Some folks say a kid whose born before 9/1/2009 whose in the 6th grade that plays 2027s is “playing up.”
This is technically true but what’s also true is the kid is playing on age as a 27. When moving down to 28 they are on grade but not on age.
You see it a lot with summer birthday 2009 kids.
Whatever you want to call it it’s playing down.
It is also not worth discussion because it’s the way it is and won’t change anytime soon. And even if it does this group of kids will be long since graduated.
* I realize the irony of my typing this post only to end by saying it’s not worth discussion. That’s BOTC for you. |
