In the United States, federal(~~federer~~) law requires public schools to provide special education services to children with any disability. Specialists commonly provide these services while(~~where have~~) the children attend(~~aim at~~) 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 Pennsylvania(~~Tanselinger~~) 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. Hillside administrators say the main goal is to prepare students to learn effectively in a regular school. Teachers and specialist(s) develop individual learning plans for the students, which is（a） something a public school may also do. Development director Kathy Greene(~~Cathy Green~~) says most students remain at Hillside for about three years before leaving (for) a regular classroom setting.
