I have a 2e child too. I would suggest looking at subject acceleration. With motor delay (or any 2e concern), I am hesitant to grade skip within bricks and mortar school setting. However, there comes a point when the grade skip acceleration is necessary.
My strategy has been to delay grade skip in braicks and mortar setting until my son would be in high school. This has a lot to do with the way they subject accelerate their middle school students into high school classes.
A young student in high school math is a lot different in my opinion than a Kindergartener with motor delays in 4th grade. Does that make sense?
My current opinion (in the middle of this journey with DS10) is in elementary grades to accerelate only the minimum amount to keep the child engaged. I think acceleration is most necessary - and most difficult - in elementary years. Don't feel like you need a long-term educational plan yet. Take it one semester at a time and pick whatever schooling option is the current best fit.
