Scotland Under-20 captain Tommy Spinks is among 15 new recruits named by Scottish Rugby as elite development players for next season.
Spinks, who returns north from London Scottish, is one of eight players joining Glasgow Warriors.
Seven go into the Edinburgh set-up.
"All of Scottish rugby will look for these talented youngsters to make the step up," said Stephen Gemmell, Scottish Rugby's head of performance development.
"You just need to look at Matt Scott and Dougie Fife at Edinburgh Rugby or Jonny Gray and Adam Ashe at Glasgow Warriors as examples of what players who really commit to the programme can go on to achieve."
Two more players are set to be named in the elite development programme in the near future, with both joining Edinburgh.
