The SA Communicative Development Inventories (SA-CDIs) are a set of questionnaires for each official South African language that parents complete to tell us about their child's language and communication.
The SA-CDI project will establish:
- the first comprehensive overview of South African children's first stages in language development
- the first word-learning norms for children aged 8 to 30 months across the whole of South Africa
- a free-to-use, anonymised online child language base, in collaboration with SADiLaR
- a quick, easy and inexpensive checklist that can be used by professionals to assess children's language
