Projects
The California State Alliance Team (SAT) worked towards three primary overarching goals:

Goal 1
Establish a statewide community of practice with the mission to bridge intellectual and developmental disabilities (I/DD) and aging networks to support aging individuals with I/DD and their caregivers. The focus is on establishing a SAT with various knowledge, expertise, and commitment to bridge I/DD and aging networks.

Goal 2
Increase the availability of culturally and linguistically responsive services, resources, and supports for older adults with I/DD and their caregivers. Leverage existing resources and increase collaboration via culturally and linguistically responsive cross-training at the local level.

Goal 3
Increase the availability of future planning services and supports for aging people with I/DD and their caregivers. Create an inventory of culturally and linguistically responsive tools, best practices, and resources for future planning.
Highlights/Milestones Achieved
Creation of a Common Terminology Guide
The California State Alliance Team has developed a “Common Terminology” guide. Terminology establishes the precedence of policy and program practices. This is especially critical given that a primary goal of policy is to convey important information concisely and in a clear manner. While this remains a consistent practice in laws and regulations, there is often a need to identify common terminology within “Communities of Practice” that are relied upon to pilot emerging models and best practices. The California SAT identified the need to develop this terminology inventory within the goal of increasing access to age-related services and supports for aging individuals with I/DD and their caregivers. Currently in draft, the terminology inventory serves as a best practice resource for processes, program structures, and policies.
Addition of Aging-Related Questions and Prompts in Statewide IPP Template
The California Department of Developmental Services serves more than 450,000 individuals. California developed a new statewide, standardized Individual Program Plan (IPP) template and accompanying Service Coordinator Guide, which includes proactive approaches in addressing supports and future planning for individuals and their caregivers as they age. All Service Coordinators from the 21 Regional Centers across California are required to use this person-centered template and guide.
Incentivizing Aging Projects at Regional Centers
The California Department of Developmental Services incentivized Aging Projects at the Regional Centers[1]. California’s Community Placement Plan (CPP) and Community Resource Development Plan (CRDP) for Fiscal Year 2024-2025 developed priorities that included meeting individual and community needs of older adults with I/DD.
Aging Inclusion Resources
- The Department of Developmental Services (DDS) launched the Aging Inclusion Resources webpage on its website.
- This page serves as a hub for people supported, their caregivers, and professionals to find resources for services and supports. This page will continue to grow through the work of the State Alliance Team.
