It is the third time Guernsey has taken on the honour of hosting the event, the previous occasion being in 2012, and the top local players will go up against some fine visiting opposition.
England are offering a full complement of 12 pairings across the three age groups, while Scotland, Wales, Ireland, Jersey and the Isle of Man will also provide varying levels of competition.
GTTA president Derek Webb predicts that the players and accompanying personnel will add up to a total visiting contingent of around 140.
While Guernsey are one team short of a full house, the hosts are very well represented across the three age categories.
U18 star Ben Foss has a previous medal to his name and the accomplished youngster will face tough opposition in the bid to earn another.
‘Ben has medalled before, so I am hoping he will do well,’ said Webb.
‘But it’s a tough tournament – we are playing against some of the best players in England and Scotland and all that.’
England will provide particularly daunting opposition, having swept the categories at the roll of honour last year in Worcester.
Play runs from 3pm on Friday and continues until Sunday afternoon at Hougue de Pommier.
