Outline of Final Research Achievements

In this study, I tried to show what the difference between the teacher and parents is and why the difference is produced when they evaluate adaptive skills of the students with developmental disabilities. The characteristics of the difference were almost supported by
preceding studies. The factors of the difference were the variability of behaviors, a lack of information about the child, and the vagueness of a meaning and the criterion of the item, the estimate in rating. When parents and teachers reevaluated a half year later, their results became closer to each other due to the enough information on the students, paying more attention to the insufficient adaptive skills, and the influence by the first result of parents. Generally the difference is considered as a problem, but it can develop the understanding of the students and the support that is necessary for their parents. These suggest how clinically meaningful the difference between evaluation of parents and teachers is.
