SA-CDI
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 CLDN has completed the validation of the SA-CDIs and is currently in the norming phase.

Language Assessments
The CLDN has been involved in the development of two language assessments: The Diagnostic Evaluation of Language Variation and The LITMUS Cross-Linguistic Lexical Tasks. The Diagnostic Evaluation of Language Variation (DELV) is a picture-based language assessment designed to distinguish between a language difference and a language disorder in four- to nine-year-old children. It was originally developed for child speakers of different varieties of American English, but has been adapted for South African English and translated and adapted for Afrikaans. The LITMUS Cross-Linguistic Lexical Tasks (CLTs) are standardized, picture-based vocabulary assessments developed within the Language Impairment Testing in Multilingual Settings (LITMUS) project to evaluate lexical knowledge of monolingual and multilingual children.

REACT
Reducing the Educational Achievement Gap through Community-led Technology (REACT) is a project that seeks to bridge the socio-economic and linguistic divide in South African communities.
Initiated by the Child Language Development Node of the South African Centre for Digital Language Resources (SADiLaR), the REACT project aims to use community collaboration and human language technologies (HLTs) to measure and strengthen early language development. It is also supported by a Spencer Foundation Vision Grant.
