The purposes of this study were to explore the differences in internal-external locus of control between physically handicapped students and non-handicapped students and to investigate that if two different education programs (segregation vs. integration) would affect the locus of coatrol of the physically handicapped students. Two hundred and forty junior high level students were given the Nowicki-Strickland´s Locus of Control Scale. The subjects included three groups: (1) the physically handicapped students in special school, (2) the physically handicapped students in junior high school, and (3) non-handicapped students in junior high school. The results indicated (1) the physically handicapped students, both in special school and in junior high school, were more external than the non-handicapped students, (2) the physically handicapped students in special school had higher external scores than those in junior bight school, but the differences were not statistically signicant, and (3) no signicant sex differences were found.
