The 18-year-old, who is the younger brother of Exeter Chiefs and Plymouth Albion rugby player Jack, is one of just 21 athletes named in the squad for the event in Stadskanaal.
Arnott won two bronze medals on his debut at the World Junior Games last year, competing in the under-23 category instead of his own under-20 age group.
He will be hoping for similar success this year in Holland between July 2 and 8.
The teenager competes in the T46 category, which is for athletes with upper limb disability.
Arnott was born with Erb’s Palsy, which means he has restricted movement in his left shoulder.
His dream is to compete at the Paralympics and those athletes selected for this championship are ones Team GB see as possible stars of the future.
Paralympic head coach Paula Dunn said: “The IWAS World Junior Games offers a great platform for athletes to make that next step to the major senior championships.
“The likes of Hannah Cockroft, Mickey Bushell and Aled Davies have all won medals at this event and it has stood them in good stead in their transition to the senior GB & NI team.
“It is really encouraging to see so many athletes coming through the Paralympic pathway and I’m confident we will see some strong results in Stadskanaal this summer to follow up what was a successful IWAS World Junior Games in Stoke Mandeville last year.”
