Fraser MacKenzie will continue as Scotland senior manager for the next 3 years.
MacKenzie led his Scottish side to an impressive victory over the Irish in Kilkenny in 2008.
He will be joined by assistant managers Drew MacNeil from Fort William and referee Charles Young from Ballachulish.
Kenny Ross, who captained the Scots in 2008, also joins the coaching team. Ross played for MacKenzie when he was Lochcarron first team manager.
MacKenzie is renound for his thorough preparation and he will have no doubt started to plan for this year's international already.
There has been no announcement regarding the Scotland U21 management team.
