IDEA Disability Categories in New Mexico

What disability categories qualify for an IEP in New Mexico?

New Mexico recognizes all 13 federal IDEA disability categories under NMAC 6.31.2.10, plus the state-authorized classification of Developmental Delay for children ages 3–9. The 13 federal categories are: autism, deaf-blindness, deafness, emotional disturbance, hearing impairment, intellectual disability, multiple disabilities, orthopedic impairment, other health impairment, specific learning disability, speech or language impairment, traumatic brain injury, and visual impairment including blindness (34 CFR 300.8; 6.31.2.10 NMAC). New Mexico uses the standard federal terminology for all categories — there are no renamed categories unique to New Mexico. The Developmental Delay classification applies to children ages 3 through 9 who demonstrate documented delays of at least two standard deviations below the mean on a standardized assessment or 30% below chronological age in one or more of five developmental domains: communication, cognitive, physical, social/emotional, or adaptive development (6.31.2.7 NMAC). Children using the Developmental Delay classification must be reevaluated during the school year they turn nine to determine eligibility under a specific disability category. New Mexico defines dyslexia in its regulations as a neurological condition characterized by difficulty with accurate or fluent word recognition and poor spelling and decoding abilities attributable to phonological language deficits — this definition informs identification practices for SLD but does not create a separate eligibility category (6.31.2.7 NMAC). For Specific Learning Disability identification, New Mexico uses a dual discrepancy model incorporating MTSS data (6.31.2.10 NMAC). A child may not be found eligible for special education if the primary determinant is lack of appropriate instruction in reading or math, or limited English proficiency (34 CFR 300.306(b)).
