Eloquence is not my strong point when I first wake up :P but yes exactly that.
I wouldn't though put a child in school over my career. I just couldn't. I guess for me I've seen that happen. And children are rarely kept down these days (once they are in the system) with a fight unless there is extreme social concerns so I have seen children struggle academically/socially/emotionally who should have stayed home. And the social problems only arise in the second half of primary school and is directly related to confidence academically. And by then even choosing to keep them down at that point has social ramifications. Emotional maturity as well as social maturity are so important to me because for a large part of primary school these kids can coast until thy reach the second half of primary and then their confidence starts to break. And this impacts hugely in secondary school. And then you have the concerns of how well a child can handle the stress of exams and study in the final years. I have high school teacher friends who often comment on the emotional maturity being extremely obvious in the last 2 years and how that impacts greatly on how well they do. So for me even though I have a younger child I wouldn't hesitate in holding them back if it were necessary because it would feel to me like a short term solution with long term effects.
