Re: Parents
You would hope most parents would. However there is only a window of two months to make secondary applications and four and a half for primaries. Those periods are spelled out in law and we can't change them. In year applications such as when moving into the area work differently since clearly they can happen at any point.
In practice you'll have three basic categories of parent - perhaps a quarter will be eager and looking into this as soon as they are out of the maternity ward, half will need a reminder that it is time to put an application in and the remaining quarter need prodding and poking all the way. As a county we still have hundreds of children not in school and even prosecution doesn't always help.
