QPR have had a dramatic shift in policy since Jimmy Floyd Hasselbaink took charge, and they are now looking to become a club where young players can develop at.
The R’s had previously looked at bringing in experienced players to strengthen their first team, but they changed strategy in January.
QPR brought in the likes of Nasser El Khayati and Conor Washington from Burton Albion and Peterborough United, respectively, last month.
And Ferdinand has suggested that QPR could look towards the lower leagues to bring in more players in the future, although he insists that League One is not the only market they are targeting.
"I have read people saying we are just trying to sign League One players," he said. "That’s not the case. We are heavily governed by Financial Fair Play, which means those are the markets we have to look in now. What we are trying to do is attract players who want to advance their careers, and see QPR as a place where they can do that.
“We have signed players over the last two windows, and I have heard people questioning those signings, about whether they’re good enough.
“We know that some of these players need work, need developing. That’s what we are looking to do with them, that’s the process. And we have a manager here who wants to go onto the training ground with his team of coaches and improve his players."
QPR had previously been guilty of signing up players at the wrong end of their careers, and they were punished for it.
Rangers struggled against Financial Fair Play, and also failed to ever sustain themselves as a Premier League club.
The R’s are now aiming to cut their costs, as they adapt to life in the Championship, and there looks set to be a great amount of changes made in the summer.
QPR are currently in mid-table in the Championship, and they will need to make vast improvements if they are to build a side capable of challenging for promotion next season.
