The value of early intervention is well demonstrated; however, less is known about the processes that initial evaluation teams use to evaluate and determine young children's eligibility for early intervention (EI) and preschool special education. The present study surveyed multidisciplinary early childhood providers (N = 1445) who conduct initial evaluations for young children. Quantitative survey data were analyzed using descriptive analyses to describe the location of initial evaluations, tools used, team membership, and approaches to eligibility determination for children with possible delays and disabilities. Evaluation practices varied greatly, but evaluation teams most often included early childhood special educators and speech and language pathologists, school psychologists or other specialists were less frequently involved. Eligibility approaches were also wide-ranging with percentage delay and standard deviation below the mean most often used; several challenges when determining eligibility were also described. Evaluations for EI and preschool special education were compared to look at variations. Statistically significant differences were found when comparing evaluations focused on eligibility for EI or preschool special education. Implications and future directions are explored.
