Serving Washington's DDA system means understanding the DSHS → DDA → CRM structure, getting certified under WAC 388-101, clearing Background Check Central Unit screenings, and training your direct support professionals on the state's 75-hour pathway — all in service of each client's Person-Centered Service Plan. Here is the whole path, in order.
Washington's I/DD system is run by the Developmental Disabilities Administration (DDA) inside DSHS, under Title 71A RCW. DDA's regional offices and Case Resource Managers (CRMs) handle eligibility, run the CARE assessment, and author each person's Person-Centered Service Plan (PCSP). Important context: DDA services are not an entitlement (RCW 71A.16.010) — eligibility doesn't guarantee paid services, which makes the funded clients you serve all the more carefully planned for.
DDA funds services through five 1915(c) waivers under chapter 388-845 WAC — Basic Plus, Core, Community Protection, Individual and Family Services, and CIIBS — plus Community First Choice personal care. Residential habilitation (supported living) lives on the Core and Community Protection waivers. Roads to Community Living funds transitions out of institutions. Which authority a client is on shapes exactly which services your agency can deliver and bill.
Supported living providers are certified (not licensed) by DDA under chapter 388-101 WAC — Certified Community Residential Services and Supports — with operating requirements in chapter 388-101D WAC. Expect certification evaluations, monitoring visits, and a complaint lane through the DSHS Complaint Resolution Unit. Adult Family Homes are a different path entirely: licensed under chapter 388-76 WAC. Know your lane — it determines your training track, your credential rules, and your oversight.
Long-term care workers are screened through the DSHS Background Check Central Unit with state and FBI fingerprint checks (RCW 74.39A.056). Disqualifying crimes live in chapter 388-113 WAC, along with Character, Competence and Suitability determinations for records that need individual review. A worker who clears the state check may work with supervision arrangements pending FBI results, per department rules.
Your staff are long-term care workers: 5 hours of orientation and safety before providing care, then 70 hours of basic training within 120 days — for supported living, the 40-hour DDA-developed residential curriculum plus 30 population-specific hours — plus first aid/CPR within 60 days and 12 CE hours every year. Community residential workers are exempt from Home Care Aide certification (RCW 18.88B.041). And before anyone works alone: training on each client's plans, emergency procedures, abuse reporting, and confidentiality (WAC 388-101D-0095) — see Washington DSP training requirements.
Every employee is a mandated reporter under RCW 74.34 — abuse reports go immediately to END HARM (1-866-363-4276), with law enforcement for sexual and most physical assaults. Provider incidents flow to DDA under Policy 6.12 on tight timelines. Daily documentation must implement each client's PCSP and individual instruction and support plans — the record certification evaluators and CRU investigators read first. Keeping all of it audit-ready is exactly what DSPlife™ TrainingHub handles — a ready-to-assign Washington course library, renewal tracking, and audit-ready records.
Supported living agencies are certified by DDA under chapter 388-101 WAC — staff support clients in homes the clients own or rent, and workers follow the WAC 388-829 training track (75 hours, HCA-exempt). Adult Family Homes are licensed residences under chapter 388-76 WAC, overseen by residential care services, whose caregivers follow the WAC 388-112A track and generally need Home Care Aide certification plus developmental disabilities specialty training when serving DDA clients.
Residential habilitation — including supported living — is a Core waiver service (and Community Protection for participants who meet those criteria). Basic Plus deliberately excludes residential habilitation; it funds community supports for people living at home. Community First Choice adds the personal-care layer across settings.
WAC 388-101D-0095 sets the gate: before working alone with clients, staff must be trained on each client’s current individual instruction and support plans, each client’s emergency procedures, abuse and neglect reporting under RCW 74.34, and client confidentiality. The 5 orientation/safety hours must come before providing any care, and the full 70-hour basic training is due within 120 days.
No — RCW 18.88B.041 exempts long-term care workers employed by community residential service businesses. They complete the 75-hour pathway (40-hour DDA curriculum + 30 population-specific hours) instead. Staff in DDA group homes licensed as AFH or assisted living generally do need the HCA credential.
Through counties — a structure nearly unique to Washington. DDA contracts with county governments under chapter 71A.14 RCW; counties subcontract to employment and community-inclusion agencies and handle planning, contracting, and monitoring. Day-program funding for working-age adults is expected to support employment or a pathway to employment.
