This chapter from a North Dakota guide for early childhood special education personnel focuses on the evaluation and assessment of young children with special needs. Following an introduction, which summarizes requirements under Part H of the Individuals with Disabilities Education Act, overviews of infant development and early childhood special education programs in North Dakota and the application of federal law are provided. A section on identification of young children with disabilities discusses the Child Find program, screening, evaluation for eligibility, assessment for program planning, timelines, and team process. Next, the evaluation/assessment planning process is outlined, including obtaining background information and developing the child profile, facilitating family involvement, and formulating an evaluation/assessment plan. Conducting the actual evaluation is discussed next and includes arena evaluation, play-based evaluation, and using parents and caregivers as a source of information. The final section is on report writing. Subsections explain the Infant Development Report, the Early Childhood Special Education Integrated Written Assessment Report, and the dissemination of information. Appendices include: strategies for professionals working with families from various cultural and/or linguistic groups; questions for professionals to ask when conducting a culturally sensitive screening and assessment; selected evaluation and assessment instruments for early intervention; types of test reliability and validity; and arena evaluation.
