Early Childhood Special Education



Developmental Delay Definition

Child with a disability for children aged three to age nine (or any subset of that age range, including ages three through five), may…include a child—

(1) Who is experiencing developmental delays as defined by the State and as measured by appropriate diagnostic instruments and procedures in one or more of the following areas: Physical development, cognitive development, communication development, social or emotional development, or adaptive development; and

(2) Who, by reason thereof, needs special education and related services. [34 CFR §300.8(b)]


Key Eligibility Indicators

A preschool child three to Kindergarten school age, who is, turning five by September 2, must be determined to be eligible as a child with a developmental delay requiring special education and related services if one or more of the two eligibility criteria below are met:

  • Functioning one and a half standard deviations below the mean in two domains or two standard deviations below the mean in one domain; or
  • In extraordinary cases when a standardized score cannot be determined, a child may be determined to have a disability based on functionality and the informed opinion of the group with documentation of the rationale for the inability to obtain a standardized score The evaluation results identifying the areas of the developmental delay should be documented on the MEEGS (OSDE Form 5), along with present levels of performance in age appropriate activities and consideration of the educational needs resulting from the disability.

For children, Kindergarten school age (turning five by September 2) to age nine, criteria for delay in developmental domains or indicators for specific disability categories may be used to determine eligibility through the comprehensive evaluation process for developmental delay. Criteria for specific disability categories (e.g., autism, speech language impairment, other health impairment) may be used to determine developmental delay eligibility for children in this age range.

If the LEA has chosen to use the term "developmental delay,"the eligibility category on the MEEGS form should be "developmental delay" (except for the categories of deaf-blindness, hearing impairment including deafness, and visual impairment including blindness), even though the child qualifies for special education and related services by meeting the criteria for a specific disability category. For example, a child may be determined eligible under developmental delay by meeting the criteria for specific learning disability (i.e., utilizing the components of a comprehensive evaluation for specific learning disabilities).

Components of a Comprehensive Evaluation

  • Adaptive Development
  • Cognitive Development
  • Communication
  • Social or Emotional Development
  • Physical Development

The evaluation procedures must identify all of the child’s special education and related services needs.

When determining eligibility for a preschool child three to Kindergarten school age, who is turning five before September 2, the team must document levels of developmental functioning through an evaluation procedure in all five domains and present levels of performance. At least two independent procedures must be used to document the current levels of performance. One procedure must be norm-referenced. Information sources, such as medical records, social services records, parent and provider interviews, anecdotal information, and child observation records must be documented as information considered in the evaluation process to assist in determining eligibility, educational needs, measurable annual goals, services, and placement in the least restrictive environment (LRE).

When it is not possible to obtain valid results from standardized/norm-referenced assessments due to the nature or severity of the delay, at least two independent sources of diagnostic information must be utilized to substantiate the delay. Information from instruments, along with existing data and functional assessments, may be used for documentation of present levels. Depending on the individual needs of the child, AT and other special factors maybe additional considerations for evaluation.
