The WJ IV Tests of Oral Language provide contemporary critical measures of oral language abilities for diagnostic decision-making utilising patterns of strengths and weaknesses (PSW) and providing a measure of Cognitive-Academic Language Proficiency (CALP). 

  • Innovative design makes the Tests of Oral Language an important diagnostic supplement to the Tests of Cognitive Abilities and the Tests of Achievement. 
  • Allows for the evaluation of strengths and weaknesses among oral language abilities of a complete assessment of specific learning disabilities, including dyslexia 
  • The new Segmentation test provides essential information about phonological processing. 
  • Increases diagnostic sensitivity with measures of phonetic coding and speed of lexical access 
  • Yields a measure of Cognitive-Academic Language Proficiency (CALP) which is often more useful in academic settings than measures of Basic Interpersonal Communication skills (BICS) 
  • Provides a unique comparison of oral language comprehension—in English, for comparison to levels of academic achievement 
  • Compares achievement levels to oral language ability for a complete picture of the child’s skills
