If a substitution is not made, will the scoring assistant prorate the score?

Frequently Asked Question:

If a substitution is not made, will the scoring assistant will prorate the score?

Resolution:

Substitution is the preferable method when one of the subtests of the WISC-IV assessment is invalid. However, if a substitution selection is not made, then a message will appear alerting you to the fact that if a substitution is not made, the scoring assistant will prorate the score.

1. Verbal Comprehension Composite: Substitute Information or Word Reasoning for Similarities, Vocabulary, or Comprehension
2. Perceptual Reasoning Composite: Substitute Picture Completion for Matrix Reasoning, Block Design, or Picture Concepts.
3. Working Memory Composite: Substitute Arithmetic for Letter Number Sequencing or Digit Span.
4. Processing Speed Composite: Substitute Symbol Search or Coding for Cancellation.

If a supplemental subtest score was not provided, the corresponding checkbox and drop-down boxes will be disabled. Thus, the 'Not Available' text will be displayed in the substitution subtest drop-down list box.
