How many points does the last backward trial score for LDSb if successful?

The correct scoring for the last backward trial in the Letter-Number Sequencing subtest of the WISC-V is indeed 1 point for a successful trial. In this subtest, children are presented with a sequence of letters and numbers to recall in a specific order: first the letters, then the numbers, backward. Scoring is based on the child's successful completion of these tasks, with each sequence having defined scoring criteria.

A successful response on the last backward trial indicates that the child has demonstrated the ability to process and organize information in reverse order, which reflects working memory capacity and cognitive flexibility. Thus, scoring 1 point for the final successful backward trial is consistent with the established guidelines for this specific task within the assessment framework. Understanding this scoring helps clarify how to evaluate a child's cognitive performance on the WISC-V.
