This paper introduced a useful parent report instrument which Bates and her colleagues have developed over the past decade. Parents will be able to provide a valuable overall evaluation of children's language, when carefully assessed.
Based on the Language Inventory by Fenson, Thal, Reilly, Vella & Guisti (1988), the Japanese versions of Early Language Inventory : Infant and Early Language Inventory : Toddler, were constructed. More consideration and revision will be needed for the checklists of vocabulary and combinatorial language in the Japanese version.
