Chesterfield boss Paul Cook saluted his side's resilience after a 1-0 victory at Dagenham produced a first maximum points haul in four games.
The Spireites secured their first away win of 2013 thanks to an early own goal from Abu Ogogo.
Cook said: "This is always a tricky place to come to so I'm really pleased to come away with three points.
"It wasn't the prettiest of games but we've shown good heart and resilience and come through a really stern test.
"We could have been a bit more clinical, maybe tested their keeper a little more, but I can't be critical at all after an away victory."
Dagenham interim manager Wayne Burnett refused to criticise his players despite them now being on a run of just one win from eight games.
He reflected on a hectic few days in charge since taking over from John Still, who switched to Luton on Monday.
Burnett said: "It's been a big step up for me but it's been great to have been given the opportunity. Time will tell how things work out, but I came here five years ago thinking I could potentially end up in this position.
"So far I've seen good signs despite only picking up the one point from two games.
"I took some good advice from a number of people in the game before I did step in, and I think I am ready to do this now."
