"...The plan is to bring the minimum age to the international events to 14 year-old by 2019.."
Will it be safe speculation that there will not be a primary vs secondary divisions?
Hope that's not the case. I love all those games, but particularly like onstage despite most of our students would rather do Maze | Line | Soccer, because they felt onstage was too wide open. I indeed think that's when the learning can be so much more dynamic, as it is like an independent project.
Because of that, in my opinion keeping the division between primary and secondary is important not to discourage the younger ones to do onstage.
Just a thought in case my speculation stated earlier is true.
