Welcome to UK-CDI

Transforming our understanding of language and communication development in children

The UK Communicative Development Inventory (UK-CDI) is a questionnaire that parents complete to tell us about their child’s language and communication. The UK-CDI will establish:

the first comprehensive overview of UK children’s first stages in language development

the first word learning norms for children aged 8 to 18 months across the whole of the UK (preliminary norms already available for download)

a free-for-all, anonymised online child language base

a quick, easy and inexpensive checklist that can be used by professionals to assess children’s language (first version of the checklist already available for download)

This is collaborative research between the Universities of Lancaster, Liverpool and Lincoln, funded by the Economic and Social Research Council (ESRC). The links below provide more detailed information:
