An investigation into differences in early childhood developmentVariability in Early Communicative Development demonstrates that the "modal child" does not, in fact, exist. Interviews with parents of over 1,800 children reveals both typical and exceptional communication development between the ages of eight and 30 months, providing unusually specific detail on the variability of individual lexical, gestural, and grammatical skills. Discussion of the Macarthur Communicative Development Inventories delves into the inventory's reliability, validity, and interrelations, before moving into an examination of the stability of differences and individual contributing factors.

Professionals can learn a great deal about young children's emerging language and communication skills by consulting the ones who know the children best: their parents or caregivers. CDIs At A Glance - Age range covered: 8-30 months (may also be used with older children who have developmental delays); Areas screened: Language and communication skills; Approximate time for the CDI: Each form generally takes 20-40 minutes to complete and 10-15 minutes to score; Who completes it: Parents or caregivers; professionals score; and Validity and reliability: Numerous studies document the reliability and the validity of the instruments. The CDIs were normed on approximately 1,800 children in three locations, and the Inventaries were normed on more than 2,000 children. Now, with the CDIs professionals can tap into parents' invaluable day-to-day knowledge - and respond to legislation that requires parental input in child evaluations. Top language researchers developed these standardized, parent-completed report designing the forms to focus on current behaviors and salient emergent behaviors that parents can recognize and track. A ""words and gestures"" form. ""The CDI: Words and Gestures"" is for use with children ages 8-16 months, the first part prompts parents to document the child's understanding of hundreds of early vocabulary items separated into semantic categories such as animal names, household items, and action words.
