  • Two tests that have the same items but measure different constructs
  • Two tests that have different items but measure the same construct in the same way (correct)

  • Two tests that have different items but measure different constructs

    • What is tau-equivalence in the context of parallel tests?

  • The true scores associated with each test represent different constructs, but each test is measuring the same thing in the same way
