes and to consider how best to move forward for the season ahead.”
