Head coach Steve Clarke will lead Scotland in the Euro 2024 qualification campaign after extending his contract.
Clarke steered Scotland to this summer's Euro 2020 finals, a first major tournament in 23 years for the men's national team.
The 57-year-old's deal was due to end after the 2022 World Cup in Qatar.
Clarke said: "I am committed to helping us return to a major tournament as quickly as possible and improving on what we have achieved until now."
Clarke has also revamped his coaching staff, with Austin MacPhee and Chris Woods joining as Stevie Woods and Steven Reid step down.
Reid departs for family reasons, while goalkeeping coach Woods leaves to focus on his club commitments with Celtic.
He is succeeded by former England and Rangers goalkeeper Chris Woods, with MacPhee having relinquished his role with Northern Ireland. John Carver remains Scotland's assistant head coach.
Scottish FA chief executive Ian Maxwell says it "made sense on all sides" to extend Clarke's contract after he brought "success and stability to the national team".
Scotland resume their World Cup qualifying bid next week with a triple-header against Denmark, Moldova and Austria.
Clarke added: "I would like to thank Steven Reid and Stevie Woods for their contributions to the national team, not only during the summer but especially in my early months in the job, when we had some tough times and results."
Meet Clarke's new coaches
Former Hearts assistant MacPhee, 41, worked initially with Michael O'Neill as Northern Ireland reached Euro 2016. He stayed on as part of Ian Baraclough's staff, but will now work for his home country's national team.
He joined Aston Villa recently as a set-piece coach, after a spell as assistant manager of FC Midtjylland.
"A new opportunity has presented itself with my home nation and it is one I couldn't turn down," MacPhee said.
Chris Woods, a four-time Scottish title winner with Rangers, spent 15 years as goalkeeping coach at Everton before spells with Manchester United, West Ham and the USA national team.
Clarke says 61-year-old Woods' "wealth of experience" will benefit Scotland, as will MacPhee's "approach to coaching on the field and use of data off it".
