As many individuals responding to this proposed change have noted, while testing is useful, its not routinely indicated in many situations.  When standardized testing is warranted, is is almost always administered in a process that includes a battery of tests and one or more hours of clinical interviews.  I cannot imagine a administering any one standardized test as a pre and post measure that could have utility across the range of concerns that bring individuals to see a psychologist.  There is strong evidence suppporting the utility of careful clinical interviewing and testing when needed to clarify certain diagnostic concerns.  I see this proposal as overly simplistic,  expensive, and disruptive to the work of clinical psychologists.
