The purpose of this study was to investigate on the actual conditions and needs of assistive technology(AT) support by special educational institutions. To meet this purpose, we conducted questionnaires on 17 provincial offices of education, 176 special education support centers, and 167 special schools personnel in charge of AT support. According to the results of the survey, provincial offices of education provided 48% of the AT budget as an external fund. In addition, special education support centers and special schools have received most of their budgets from senior agencies, and all institutions have used more than 98% of their budgets for purchase, maintenance and repair of AT devices. Device purchases tended to purchase intensively at the end of the year. The provincial offices of education and the special education support centers are in the process of establishing an AT support plan, but about one third of the special schools are still doing AT support without an annual plan. In addition, about 80% of the AT managers did not complete the related training and it was difficult to expect professional support. The demand for AT support was high in teaching - learning, communication, mobility, and posture maintenance. The AT staffs needed support for evaluating equipment selection, opportunities for training, AT device purchasing and utilization information, and systems for device management. Based on the results of the above research, we proposed the contents and composition of the assistive technology support system which is connected with on-line and off-line.
