In partnership with Brookes Publishing and Professor Larry Fenson, The Hanen Centre is pleased to offer the MacArthur-Bates CDI's.  

The first part of the Words and Gestures form prompts parents to document the child’s understanding of hundreds of early vocabulary items separated into 19 semantic categories such as animal names, household items and action words. Parents mark the words understood or used, and the forms yield separate indexes of words understood and words produced. The second part asks parents to record the communicative and symbolic gestures the child has tried or completed. 

Age applicability: For children 8-18 months.
