The club are looking to get the most out of their new defender.
The Gers completed their second signing of the summer this week when they sealed the transfer of the former Republic of Ireland Under-21 defender from Wigan Athletic, and he joins Danny Wilson at the club as a genuine attempt by new boss Mark Warburton and assistant David Weir to strengthen the club's defence ahead of the new season.
And Weir revealed that the fact Kiernan is familiar to the duo through shared time at Watford and Brentford earlier in his career will help them do whatever it takes to encourage the player to reach his potential
"He's had great experience at a variety of clubs and experiences and levels," Weir said in the Evening Times. "But last season we have seen him quite closely and worked with him and obviously Mark knows him from way back.
“So there's a lot of work gone into it and a lot of different experiences but I think they are all positive and they are all things that can make him into the player we want him to be and he's shown to be very recently.
"He's good on the ball which is obviously important in regards to the modern defender but he's also a good size, he's athletic, he can use both feet. He genuinely has got a lot of really good attributes."
The former Scotland international did urge caution at initially expecting too much of the player though, stating that he has room to improve and assuring Rangers fans that the coaching team will be doing whatever it takes to do get the 24-year-old going in the right direction.
“He's not the finished article, he needs to get better at some things which we all do," Weir added. "That's part of our job is to try to improve the players and make them better and add value to them and to the football club.
"But he genuinely has, he is young and he's eager to learn and he’s definitely got room for improvement. But he's also at a good level right at this minute."
Kiernan was on loan at Birmingham for the second half of last season, making 12 appearances and scoring one goal, and he also had a short spell at Kilmarnock earlier in his career when he was just 19-years-old.
