St Mirren's Stephen Robinson is the only non-title-winning boss among the four nominees for the PFA Scotland Manager of the Year award.
The Northern Irishman has been shortlisted alongside Celtic's Ange Postecoglou, Dunfermline's James McPake and Stirling Albion's Darren Young.
Robinson has earned recognition for leading St Mirren into the top six in the cinch Premiership this term for the first time since the split came into play more than two decades ago.
Postecoglou, meanwhile, has guided Celtic to back-to-back top-flight titles.
The Australian's side are in contention for a domestic treble, while they are also on course to pass the 100-point mark and have already scored more than 100 league goals.
Robinson and Postecoglou are the only two Premiership bosses in the running for the accolade, with the other two contenders coming from the lower leagues.
McPake marked his first season in charge at East End Park by leading Dunfermline to the cinch League One title, finishing 14 points ahead of nearest rivals Falkirk and losing only one of their 36 league games.
Young steered Stirling to League Two title glory.
The Binos finished 11 points clear of second-placed Dumbarton, with a 19-game unbeaten run in the second half of the season underpinning their surge to automatic promotion.
