Quins' George Merrick, Kyle Sinckler and Sam Twomey have been named in England's 31-strong Under 18 Conference squad to prepare for this season's international programme.
There are four survivors from last season's Under 18 Six Nations Festival side in fly half George Ford (Rishworth & Leicester Tigers), flanker Billy Vunipola (Harrow & London Wasps), lock Sam Twomey (Dulwich College & Harlequins) and centre Jamie Elliott (Bedford & Northampton Saints).
Also included is centre Chris Elder (RGS High Wycombe & London Wasps), whose brother Peter was named in the England Under 20 Elite Player Squad earlier this month.
England are unbeaten at Under 18 level for the last two seasons and the coaching staff led by John Fletcher will develop the new team in the four Conference games against the Academy sides from the South West, London & South East, North and Midlands.
The selectors will also look at more players in the Divisional Championships in January before naming a 26-man squad to take on their Six Nations opponents.
A further international opportunity comes in December against the Australian Schools touring side.
England will also field an Under 19 team for two games this season against Australia Schools in December and France in April.
Venues for the internationals will be announced in due course.
