The individual must have a developmental disability and mental retardation or a specific related condition. Related conditions are limited to cerebral palsy, autism (including asperger syndrome), seizure disorder, chromosomal disorders (e.g., Downs), syndrome disorders, inborn errors of metabolism, and developmental disorders of brain formation.

  • Is manifested before the person reaches the age of twenty-two (22);
  • Is expected to continue indefinitely;
  • Results in a substantial functional limitation in three or more of the following areas of major life activity: self-care, receptive and expressive language, learning, mobility, self-direction, capacity for independent living, and economic self-sufficiency; and
  • Reflects the person’s need for a combination and sequence of special or interdisciplinary treatment, generic or other support and services that are of lifelong or extended duration and are individually planned and coordinated.
