IDEA Disability Categories in Oregon
What disability categories qualify for an IEP in Oregon?
Oregon recognizes 13 disability categories for special education eligibility, consistent with but slightly differently labeled than federal IDEA categories. Under ORS 343.035(1), children qualify as having a disability if they meet criteria established by State Board of Education rules and have one of the following conditions: (1) intellectual disability; (2) deafness or hard of hearing; (3) speech or language impairment; (4) visual impairment (including blindness); (5) deafblindness; (6) emotional behavior disability (Oregon's term for emotional disturbance); (7) orthopedic impairment; (8) other health impairment; (9) autism spectrum disorder; (10) traumatic brain injury; (11) specific learning disability; (12) developmental delay (for children ages 3 through 9); and (13) specific learning disability—dyslexia is recognized under OAR 581-002-1800 as a neurobiological condition characterized by difficulties with accurate or fluent word recognition and poor spelling and decoding, which falls under specific learning disability (ORS 326.726; OAR 581-022-2445). Oregon uses the term 'emotional behavior disability' (EBD) rather than 'emotional disturbance,' which is an Oregon-specific terminology distinction. The developmental delay category applies to children ages 3 through 9 and may be used when a child has a delay but does not yet meet criteria for a more specific disability category. Oregon provides disability-specific eligibility forms for school-age students for each category. Children must both meet the disability criteria and require special education as a result of the disability to be eligible for services. Oregon's child find obligation requires districts to identify, locate, and evaluate all resident children who may have disabilities (ORS 343.157).
What Oregon Requires
Oregon recognizes 12 disability categories plus developmental delay (ages 3-9) under ORS 343.035(1), mirroring federal IDEA categories with Oregon-specific terminology.
Oregon uses 'Emotional Behavior Disability' (EBD) rather than 'emotional disturbance'—this is an Oregon-specific terminology distinction that must be used in IEP and evaluation documentation (ORS 343.035(1)(f)).
The developmental delay category applies only to children ages 3 through 9 (ORS 343.035(1)(l)); eligibility under this category lapses when the child turns 10, and the team must determine whether a more specific disability category applies before that point (OAR 581-015-2127).
Dyslexia is defined in Oregon law as a specific learning disability; districts must conduct universal screenings for dyslexia risk factors and provide evidence-based interventions (ORS 326.726; OAR 581-002-1800; OAR 581-022-2445).
To be eligible, a child must both meet the disability criteria and require special education and related services as a result of the disability—disability alone is not sufficient (34 CFR 300.8; ORS 343.035).
Oregon provides standardized eligibility determination forms for each disability category for school-age students (ODE School Age Sample Forms).
A child must not be determined eligible solely due to limited English proficiency, lack of appropriate instruction in reading or math, or cultural differences (34 CFR 300.306(b)).
Key Timelines
Eligibility determination must be completed within 60 school days of parental consent for initial evaluation (OAR 581-015-2110); Oregon measures this in school days, not calendar days.
Reevaluation to review eligibility must occur at least every three years, or more frequently if conditions warrant or parent/teacher requests (34 CFR 300.303(b)).
Developmental delay category eligibility lapses when the child turns 10 (the category covers ages 3 through 9 per ORS 343.035(1)(l)); the team must determine whether a more specific categorical label applies before that point (OAR 581-015-2127).
