DVR leverages long—term extended services that are funded by the Division of Developmental Disabilities Services or, for transition students and youth with mental health disabilities, the Division of Substance Abuse and Mental Health. By leveraging the long—term supports through DDDS and DSAMH, DVR is able to expand supported employment services to youth with the most significant disabilities. DVR also uses Title I funds to supplement Title VI funds for supported employment. When extended services are not available through the support of DDDS or DSAMH, DVR will support extended services for a period not to exceed four (4) years. During the four years of DVR—supported extended services, alternate sources of extended services supports will be pursued, including the development of natural supports.
