Hmmm - I was told a couple of years ago that the ESRFU and the RFU were in the process of harmonising the rules, however the major exception is that all schools who start at 11 years old tend to go straight into 15 a side and miss out on the 'u12 year'.
I was told this is effectively everybody playing u13 rugby early and was seen by the RFU as a 'block' age dispensation!
Will it ever merge ......
Actually these are largely the traditional grant aided and grammar schools which do 11 plus and start at 11 rather than the pure private 'public school' system which mostly starts at 13.
Unfortnuately I don't see any sign of the laws harmonising....
state sector obvisously go from primary to secondary at 11.
- in primary schools I have only ever seen tag played (I think primary schools see contact as a bit scary to train and play)
- in state secondary schools RFU U19 regulations are played BUT
independent sector have prep schools where contact rugby is played
- traditional independent secondary schools start at 13, especially the out of town boarding schools
- but starting at 11 is increasingly common and many of the day schools in London take most of theor pupils at 11
- in the independent sector a lot of 15-a-side rugby is played from a very young age - eg U10 U11.
- things don't really harmonise until U13 when everyone is playing 15-a-side.
I reckon the the UK there are currently EIGHT different sets of Laws used for rugby being played by 11 year olds
- tag rugby in state primary schools in England
- 15-a-side rugby in independent schools in England
- 13-a-side midi rugby in clubs in England
- experimental midi ruby in Hampshire/Warwickshire/Durham
- WRU Pathway rugby in Wales
- SRU Scottish rugby in Scotland
- Irish equivalent in Northern Ireland
I am not sure what welsh and scottish and Irish schools do -- perhaps there are three additional codes?
