Rams head coach Glenn Morrison has extended his contract with the club until the end of 2017.
Morrison enters his third season with the Rams, having joined at the end of the 2013 campaign, and the club have improved on and off the field during his tenure.
A delighted Morrison said: “We’ve played well and improved each year.
“I think the club chairman said on Sunday, that the club’s now not thinking about relegation at the start of every season.
“It is about achieving success and although we’ve done well I still think we want to do a bit better.
“I still think that there’s the potential there for the club to get even better.
“At clubs like Dewsbury it’s a lot of work and you come up against tough conditions.
“However I think I have come a long way and we’ve looked at maybe creating that second team and we’ve made big decisions at the club like bringing through the youth, there’s a lot of hard work gone into it and now we’re getting the gains of it.
“I’m delighted to extend my contract and excited about the challenges that are ahead of us.”
