The 35-year-old, who also represented Real Madrid and A.C Milan, is without a club currently after parting ways with Indonesian top-flight Persib Bandung.
“I felt very happy after Michael Essien told me that he has obtained his Uefa B license certificate,” Kingston told Ghanasoccernet.
“I was really delighted to hear the news because some of my former teammates at the Black Stars are shy to be on the touch-line but I believe such steps can help develop our football.
“I will urge most of my colleagues to go into coaching. People like myself, Essien, John Paintsil and my brother Richard [Kingson] will help the game grow because we are going to apply the experience we acquired during our active playing days," he added.
Essien, who is on a self-imposed retirement from international duties with Ghana, boasts of 58 appearances and nine goals with the outfit.
He now qualifies to coach any of the Ghana Premier League clubs.
