Nigel Pearson and Sean Dyche are among the nominees for the Championship Manager of the Month award for April.
Pearson guided Leicester City to the title and a return to the Premier League for the first time in 10 years as the Foxes picked up 14 points from a possible 21.
Meanwhile, five wins and one draw saw Dyche's Burnley secure their place in the top flight for next season.
Brighton & Hove Albion's Oscar Garcia is also nominated after steering the Seagulls to the cusp of the playoffs. A highlight for the club was a 4-1 win at champions Leicester.
Millwall boss Ian Holloway completes the shortlist as an unbeaten month saw the Lions give themselves a big chance of avoiding relegation.
The winner of the award will be revealed on Friday morning.
