From my experience as a parent of a child with special needs and past PTA president the first step with learning disabilities is getting your child diagnosed. Once they have been diagnosed the public school system will set up an IEP (Individualized Education Plan) to address your child's special needs. It is still up to you to be involved and when necessary advocate for your child.
To find out how the school has performed in standardized tests look on the school board website http://www.ocps.net On the bottom of that page, in the middle is quick links, 2008 school grades. The grades have not come in yet for 2009. Please keep in mind that these tests are not perfect indicators of the school's ability to meet your individual child's needs. I would encourage you to talk to the principal of the school as well and to visit the school.
Best of luck,
