Some 31 new faces are included in the 91-strong selection of male and female players across the four regional academy centres, with 11 players joining the top 'contracted' tier of the structure to replace those who graduated into senior professional rugby last season.
Daniel Winning (Boroughmuir), Thomas Gordon (Currie), Glasgow Hawks pair Sam Thomson and Robert Beattie and Jamie Bhatti (Melrose) come in to the top tier of the set-up without previous involvement, while the progress of Luke Crosbie, Charlie Shiel, Cammy Hutchison (all Currie), Matt Fagerson (Glasgow Hawks), Jade Konkel (Hillhead Jordanhill) and Ross McCann (Melrose) is rewarded with promotion to the same, fully-contracted stage.
A further 26 players have been selected into the earlier 'supported' stages (one and two) of the programme to take the spaces vacated by those promoted through the system and others, who for a variety of reasons, are no longer included.
Scottish Rugby Head of Academy and Performance Programmes, Stephen Gemmell, said: "Each of the BT Sport Regional Academies were required to provide evidence-supported nominations at a series of selection meetings over a period of months. The players were then considered within a national framework to finally arrive at the 91 announced today.
"Obviously the here and now plays a part in selection, such as the individual's skill set and match performances, but we also need to select players we think can play the game of tomorrow. It's about future-proofing the game in Scotland.
That's what makes the academy vital. It's about continually producing players that can go on and be influential in professional and senior international rugby in years to come by displaying a point of difference - be that physical, mental, technical or tactical - alongside their core rugby competencies.
"There's a whole range of factors that are taken into consideration but ultimately it's about who we think can follow in the footsteps of the nine players who graduated from the academy last year into the senior professional ranks."
The BT Sport Scottish Rugby Academy represents the nation's most promising male and female rugby players, with those named today the second tranche of inductees since the governing body's investment announced last year, in partnership with four regional centres in Aberdeen, Cumbernauld, Edinburgh and Galashiels.
The BT Sport Academies focus on three pillars of player development: high performance behaviours, rugby skills and athletic capacity.
These include but are not restricted to an athlete's training history and work ethic, and technical proficiency and consistency in skill delivery, while ensuring they are physically and functionally capable, self-sufficient and self-aware.
Developing the players' leadership, accountability and responsibility is also crucial to the system, with contracts structured to allow broader employment or study to help produce more rounded athletes with a secondary career option, should they fail to meet their professional playing ambitions.
Gemmell added: "The biggest thing is that, a year on from their launch, our four academy centres are now fully up and running, with our partnerships giving us outstanding facilities to ensure that the players don't have any excuses.
"The staff, the players, the parents and partners, all have a better understanding of what it takes to achieve success. Have we made improvements? Absolutely. But we're nowhere near the finished article in terms of what the BT Sport Academy can deliver for rugby in Scotland.
"We're now better equipped to support our players. The challenge is to make sure that continues while ensuring we take advantage of the improvements being made in the domestic club and school game, as part of a Scottish rugby-wide process that's continually evolving.
"The challenge to staff, players and stakeholders to innovate and find solutions to issues that continually arise to help us produce players for tomorrow.
"We need to work closely with our clubs and schools to continually support the development of the individual players, whilst always ensuring that they get the benefit of having better equipped players playing for them."
