This project, within the SADiLaR ICELDA node, is aimed at providing fair and diagnostic language tests for academic purposes in the South African context. It includes two PhD studies under my supervision and the redesign of current academic literacy tests used for placement purposes. Apart from successful completion of the aforementioned studies, the project will also contribute to test data being available on a national platform for future use by other researchers. Tests for use at secondary and higher education levels are available in six of the South African official languages, i.e. also contributing towards the advancing multilingualism.
