Scunthorpe have offered a new contract to defender Cliff Byrne, and first professional deals to trainees Josh Lillis and Ashley Allanson. Byrne, 24, joined the Iron in 2003 and has been offered a one-year deal, with a year's option in the club's favour.
Midfielder Allanson made one substitute appearance last season, which ended early when he fractured a cheekbone.
Goalkeeper Lillis, 17, has also been offered a one-year contract, and made the first-team bench last term.
