If they are summer 03 then they are holdbacks
If they are born in the summer of 2003 and held off starting kindergarten, they are not holdbacks. If they are summer of 2003 born and repeated 6th grade and are well adjusted kids with good grades, they are holdbacks. Even the public school counselors recommend for immature boys born in the late summer to hold off starting kindergarten - no parents are not thinking about 6th grade lacrosse when starting kindergarten.
