At SDTA, we research the systems that shape life for California's self-advocates and families, and we publish what we find.


Some content is presented as a searchable databases used as reference tools. Some of our research is analysis tied to a specific policy moment, like our review of DDS's proposed "cost-effective" definition and the record of what the community said about it in two DDS webinars. Some of our research content is about listening to the community we serve.  Our quarterly reports on what families are telling us directly, and research on what builds trust between families and the agencies that serve them are examples.


All research draws on the following elements:


  • Information that's publicly available 
  • Feedback we hear from the community
  • Facts we can source and reference


We always do out best to publish our method next to our conclusions, not just the numbers. If you think any of our research is wrong or out of date, please contact us.

DDS Directive Explorer

The DDS Directive Explorer is a searchable database of all 327 substantive DDS directives, guidance documents, and regional center correspondence from March 2020 through June 2026. Each entry carries SDTA's own triage notes on whether and how it matters to families, and you can filter by topic, document type, status, and more.

SDP Fair Hearings Explorer

The SDP Fair Hearings Explorer is a searchable record of 170 California SDP fair hearing decisions, coded by issue type, outcome, statute cited, and regional center. Families are denied outright 75% of the time and win full relief in only 15% of cases, with the worst odds on budget-increase and equipment requests.

Cost-Effective Definition Meeting Companion

The Cost-Effective Definition Meeting Companion is an 8-topic briefing built for the DDS committee writing the new statutory definition of "cost-effective" under AB 143. It covers what's changing, how other states define the term, what the fair-hearing record already shows, and SDTA's five-part counter-proposal.

What the Community Said: The Comments (companion volume)

SDTA's summary of 584 attendee comments from two DDS webinars (June 29-30, 2026) on the proposed cost-effective definition. Families and service providers, despite sitting on opposite sides of the same pay question, arrived at the same conclusion: not one comment in either session defended the proposed rate cap.
