Disability Condition Eligibility Definitions

The IDEA and Texas Administrative Code (TAC) provide explanations of the criteria for disability condition determination.

Autism (AU)

A student with autism who has been determined to meet the criteria as stated in 34 CFR, §300.8(c)(1):

  • Autism means a developmental disability significantly affecting verbal and nonverbal communication and social interaction, generally evident before age three, that adversely affects a child's educational performance. Other characteristics often associated with autism are engagement in repetitive activities and stereotyped movements, resistance to environmental change or change in daily routines, and unusual responses to sensory experiences.
  • Autism does not apply if a child's educational performance is adversely affected primarily because the child has an emotional disturbance, as defined in paragraph (c)(4) of this section.
  • A child who manifests the characteristics of autism after age three could be identified as having autism if the criteria in paragraph (c)(1)(i) of this section are satisfied.

Students with pervasive developmental disorders are included under this category. The team's written report of evaluation must include specific recommendations for behavioral interventions and strategies. 

Deaf/Hard of Hearing (DHH)

A student who is deaf or hard of hearing is one who has been determined to meet the criteria for deafness as stated in 34 CFR, §300.8(c)(3):

  • Deafness means a hearing impairment that is so severe that the child is impaired in processing linguistic information through hearing, with or without amplification, that adversely affects a child’s educational performance.
  • or for students who are deaf or hard of hearing as stated in 34 CFR, §300.8(c)(5):
  • Hearing impairment means an impairment in hearing, whether permanent or fluctuating, that adversely affects a child’s educational performance but that is not included under the definition of deafness in this section.

The evaluation data reviewed by the multidisciplinary team in connection with the determination of a student's eligibility based on being deaf or hard of hearing must include an otological examination performed by an otolaryngologist or by a licensed medical doctor, with documentation that an otolaryngologist is not reasonably available, and an audiological evaluation performed by a licensed audiologist. The evaluation data must include a description of the implications of the hearing loss for the student's hearing in a variety of circumstances with or without recommended amplification.

Deaf-Blindness (DB)

A student with deaf-blindness is one who has been determined to meet the criteria as stated in 34 CFR,§300.8(c)(2):

  • Deaf-blindness means concomitant hearing and visual impairments, the combination of which causes such severe communication and other developmental and educational needs that they cannot be accommodated in special education programs solely for children with deafness or children with blindness.

In meeting the criteria stated in 34 CFR, §300.8(c)(2), a student with deaf-blindness is one who, based on the evaluations specified in subsection (c)(3) and (12) of this section:

  • (B) meets the eligibility criteria for a student with a visual impairment and has a suspected hearing loss that cannot be demonstrated conclusively, but a speech/language therapist, a certified speech and language therapist, or a licensed speech-language pathologist indicates there is no speech at an age when speech would normally be expected;
  • (C) has documented hearing and visual losses that, if considered individually, may not meet the requirements for a student who is deaf or hard of hearing or for visual impairment, but the combination of such losses adversely affects the student's educational performance; or
  • (D) has a documented medical diagnosis of a progressive medical condition that will result in concomitant hearing and visual losses that, without special education intervention, will adversely affect the student's educational performance.

Emotional Disturbance

A student with an emotional disturbance is one who has been determined to meet the criteria for emotional disturbance as stated in 34 CFR, §300.8(c)(4):

A condition exhibiting one or more of the following characteristics over a long period of time and to a marked degree that adversely affects a child's educational performance:

  • (B) An inability to build or maintain satisfactory interpersonal relationships with peers and teachers.
  • (C) Inappropriate types of behavior or feelings under normal circumstances.
  • (D) A general pervasive mood of unhappiness or depression.
  • (E) A tendency to develop physical symptoms or fears associated with personal or school problems.

The written report of evaluation must include specific recommendations for behavioral supports and interventions.

Intellectual Disability (ID)

A student with an intellectual disability is one who has been determined to meet the criteria for an intellectual disability as stated in 34 CFR, §300.8(c)(6):

  • Intellectual disability means significantly subaverage general intellectual functioning, existing concurrently with deficits in adaptive behavior and manifested during the developmental period, that adversely affects a child’s educational performance.
