Where can I find a chart showing the mean age for motor skills and age ranges for 1 or 2 standard deviations below this mean?
I know this is what the OT and PT's do when they evaluate for delays, but I'd like to be able to look at this myself. An independent OT and PT have said my DS (almost 4) is 1 to 2 SD below mean in motor skills. Some skills are better and some less developed. Private OT and PT are too costly. DS is being evaluated by the public school system, but he will not qualify for help through the school unless they see this as either an educational issue or see that he is 2 SDs below where he should be.
I want to make sure I am armed with all the info I can get when I go into the meeting with the school system. I feel like I'd be a better advocate if I knew more about what he is close to the mean with and what is lagging.
Anyone know where I can find something like this?
