Capture parents’ knowledge of their child’s emerging language skills
The MacArthur-Bates Communicative Development Inventories (CDIs), and the corresponding Spanish-language Inventarios, provide a systematic way for professionals to use parents as informants regarding their child’s language. They enable professionals to tap into parents’ knowledge about their young children’s communicative development for use in screening and developing a prognosis for children with language delays. It also ensures they are meeting mandates for including parent input in child evaluation procedures.
The goal of the CDIs is to yield reliable information on the course of language development from children’s early signs of comprehension, to their first nonverbal gestural signals, to the expansion of early vocabulary and the beginnings of grammar.
