Allardyce said that recent talks, which ensured his stay for the 2014-15 season, went well and that everyone involved with the club has their sights set on a strong year.
"The past is the past, you can't change anything - the crucial thing is to learn from it," Allardyce told the club's official website. "I am happy and proud to continue for another season as West Ham manager.
"I have had good, fruitful meetings with my employers and we are all in agreement that we want to move this great club forward in a united way. To that end we - the board, the staff, the players - are unified in wanting to create an exciting team for next season, one that is going to be better than last season.
"We want to try and achieve at least what we did in the first year back in the Barclays Premier League, which was a top-10 finish."
Allardyce has been in charge of West Ham since 2011.
