What is the next step if a child messes up on trial 1 of items 1-3 on BD?

If a child messes up on trial 1 of items 1-3 on the Block Design (BD) subtest of the WISC-V, the appropriate next step is to proceed to trial 2. This is based on the testing protocol which outlines that if the child does not achieve the required score on the first trial, it is essential to give them a second opportunity to demonstrate their abilities on that particular task.

Trial 2 is designed to provide a chance for the child to correct mistakes and possibly perform better. This allows for a more accurate assessment of their capabilities, as some children may need a little more guidance or may perform differently when given another chance. The first trial serves as a baseline, and the second trial is aimed at revisiting the task with the hope that the child can improve their performance.

Starting from the beginning or skipping to item 4 would not be appropriate actions because it would either disregard the child's potential learning curve and ability to improve, or it would move past the current assessment area without giving the child a fair chance to demonstrate their skills on the Block Design task. Continuing with trial 1 is not a viable option either because the focus should be on allowing the child to attempt trial 2 after an initial failure.
