Here is a problem with each community teaching whatever they think the kids need to know. What happens when that child is moved to a new community? At what level of math or science will they be at? Will they be so far advanced that they will be bored to tears and quit school or will they be so far behind that they would have to be set back a year or more and then they will quit school because their peers are ahead of them. This community decision making may be fine for elective subjects but not for the basic. Having spent my 12 years of school attending 23 separate schools, I can tell you from experience it is hard as heck to keep up and often once you fall behind due to a move, you never do catch up. Oh, and I spent the last 4 years in the same school so you do the math. I am fortunate I even graduated, along with thousands of other military kids who spent their lives following their dads from duty station to duty station.

Unless you know what you are talking about, you just haven't a clue.
