* The Centre of Research Excellence in Child Language has developed a language testing app – called the Short-Form Language Measure – composed of NPVT, CNRep and the Recalling Sentences subtest from CELF-4.  The app has been produced subject to third party licences and any interest in using this app must be directed to the CRE-CL (please contact Penny Levickis).  Employees must not share this app without the CRE-CL being aware of, and approving, such uses.  Please note: VicCHILD used the complete CELF-4 measure.
