Scotland assistant coaches Jonathan Humphreys and Matt Taylor have both signed contract extensions.
Forwards coach Humphreys and defence coach Taylor have joined head coach Vern Cotter in committing themselves until the summer of 2017.
Cotter said: "Keeping both Jonathan and Matt involved is very good news for the national team, and for the development of future Scotland players.
"They are good people who have contributed a great deal towards the standards we set and the style we play, continually offering new and innovative ways to raise the bar for the Scotland team."
Taylor joined the Scottish Rugby Union in 2012, combining his role with the national team as Glasgow assistant coach.
The Australian said: "It's been an absolute pleasure to work with the national team and I feel that we've made massive strides in all the areas of our play.
"Our performances in the Rugby World Cup are a really good example of how this team is moving forward and I think there are bigger and better things ahead as we target the RBS 6 Nations over the coming years."
Former Wales captain Humphreys moved to Scotland in 2013 following a seven-year spell in the same role for Ospreys.
The 46-year-old, who also works closely with the BT Sport Scottish Rugby Academy, said : "I've really enjoyed my time in the role and it's great to extend my contract because there's bags of potential in this team.
"Over the next 18 months or so I believe we'll really start to see this team realise that potential; and it'll be hugely satisfying to be part of something that could be quite special."
Cotter signed a one-year extension in August, just before Scotland's impressive World Cup campaign. Resource coach Nathan Hines and recently-appointed backs coach Jason O'Halloran are also contracted until summer 2017.
