And I, for one, don't think it should be. IMO - the decision should be removed from parents - a state/district should choose a cutoff - whatever that might be (make them all earlier if that will make people happy) - and then - if you're born before it - you go, if you're born on or after it - you wait till next year. This option provides the one thing many of the posts in this thread crave...an equal playing field for their child. NOTE - if there is an actual delay in some area in which professional assistance is being provided - this could allow a 'medical' holding back. But for those who just choose it because they want their kid to be older, know more academically, know more socially, be bigger for sports, to be a leader...I don't think it should be a choice.
What happens is that everyone starts holding their kids back - and then the teacher is put into a position to teach 4 year olds and 6 year olds in the same classroom. Difficult for the teacher? Yes. However, since it was the choice of the 6 year old parents to hold their children back with the intent that they would know more than others in the class - the teacher SHOULD only focus resources on the 4 year olds and 5 year olds - the ones going on time. OF COURSE 6 year olds will know more, be reading more, be doing more math...they've had a year plus more learning that the 4 year olds...however, here in NY 12/1 is the cutoff, and the curriculum should be focused on those that are going 'on time'.
And, where does it end? The August b-days will be held back, then the June/July b-days are now the youngest...then they get held back - now the April and May kids are held back...then they are youngest and the parents don't want that - so now Feb and March kids are held back....and so on - it's endless.
It does upset me while at the same time I totally understand why parents do it (no one wants the uncertainty of sending their child to school on their own for the first time) - because...it is because of parents who are sending their children on time that the kids of those held back actually get the 'benefits' - if everyone held their kids back for a year - your Sept b-day children would still be the youngest in the class. So you have those of us who send our kids on time to thank for it.
The decision should be removed from it. 4 year olds going on time should not suffer due to a teacher having to deal with 6 year olds in the classroom at the same time.
I think this will continue to be a debate until something changes.
Good luck with your decision.
