The October 1999 edition of the excellent Four Four Two magazine focuses on Peterborough's flourishing youth policy and places the credit squarely on the shoulders of Kit Carson who joined the Posh from Norwich in 1993. Kit coached at Norwich for 10 years bringing through youngsters such as Ruel Fox and Chris Sutton. He was also heavily involved in the Canary Cup, a major youth tournament held each Easter at Great Yarmouth. Before his stint with Norwich, he worked in organising holidays for children.

As director of Peterborough's Football Academy, he was on a ten year contract as he was so highly valued by Posh manager Barry Fry. His conveyor belt of talent has brought 13 youngsters to international honours and many of them have broken into the Peterborough first team. These young talents include Matthew Etherington and Simon Davies (whom he snatched from Norwich) who had trials with Manchester United before joining Spurs.. Davies is only 19 yet has been called into the Welsh full squad whilst Etherington is already rated at £1.5million. Etherington made his league debut at 15 and has been selected for the Division Three representative side and England Under 20 side at the age of 17. Other talents include England Under 20 goalkeeper Mark Tyler, Irish under 21 winger Niall Inman, Welsh Under 21 leftback Gareth Jelleyman, Northern Irish Under 21 full back Gerald Lyttle, Irish Under 18 internationals Anthony Shields, Warren Kenna and Daniel Connor, Icelandic youth international Helgi Danielsson and Danish youth star Anders Koogi. Many of these players, and others, are on the brink of the Posh first team if they have not yet broken through. 25 youngsters followed Kit to Peterborough from Norwich according to an article in the Evening Standard on 10th February 2000.

Kit starts his work with the youngsters at the age of 9 and by the time they are 16, they will have been on more than 30 tours abroad. Kit values such trips as they play against Europe's leading clubs, develop loyalty and grow as responsible young adults. In training, he concentrates on technique above fitness and preaches that winning is less important than playing well. Kit seems dedicated to his job and has rejected two or three offers from Premiership sides. Norwich City could do with his talents.

Kit's future at London Road seemed vulnerable in May / June 2000 when he was alleged to have had a massive falling out with Peterborough's controversial manager Barry Fry. Tottenham were said to have noticed these developments and offered Carson an escape with a similar role at White Hart Lane. Although the problems were resolved, August 2001 saw Carson leave London Road with their Posh Academy downgraded to a centre of excellence due to financial constraints. Carson has been linked with a move to rivals Cambridge United to run their youth set-up following the defection of Ricky Martin to Norwich. This materialised on 7th November 2001 when Kit was appointed Cambridge's Head of Youth Development.

Following Cambridge's relegation to the Conference at the end of the 2004/5 season, United instigated a cost-cutting exercise which saw Carson leave the club. Kit then set up the Kit Carson Football Development Centre in Cambridgeshire and its teams have been an unqualified success with 9 of its graduates already gaining scholarships at professional clubs. Kit has established close links with his former player and friend Ricky Martin and already more young stars are in the pipeline ready to join the Norwich City youth team having graduated from Kit's Centre. In September 2005 Kit joined Chelsea as East Anglia Scouting Co-ordinator provided that his Centre retained its independence and that Kit continued to be its driving force.

In 2006, Kit joined Conference South side Histon as their Youth Academy Director. Kit commented “Histon excites me because it is a club going places with an incredible positive atmosphere throughout the club. I have had many offers both from home and abroad since I left Cambridge United but I have taken my time to reflect on what to do next. I have been working for Chelsea as East Anglia Regional Scouting Co-ordinator and I have also been running my own Football Development Centre with a fantastic group of local boys and their families and these lads will initially be the basis of the Academy. I want Histon's youth policy to be one of the best and rest assured it will be! We want it to be different with lots of new ideas and overall a scheme with which local players will be proud to identify.”

On 27th January 2017, Kit was arrested as part of the police invetigation into sexual abuse of young people within football. He was arrested on suspicion of indecency with children and indecent assauly. He had worked with Bob Higgins who was also named as a suspect in historical sexual abuse.

His trial was due to start on 7th January 2019 with Carson accused of 13 child sex offences, relating to 11 boys under the age of 16 between 1978 and 2009. On the day of the trial, his car crashed in a tree and Carson died of a traumatic brain injury.
