When should you discontinue the PS?

The correct response indicates that you should discontinue the Processing Speed (PS) subtest after receiving three scores of 0. This criterion is based on established guidelines that assess a child's ability to respond effectively to the test items. When a child demonstrates a consistent inability to score above zero on three consecutive items, it suggests that they may not have the necessary skills or understanding to continue, making further testing unproductive.

This approach not only helps to ensure that the testing process respects the child's capabilities and comfort but also helps in the efficient use of time. If a child is scoring zero, it is an indication that they may be experiencing difficulty or difficulty in understanding the task demands. Continuing to administer the subtest would not provide valid or useful data regarding the child's true processing speed abilities.

Discontinuing the test after three scores of 0 allows the examiner to focus on other areas of assessment or tests, ensuring that the overall evaluation remains comprehensive while being sensitive to the child's individual performance and needs.
