Hi, i have a rising 6 yo child (been at school for 1.5 years) currently starting level 4 in this system. I cannot find any other schools using this system as my friends children all use Oxford Learning Tree. I just wandered if this was average for a 6 year old and how the levels would equate to approx ages. She hasn't been the quickest to pick up reading and I was just concerned in case she seemed behind.
