Hi
You only need to register once the child has turned six, however, you may choose to register when your child is five turning six.

School kids seem to start at five...but many educationalists suggest starting boys at a later age.....it's a personal decision.

Maybe you could just pause to reflect for while - school/homeschool is mandatory until 17 years of age now (in NSW anyway) so you have plenty of time to find your angle....also....just because you choose not to register 'til he's six doesn't mean he won't be learning until then! Mostly, by the time I'd registered my 3 eldest, they were six or seven and doing year 1 or 2 stuff......so if I were you I wouldn't bother registering too early - it's just an unnecessary distraction.....do it when you need to......well those are my thoughts.

Good luck - it's quite an education, huh?

Have fun and all the best!
