Joe, It's called Hartpury College. Hardly really a school, more a rugby academy that sits between the state school system and a university. And they they are bloody serious!
These academies were generally created over the past 10 years I believe and seem to be doing a good job in developing the young talent that sits outside of the traditional 'private schools' over there. Historically the Private Schools over there of a similar ilk to the NSW / QLD GPS model, i.e Wellington, Harrow, St Pauls, Tonbridge, Sherbourne, Rugby, Marlborough, Radley (BTW sorry to miss any out!) etc have had very direct links / pathways to the professional RU clubs. This has not occurred so much in the state system. These academies seem to be bridging the gap.
I'm certainly no expert. U21 rugby over there has historically been regionally organised and plenty of talent used to go missing / never got recognised.
