Your child is turning 18 and every agency is changing the rules at the same time
The Social Security Administration is switching your child from the childhood disability standard to the adult standard — and a meaningful share of reviews end in cessation. The Oregon Health Authority requires a separate Medicaid application through the ONE portal, even though your child has been covered under the family plan for years. The school district is transferring all educational and legal rights to a student who may not be ready to exercise them. And the Office of Developmental Disabilities Services needs your family to choose between county CDDP case management and a Support Services Brokerage — a decision that will shape every service your child receives as an adult.
No government office in Oregon coordinates any of this. The SSA does not notify ODDS when benefits are suspended. The school district does not alert OHA when your child ages out. The county CDDP does not check whether the OHP enrollment went through. You are the systems integrator — and right now, the operation has no manual.
The Transition Command Center: Every Oregon Agency in One Sequenced Workflow
This guide is the manual. It maps every federal and state agency your family touches — SSA, OHA, ODDS, the county CDDP, the school district, and Oregon Vocational Rehabilitation — into a single chronological workflow where each filing builds on the last. The guide does not recite eligibility rules you can find on five different state websites. It shows you the dependencies between agencies, the domino effects when one filing fails, and the precise order that prevents gaps.
What's Inside
- SSI Age-18 Redetermination Walkthrough — how the adult disability standard differs from the childhood standard, what evidence to assemble at age 17½, how to complete the Function Report with limitation-specific examples that demonstrate inability to perform Substantial Gainful Activity ($1,690/month in 2026), and the 10-day benefit-continuation window that keeps SSI payments flowing during an appeal
- DAC and Disabled Adult Child Pathways — how to claim 50% to 75% of a parent's SSDI work record as a derivative benefit, the marriage restriction rules, the onset-before-22 documentation requirement, and how the Social Security Fairness Act repeal of WEP and GPO restored full payment amounts retroactive to January 2024 for public-sector families
- Oregon Health Plan Transition Guide — why OHP enrollment is a separate filing from SSI (Oregon is an SSI-criteria state, not an automatic-enrollment state), how to navigate the ONE portal application, the SSI-related pathway versus the 300% Group for waivered services, the $2,000 resource limit, and the YSHCN 1115 waiver extending enhanced coverage for young adults aged 19–20
- ODDS Waiver and K Plan Enrollment — how to complete CDDP intake and the Oregon Needs Assessment, the eligibility criteria for the K Plan (unlimited enrollment, no statewide waitlist), the Support Services and Comprehensive 1915(c) waivers, and the Children's Extraordinary Needs Program waitlist for families transitioning before age 18
- CDDP vs. Brokerage Decision Workbook — a structured comparison of county CDDP case management versus the 14 statewide Support Services Brokerages, including caseload ratios (Brokerages cap at 45), service scope, and interview questions to ask before choosing an entity
- ABLE Account Strategy — the $20,000 standard annual contribution limit, the $15,650 ABLE-to-Work add-on for employed account holders, the $100,000 SSI resource exclusion, the ABLE Age Adjustment Act raising the disability-onset requirement from age 26 to age 46 effective January 2026, and how to open an Upward Oregon ABLE account
- Work Incentives Sequencer — the Student Earned Income Exclusion ($2,410/month for working students under 22), Section 1619(b) continued Medicaid, the Employed People with Disabilities program ($5,000 resource limit, higher income threshold), the Trial Work Period, and how Oregon VR's Work Incentive Planners coordinate state and federal exemptions
- Decision-Making Authority Selector — the precise legal differences between supported decision-making under HB 2105, durable powers of attorney, healthcare representative designations, and guardianship under ORS Chapter 125 — so you know which tool you need and which ones you can skip
- Graduation Pathway Calculator — standard versus modified versus extended diploma consequences, how each option affects FAPE through age 21, and SB 819 protections against unilateral shortened school days
Who This Guide Is For
- Parents whose teenager with a disability is approaching 18 and who need to prepare for the SSI redetermination, secure Oregon Health Plan continuity, and coordinate the ODDS transition
- Families who already received the age-18 redetermination packet and need to respond correctly within the 10-day benefit-continuation window
- Parents of young adults aged 18–21 still enrolled in special education who need to plan the school-exit-to-adult-services handoff before IDEA eligibility ends
- Families navigating CDDP intake and Brokerage selection while dealing with provider capacity constraints in their county
- Parents who assumed legal authority continued automatically at 18 and discovered that doctors, schools, and agencies now require formal decision-making documents
Why the Free Information Is Not Enough
FACT Oregon runs excellent workshops on IEP rights and advocacy, but their coverage focuses on K-12 systems and does not sequence the adult benefit filings. Disability Rights Oregon publishes legally authoritative manuals, but they are dense, academic, and organized by statute rather than by the family's real-life timeline. DB101 has solid benefit calculators, but they are nationally oriented and miss Oregon-specific details like the separate OHP application requirement, the CDDP-versus-Brokerage choice, and the K Plan's unlimited enrollment structure. Special needs attorneys can coordinate the whole picture, but initial consultations alone run $3,500 to $10,000 for guardianship filings and trust setups.
This guide organizes the verified pathways across every agency into one sequenced workflow — for a fraction of one billable hour.
