3 month vs. 12 month, the gap in sports development and learning. For example:
child born in February vs. December are in same class, early on there is gap in knowledge from experience and that gap is further expanded later in life such as sports, most professional hockey players are born in January -March. If a youth is more developed vs. younger counterparts then more instruction and development goes to older ones.
I think education system is no different. I would propose student classes year round but grouping students closer to a 3 month age gap vs. 12 month. Thoughts…?!?
