The OPUS is a new measure of auditory comprehension that evaluates a person's ability to listen to passages read aloud and recall information about them. It also measures memory skills, which are integral to listening comprehension.

Features and benefits

Test structure

  • Assesses comprehension of spoken language in the natural context.
  • Evaluates the ability to integrate and apply knowledge in three structural categories of language:
    • Lexical/symantic: Knowledge and use of words and word combinations.
    • Syntactic: Knowledge and use of grammar.
    • Supralinguistic: Knowledge and use of language in which meaning is not directly available from the surface lexical and syntactic information.
  • Consists of 17 passages divided into six Item Sets. Each Item Set has five passages and up to 44 items.
  • Passages are taken from published works and created to reflect the type of material one is likely to encounter in everyday life.

Technical information
