Welcome. First thing what you need from a preschool. If you are returning to work outside the home part or full time, transport, other committments. When you have done that consider whether he needs to go to preschool at all and if so what does he need out of it. Don't think to much of academics as there is unlikely to be a good match anyway. But don't put him in an academic preschool that goes at normal speed. Good luck.
