Marlboro schools are indeed a very good school district, rating very high in the state. The school district does specialize in Special Education. K-8 is Marlboro School District and 9-12 is part of Freehold Regional School District, all excellent. You can go to the Marlboro website to find more information http://www.marlboroschools.org.
