wait. let me clarify: i believfe that MA level people can be effective PSYCHOMETRICIANS. they are whollly unqualified to interpret data.
you basically had one semester of testing classes. you then obtained a job administering tests. no license test. someone then allows you to interpret these tests. basically there is no quality assurance for the public.
compare to the minimum of 3-4 semesters of assessment classes, followed by a minimum of a year or supervised service in assessment alone before a doctoral candidate, followed by another full 2000 hr internship which has an assessment requirement, followed by a national test. before we can independently do anything. then wrap in a basic component of assessment into every other class.
feeling qualified has nothing to do with being qualified. kruger has something to say about this:

as for your point that you have done something repeatedly: again this is on the job training. taken in its extreme, we could just allow joe blow GED to read a bunch of psych book, buy a few tests and go at it. we require a very specific route for education because it is necessary to understand what you are doing. can you explain why 65 is an important number on the mmpi? how did that number come to be important? what is the false/true positive rates for these instruments? how is a normal curve obtained from the sample? how are those SS derived?
