The England Under-21 international is held in high regard by parent club Tottenham Hotspur, but they have allowed him to link up with Championship outfit Queens Park Rangers.
Carroll has taken the decision to step down into the second tier in an effort to find regular football.
At 21 years of age he needs to be playing if he is to kick on, and appreciates that he would have found himself on the fringes of things had he stayed at White Hart Lane.
Carroll said on his move: "I could have stayed at Spurs and sat on the bench but at this stage of my career I feel I need to be playing."
The promising midfielder would appear to be in fine form at present and is enjoying being part of Gareth Southgate's new-look Young Lions, with more emphasis being placed on possession football.
After starring for the U21s in a victory over Moldova on Thursday, he said: "I think the lads enjoy playing that way. Most of us play that way for our clubs, so it would be good to play the same way on international duty.
"That's certainly the way we play at Spurs and that's the type of football I enjoy."
