Taking place between 17 October and 8 November at venues in in the cities of Chillán, Concepción, Coquimbo, La Serena, Puerto Montt, Santiago de Chile, Talca and Viña del Mar, the appointment is the latest boost for English officials
They will be joined in Chile by the England U17s squad, who qualified for the World Cup after their performance in last season’s European Championship, where they reached the quarter final in Bulgaria.
Speaking about the news, The FA’s Referee Committee Chairman David Elleray said: "The appointment of Michael, Stuart and Gary to the FIFA U17 World Cup Finals in Chile is another excellent achievement for English officials and shows once again how highly FIFA regard our referees and assistants.
"There is little doubt that Michael Oliver is one of the best young referees this country has ever produced and, along with Stuart and Gary, I am sure that he will prepare in the most professional way and will deliver a series of excellent performances when in Chile.
"The reputation of English football is regularly enhanced by the appointment of our match officials to the most important matches and competitions in the world and everyone at The FA will continue to support and appreciate what English match officials do."
They will play two games in Coqimbo and one in La Serena.
