The Stradbroke High School pupil was one of nine boxers representing the nation in Russia as England enjoyed their most successful tournament to date.
For the 14-year-old, the trip was not as memorable as it could have been as he failed to follow up a devastating second-round stoppage victory in the semi-finals with a repeat performance in the 65kg final, falling to a narrow split decision defeat to his Russian opponent.
However, instead of wallowing in disappointment, Kerrison chose to focus on the invaluable experience of representing England, gaining a silver medal and now being ranked second in the European Schoolboy rankings.
“I may not have won but I look at it as the experience and the fact it will allow me to move on to bigger and better things,” he said.
“Just being over there was a massive thing for me and being able to represent England was a real honour.
“After having a brilliant feeling of winning the semi-final I thought the final was really close.
“I won the first round, lost the second and I think the third was split.
“To me the final decision could have gone either way but in boxing you have to take the judges’ decision and accept it.
“I always go into competitions aiming to win gold but I’ve come home with a medal for my country and ranked number two in Europe, so I’m very happy.”
For Mendham-based welterweight Kerrison, his latest medal success caps an impressive year in the ring that has seen him crowned National Schoolboy Champion as well as cementing his place in the national squad.
The youngster has highlighted the support network around him for his meteoric rise in the past 12 months as he targets further success in the new year.
“The last year has been absolutely brilliant for me with a national title and representing England,” he added.
“I moved to Lowestoft Amateur Boxing Club and from there I’ve been a lot happier.
“The support I have been given has been really appreciated and it’s made a big difference.
“To me, boxing is 75 percent down to mentality and with the positive attitude I’ve got through my support I’ve been rewarded with titles and being in the England squad.
“I just want to keep proving myself to everyone and this year has helped me to do that.
“My next focus is the national camps in Sheffield in January and national competitions before looking to move into senior boxing when I turn 15.”
He added: “Things are looking really good at the moment and I just want to keep going.”
