The perceived environment of special education classrooms for adolescents: a revision of the classroom environment scale.

The Classroom Environment Scale (CES), originally developed for use in traditional public school classrooms, was revised for use in special education classrooms. The scale, which assesses students' perceptions of various aspects of the classroom, was administered to students in 79 special education classrooms in 16 residential and day treatment schools serving special education students with behavior disorders and emotional disturbance. Psychometric analyses showed that only seven of the nine aspects of the classroom found in the original CES were reliably reported in special education classrooms. The revised scale was found reliable for use in special education classes in residential and day treatment settings.
