Wakefield, bottom before Easter when Chester was appointed, are now sixth, just four points outside the top-four and five ahead of Hull KR, who are ninth.
Following yesterday’s win over leaders Warrington Wolves, Chester said: “I didn’t envisage this when I took over.
“It has been a great journey and a great ride we are on.
“I knew they had the quality of players available and we just needed to get these guys to start believing in themselves.
“We have turned over a few teams at home, some top teams. It is all about being consistent now and making sure we match that home form when we go away.”
Wakefield led 30-6 just after half-time, but Warrington cut the gap to four points before Ben Jones-Bishop clinched the result two minutes from time.
Wildcats had three players sin-binned in the second half and Chester said: “All credit to the boys, it was a very, very courageous performance.
“They dug in when they needed to. The amount of possession Warrington had in the second half, they really gave it to us, we we just kept turning up for each other.
“We were very, very good without the ball in the last five-10 minutes. I am very, very proud of the boys.
“It was probably the most courageous, spirited performance from a group of players I have seen in a long time.”
Wildcats scored four tries before the break and Chester added: “I thought we were very good before the break.
“We were the better team in the first half and Warrington were the better team in the second half.
“We created some fantastic opportunities and scored some really good tries. In the second half we started pretty slow and our contact wasn’t great, but I’m delighted we got the result.
“I wasn’t feeling very confident with five minutes to go, but credit my boys. They defended very well in those five minutes and deserved the win.”
