SDP is a voluntary Regional Center program that provides participants with an individual budget, which they use to purchase the services/activities/items and the care/support they need to carry out and achieve their Person-Centered Plan (PCP) and individual Program (IPP). For many this has been life changing because it provides more choice, independence, freedom and control for regional center clients and their families. For example, participants and families may purchase services from traditional providers or local businesses, hire support workers directly, or negotiate unique arrangements with groups and individuals in their communities. People with disabilities are in charge of their own lives, not the professionals or systems that support them.
