2. Williams, Arthur (2001). Psychometric concerns in neuropsychological testing. Neuro Rehabilitation 16. Attempts to describe measurement and norming problems that both exist and are common among neuropsychological tests Shows the need for further development in neuropsychological testing.

3. Problems with Batteries Few batteries to show the ability of the test to distinguish between two or more diagnostic groups of concern Standardize flexible and fixed battery tests

4. Flexible Battery Problem Scores on flexible battery tests differentiate No group for comparison can exist No bell shaped curve Tests lack accuracy

5. Reliability Minimum reliability is 0.80 Many do not give reliability Collecting new evidence is necessary

6. Problem Comparing Scores Comparing scores to means and standard deviations of “normal samples” Different scores from tests No normative sample

7. Critical Review Tests should be used with extreme caution Further research is needed
