The psychometric status of child language assessment tools in South Africa’s official languages

Abstract

Despite advancements in recognising the importance of early child language development and linguistic diversity in South Africa, culturally and linguistically appropriate assessment tools remain unevenly distributed across the official languages, posing considerable challenges for researchers and speech-language therapists. This study critically reviews the psychometric status of child language assessment tools in South Africa’s official languages. The current state of tool development is analysed, evaluating language assessment tools available for clinical and research purposes in each language. Tools that assess speech sounds, phonological processing and (pre)literacy skills were excluded, as were untraceable tools reported in previous publications, and tools that do not assess language only but form part of larger developmental assessments. Considering each language version of a tool, 37 traceable language assessment tools (at least 1 per official language), in various states of readiness, are available for use with South Africans aged 0–12 years. Out of these 37 tools, 5 tools, with collectively 7 language versions, have been validated and the statistical results of the validation study published: 4 for isiZulu, 2 for English and 1 for Siswati. Despite advances in tool development, there is still a severe lack of validated standardised child language measurement tools in all official languages of South Africa.
Contribution: This is the most recent critical review of the psychometric properties of tools developed for assessing South African children’s language skills, and it highlights that past and current efforts in tool development are still insufficient.
