Carlisle has now been rewarded for his form this year with a new deal from Head Coach Richard Hill that will see his connection with the club continue until at least 2013.
The Warriors Academy product made his league debut for Warriors in 2008 before appearing off the bench in the European Challenge Cup final against Bath Rugby at Kingsholm.
The Swindon-born 23-year-old has firmly established himself in the senior side this season and made 23 league and cup appearances, including a stunning 28-point haul against Newport in the British & Irish Cup.
Head Coach Hill praised Carlisle's contribution this season and believes the young fly half has benefitted from working alongside the experienced Andy Goode.
"Joey is in top physical shape, is professional in all he does and has a fantastic skill set - he has it all," said Hill.
"He is a tremendous left foot kicker out of hand and excellent goal kicker; a superb passer of the ball off both hands and a silky runner.
"Importantly for a No.10, he has got the vision to give the ball to the right player at the right time. He puts us on the front foot when we attack, has a lovely show and go and can release the ball out of the tackle.
"Joey is a very hard worker and he works tirelessly on his game throughout the week. He is a lovely player to coach as he listens and strives to improve himself.
"He is learning how to manage a game depending on circumstance and position and that will come from playing every week and listening to people like Andy Goode.
"Andy can manage a game and makes the right decisions; clearly Joey is learning a great deal from working with him.
"There is no doubt Joey will get even better and is one of the most talented outside halves that I've ever seen. He will be, in the very near future, the player we know he can be and has made big strides this year."
