Papillon, my DD was born in Jan 03 and she started Prep last year and was one of the youngest in her class. I was concerned a little too as she never went to a traditional kinder, just did 2 full days of a kinder program at day care. Her carer said she was ready, I felt she was ready so off she went! She loved school, but took a bit longer than the other kids to pick things up, most of the other kids were already 6. She is now in Grade 1 and doing extremely well at school, at the level she should be and is surpassing the level she should be on for her reading which was one of the things she struggled with.

I work at a university and do some work with psychologists and primary school teachers. There is great school readiness guide which looks at what areas indicate when a child is ready for school. I can't recall if its a DEECD (Dep of Education and Early Childhood Development in Victoria) guide but you could just google "school readiness" and I'm sure there will be plenty to choose from.

Or some teachers on BB might be able to give you more advice?

Good luck!
