The Academy won 22-0 to follow up impressive wins over Wales Under-18s, Scotland Under-18s and Japan High schools earlier in the season.
Academy manager Neil McCarthy says: “It is a fantastic result for the Academy and for the players that played. It is a reflection of the Academy and is very pleasing for everyone involved."
Manu Tuilagi opened the scoring with the first try of the game at Broadstreet, Coventry. Matt Everard and Jack Cobden added a try each while fly-half Rickie Aley kicked a conversion to put the Academy 17-0 ahead at half-time.
Back row forward Tom Armes scored the Academy's fourth try of the game after the break to complete the scoring.
