Betsy, 38, joins from Fulham where he has spent seven years working within the club’s academy as their U15s and U16s head coach.
Prior to joining Fulham, he enjoyed a successful 15-year playing career, with spells at a number of clubs including Fulham, Bristol City, Woking, Wycombe Wanderers, Barnsley and Southend United.
Regularly working from the National Football Centre at St. George’s Park, Betsy will oversee a dedicated programme of international camps and fixtures for the U15s England squad. He will work closely with national coaches across all the age groups, particularly between U15s and U17s.
On joining The FA, Betsy said: “Representing England as a national coach at any level is the absolute pinnacle of the profession and I am absolutely delighted to be joining The FA.
“I’m really optimistic about the talented players we’re producing in this country and introducing them to the demands and challenges of international football, but we also want them to understand how special it is to play for England.
"The facilities and learning culture we have created at St. George’s Park is world class, and bringing the players in to that fantastic environment can only help their progress and development.
“I’ve been fortunate enough to have enjoyed seven fantastic years working within a truly brilliant football academy at Fulham with some outstanding people and I leave with a heavy heart, but this opportunity is something I couldn’t turn down. I can’t wait to get started in what is a wonderful opportunity for me.”
The FA’s head of development team coaching, Matt Crocker, said: “I’m really pleased Kevin is joining The FA. His reputation within youth development is excellent, and he is highly regarded within the industry as one of the best coaches in youth development.
“Kevin’s enthusiastic attitude and committed approach is clear to see and his warm personality working with players and staff will be welcomed, as we strive to achieve success with all of our national development teams.”
