One of five booklets designed to help vocational education teachers and administrators relate more effectively to handicapped students in their classrooms, this booklet discusses the labeling dilemma to stress that the information presented is very general; general traits are outlined to characterize a group. In addition, the distinction between a person with a handicap and a person with a disability is discussed. Characteristics are described of the following groups: mentally retarded students, students with specific learning disabilities, emotionally handicapped students, hearing impaired students, visually impaired students, and orthopedically handicapped students. A self-test is included for pre- and posttest evaluation. (TA)
