Children in the foster care system often face many educational challenges, including having an increased risk of language delays compared to the general population, with an estimated 35%-73% of the foster youth population experiencing language difficulties. Language delays are caused by many factors, but for children in foster care, one major antecedent is child abuse and neglect. Early delays greatly impact long-term outcomes for children, including delays in their reading, writing, and social competence. This article explores possible causes of language delays for youths in foster care, describes the negative impact of language delays, and identifies evidence-based practices for early intervention within the child welfare system and primary and secondary schools, specifically targeting practices for school psychologists, school counselors, school social workers, and speech pathologists.
