OIS History

In 1989, the Oregon Department of Human Services (DHS) assembled a task force to develop a behavior intervention system that would be effective in keeping vulnerable individuals safe when they engaged in dangerous behaviors. DHS wanted a system that would utilize non-aversive techniques, avoid the use of punishment, and maintain the dignity of all individuals. After evaluating scores of different systems from across the United States, DHS determined that the system that most closely embraced Oregon’s values was Professional Assault Response Training (PART©). Dr. Paul Smith, founder of PART©, worked with professionals in Oregon to adapt his training curriculum to meet the specific Oregon Administrative Rules (OARs) for the populations which the new system would serve. Oregon’s original adaptation of the curriculum, PART-Revised (PART-R©) eventually evolved into PART-Oregon (PART-OR), which then evolved into OIS and became the official system delivering positive behavioral support to adults and children with I/DD.


Oregon’s efforts in behavior support promotes the Person-Centered philosophy and “Self-Determination” by emphasizing approaches which are individualized to the person receiving support and which value the person’s participation in the process of support planning.
