Commack is an EXCELLENT school district. They have a great Special Ed program.
Why dont you call, and ask any questions you may have ? You should actually start looking into it now if you do plan to move here, so that all paperwork is done and your child gets all services he deserves.
Here is the district website. Call the main number, and ask to speak to the Special Education Department.
