Derek Adams, Neil Lennon and Stuart McCall have been short-listed for the Cheque Centre PFA Scotland manager of the year award.
Bosses from across the four Scottish leagues - as well as Scotland manager Craig Levein - voted for who they believe has had the best season, in what was a record vote.
The winner will be announced at Glasgow's Hilton Hotel on Sunday, May 6.
Lennon has already guided Celtic to the Clydesdale Bank Premier League title this term, while McCall's Motherwell currently occupy third spot in the SPL following an impressive campaign.
In the Irn-Bru First Division, Adams led Ross County to championship success, with the Highlanders set to make their debut in the top flight next season.
Dundee United striker Jon Daly, Rangers captain Steven Davis, Celtic defender Charlie Mulgrew and Kilmarnock forward Dean Shiels are all in contention for the player of the year award.
Prizes for young player of the year, Divisions one, two and three players of the year and goal of the season will also be handed out on the night, as well as a special Merit Award.
