For the DS qualifying item, the minimum number to count correctly is?

In the context of the WISC-V, when assessing the Digit Span subtest, which is often used to evaluate working memory, the minimum number of correctly recalled digits to qualify for further scoring is indeed three. The Digit Span task involves the participant listening to a sequence of numbers and then repeating them back in the same order for Digit Span Forward, or in reverse for Digit Span Backward.

The rationale behind needing a minimum of three correct responses lies in the psychometric properties of the test, ensuring that the assessment reflects a reliable measure of working memory capacity. A span of fewer than three answers could indicate that the test is not capturing the cognitive abilities intended to be measured, as the task becomes too simplistic and may not challenge the child appropriately. By requiring a minimum of three to count correctly, the assessment can better distinguish between different levels of working memory ability.

Understanding this criterion helps in evaluating a child's performance comprehensively and helps in making informed decisions based on their cognitive abilities.
