This memorandum provides guidance on issues raised regarding the Head Start Performance Standards for Children with Disabilities, federal regulations to ensure that young children with disabilities receive appropriate Head Start educational and related services. Extensive answers are provided to questions concerning: (1) financial responsibility for paying for needed special education and related services for children with disabilities; (2) the requirement that Head Start programs enroll eligible children without regard to the severity of the disability; (3) eligibility in cases where the formal evaluation concludes that the child does not meet the state's disability criteria but does meet Head Start disability criteria; (4) requirements concerning the training and qualifications of Head Start program staff; (5) the local education agency's responsibility to develop the Individualized Education Program; (6) the lack of relationship between the 10 percent over-income limitation and the 10 percent minimum enrollment of children with disabilities; (7) non-applicability of standards for services for infants and toddlers; (8) timelines for screening and evaluations; and (9) school-system established age cutoff dates for eligibility.
