Crawley have offered new one-year contracts to youngsters Jonte Smith and Louis John.
Striker Smith has made four first-team appearances this season and is currently on loan with Eastbourne Borough, while defender John is on a scholarship loan at Bognor.
Manager Richie Barker told the club's official website: "We think a lot of both Louis and Jonte.
"They are still young and by no means the finished article, but they are two players who fit into what we are trying to do at the club which is to develop and work with good young footballers."
Barker has also confirmed youngsters Jon Dollery and Aaron Wickham will be released when their contracts expire on June 30.
