Scottish referee Mike Adamson will be involved at the under-20s Junior World Championships in Georgia in May and June.
Fellow Scot Charles Samson is also to be taking part as a TMO.
The nine referees, three assistant referees and three TMOs will officiate over the five match days in Tbilisi and Kutaisi.
England are the defending champions after winning the tournament on home soil in Manchester, while 2017 hosts Georgia will be eager to build on their 10th place finish on their Championships debut last year.
With the under-20 Championships showcasing the future stars of world rugby, the tournament is also a crucial pathway for match officials.
World Rugby High Performance 15s Match Official Manager Alain Rolland said: “I am really looking forward to working with the match officials for this year’s tournament in Georgia.
“This year will see four ex-professional players among the team, in addition to referees who are already involved in the PRO12, Aviva Premiership, Top 14 and Super Rugby.

“The tournament is seen as a pathway for the next generation of international players and for the referees it’s no different. Previous referees that have progressed into international test matches include Angus Gardner, Ben O’Keeffe, Paul Williams, Marius van der Westhuizen and Matthew Carley, to name a few.
“It’s also a great opportunity for our TMOs to experience a top-class tournament and get the opportunity to step up to the next level.”
