Screening, Evaluation and Assessment

Screening, evaluation and assessment are distinct processes with different purposes under the provisions of Part C and Part B. Screening includes activities to identify children who may need further evaluation in order to determine the existence of a delay in development or a particular disability. Evaluation is used to determine the existence of a delay or disability, to identify the child's strengths and needs in all areas of development. Assessment is used to determine the individual child's present level of performance and early intervention or educational needs.

The Early Head Start National Resource Center developed a technical assistance paper that defines best observation practices for proper developmental assessment.


Under Part C, screening is at a state's discretion and is part of Post-Referral Procedures. Screening is conducted using appropriate instruments, administered by trained personnel, by the lead agency or an early intervention program. The purpose of screening is to determine whether an infant or toddler is suspected of having a disability and is, therefore, in need of early intervention services. Screening requires parental notice and consent, must be performed within the 45 day timeline, and, at a parent's request and with consent, the EI program must conduct an initial evaluation of the infant or toddler even if the results of the screening do not identify the child as suspected of having a disability. Under Part B, screening may be conducted as part of child find activities in order to ascertain whether the child should be referred for an evaluation to determine if the child has a disability and is in need of special education and related services.

Trends in the Prevalence of Developmental Disabilities in US Children, 1997-2008: Key Findings

In May 2011, the Centers for Disease Control and Prevention (CDC) and the Health Resources and Services Administration (HRSA) published this study. Key findings of the study were that approximately one in six American children have a developmental disability, an increase of 17% during the past 10 years. The increase is thought to have been caused in large part by shifts in the prevalence of autism and attention deficit hyperactivity disorder (ADHD) and may also be related better diagnostic tools, improved screening for disabilities, increased public awareness, more preterm births and higher parental age.

Assuring Better Child Health and Development (ABCD)

This initiative, funded by the Commonwealth Fund and administered by the National Academy for State Health Policy (NASHP), was designed to enhance healthy child development for low-income children, ages 0-3, and their families, by strengthening primary health care services. The ABCD Screening Academy began in April 2007 and focused on the adoption of structured developmental screening of young children. See The Enduring Influence of the Assuring Better Child Health and Development (ABCD) Initiative (July 2013) for a summary of the results of ABCD.

Their site lists states and their newborn screenings, frequently asked questions and a guide about newborn screening for parents (in both English and Spanish).

Evaluation and Assessment

Part C requires a timely, comprehensive, multidisciplinary evaluation of each child, birth through age two. If the child is determined eligible, a child assessment is conducted. Evaluation and assessment (34 CFR 303.321, page 125) are considered processes that have different purposes under Part C. Evaluation is defined as the "procedures used by appropriate qualified personnel to determine a child's initial and continuing eligibility, consistent with the state definition of infants and toddlers with disabilities. " Assessment is defined as "the ongoing procedures used by qualified personnel to identify the child's unique strengths and needs and the services appropriate to meet those needs and includes the assessment of the child and the assessment of the child's family." A family-directed assessment is conducted to identify the resources, priorities, concerns and the supports, and services necessary to enhance the family's capacity to meet the needs of their child. Qualified personnel must use informed clinical opinion and multiple procedures when conducting evaluations and assessments. While a "child's medical or other records may be used to establish eligibility (if those records indicate that the child's level of functioning in one or more of the developmental areas constitutes a developmental delay or that the child otherwise meets the criteria for an infant or toddler with a disability)", an assessment still must be conducted.

  • 303.322 Determination that a child is not eligible
  • 303.420(a)(1) and (2) Parental consent and ability to decline services

Part B (34 CFR 300.15) defines evaluation as the procedures used in accordance with Sec. 300.304 through 300.311 to determine whether a child has a disability and the nature and extent of the special education and related services that the child needs.Evaluation and assessment are not defined as separate processes.

State of the States Policy Snapshot: State Early Childhood Assessment Policies (2014)

This CEELO brief looks at what child assessment measures are being used in pre-kindergarten and kindergarten classrooms across the states and how child assessment data is being used. It is intended to help states learn from each other as they plan to implement new assessments (e.g. kindergarten entry assessments) and comprehensive early childhood assessment systems. It is based primarily on secondary analysis of data collected in the State of Preschool Yearbook and presents a snapshot of responses from the states to questions about child assessment.

This project produced a compendium of early childhood assessments commonly used to measure domains of development, including language and literacy, cognition, mathematics, social-emotional competency, and approaches to learning. Various types of ongoing observational assessments were also included. A profile of each assessment includes the purpose of the measure, key constructs, administration, and reliability information.
