Son #1 and Son #2 both played up in club until high school. #2 made the switch to on age his freshman year with no hold back. #1 waiting until his 22 graduated before he dropped to 23.
All private and Catholic Schools have “holdbacks” No matter the schools location. Just not public school where you just manipulate the age your child enters the public school system. Every kid that leaves public school to enter high school should be held back at least three years in order to catch up academically.
Quite using the holdback system for your failure as a parent for not sending your kid to private school. Public school lacrosse no matter where have a very slim chance of playing D1.
