I have just read a post that may have cleared up a few things for me. Do you start at Preschool, THEN go to Kindergarten and into Grade 1? Over here (Australia) we have Kindergarten, THEN Preschool, THEN grade 1. Not sure why. We didn't have kindergarten for a while, and only brought it back in over the last few years. Our kindergarten and preschool are not compulsory, so not all kids attend. Starts being compulsory in grade 1. I think kindergarten is 4 half days a week, and preschool starts being full time. Some preschools may still offer part time, but I'm not sure. We have K to grade 7 in our Primary Schools and Grades 8 to 12 in our High Schools. Some Middle schools are starting to pop up with grades 7 to 10 (I think).
