Former Scotland midfielder James Morrison has joined Steve Clarke' coaching staff permanently after helping the national side reach their highest world ranking since 2017.
The Scots have moved up six places to 30th after four consecutive Euro 2024 qualifying wins left them eight points clear at the top of their group.
Morrison had helped prepare the team for wins over Norway and Georgia.
Scotland reached 29 in the Fifa rankings six years ago.
That came despite failure to qualify for the 2018 World Cup finals, followed by the resignation of Gordon Strachan as national boss.
