In the United States, federal law requires public schools to provide special education services to children with any disability. Specialists commonly provide these services while the children attend the same schools, and often the same classes, as other students.But today we look at three private schools that serve only students with learning disabilities.The Hillside School in p（Pennsylvania）accepts up to one hundred twenty-eight children. The students are ages five to thirteen. They have disorders with language, writing or working with numbers. They may also have attention deficit disorders.Each class has no more than eight students. H administrators say the main goal is to prepare students to learn effectively in a regular school. Teachers and specialists develop individual learning plans for the students, which is something a public school may also do.Development director K G  says most students remain at Hillside for about three years before leaving for a regular classroom setting.
