Derek Adams, Neil Lennon and Stuart McCall have been nominated for the PFA Scotland Manager of the Year award.
The trio, who manage Ross County, Celtic and Motherwell respectively, will find out which of them has been named as the season’s top boss on May 6.
Managers from all four of Scotland's senior leagues, including national boss Craig Levein, cast their vote in the awards.
Adams, who returned to County in May after a spell as assistant boss at Hibernian, has taken the Staggies to the Scottish Premier League for the first time in their history by winning this season's First Division title.
Celtic boss Lennon won his first SPL title since taking over at the club in early 2010, while McCall has steered Motherwell to third in the table and into contention of a place in next season's Champions League.
Dundee United's Jon Daly, Rangers' Steven Davis, Celtic's Charlie Mulgrew and Kilmarnock forward Dean Shiels are all in contention for the Player of the Year award.
Johnny Russell and Gary Mackay-Steven, both of Dundee United, Celtic's James Forrest and St Mirren's Kenny McLean are shortlisted for the Young Player of the Year prize.
