Bradford have given new deals to centre Jason Crookes, prop forward Steve Crossley and loose forward Danny Addy.
Crookes, 20, Crossley, 21, and Addy, 19, have all agreed two-year contracts.
Bulls acting head coach Lee St Hilaire said: "We are delighted that all three players have signed new contracts with the club.
"They are all developing well and we are confident of them improving even further during the length of their contracts here."
He added: "It's important that we keep our most promising players and reward them for the progress they are making."
Crookes made his Bulls debut in 2009 and has made eight appearances for the club while Crossley played in seven games last season after featuring in the England academy tour to Australia in 2009.
Addy was brought into the first team squad at the start of the year, shortly after signing a two-year contract and figured in 12 games for the club last season, scoring two tries and kicking two goals.
