If a WAIS-5 report has landed in front of you, whether it is your own or a family member’s, the Verbal Comprehension Index is often one of the first scores you will want to make sense of. This guide explains what it measures, how to read the number, and what it does and does not tell you, in plain language.
The Quick Answer
The Verbal Comprehension Index, usually shortened to VCI on a report, is a measure of verbal reasoning: how well a person understands words and ideas, draws on knowledge built up over time, and puts their thinking into language. It is one of five main index scores on the WAIS-5. On its own it describes one slice of thinking, not a person’s overall ability, and no single index decides what a report means.
