Manager Gary Simpson told the club website: "It's great news we've been able to extend the deal.
"It's also a big vote of confidence for the football club given Everton are happy for him to stay. So we must be doing something right."
He added: "He's a likeable character who's got bags of enthusiasm and he's fitting in really well at the club.
"I believe he's growing stronger with each game and I'm confident there is more to come as he's still a young lad and learning all the time."
