Measurement in psychology and physics are in no sense different. Physicists can measure when they can find the operations by which they may meet the necessary criteria; psychologists have to do the same. They need not worry about the mysterious differences between the meaning of measurement in the two sciences (Reese, 1943, p. 49). [9]
Psychological testing refers to the administration of psychological tests. [1] Psychological tests are administered or scored by trained evaluators. [1] A person's responses are evaluated according to carefully prescribed guidelines. Scores are thought to reflect individual or group differences in the construct the test purports to measure. [1]
The current MMPI-2 has 567 items, and usually takes between one and two hours to complete depending on reading level. It is designed to require a 4.6 grade (Flesh-Kincaid) reading level. [24] There is an infrequently used abbreviated form of the test that consists of the MMPI-2's first 370 items. [25]
It is a theory of testing based on the relationship between individuals' performances on a test item and the test takers' levels of performance on an overall measure of the ability that item was designed to measure. Several different statistical models are used to represent both item and test taker characteristics. [1]
This test was also not favorable, as it took over 100 hours to administer. However, this influenced Wilhelm Wundt, who had the first psychological laboratory in Germany. His tests were shorter, but used similar techniques. Wundt also measured mental processes and acknowledged the fact that there are individual differences between people.
These multiple levels of review by psychologists and the ongoing analysis of psychometric data ensures that the EPPP is accurate, relevant, valid, and legally defensible. [12] Over the years, the test development strategies used by ASPPB in developing the EPPP have been described many times in the psychological literature.

Classical test theory is an influential theory of test scores in the social sciences. In psychometrics, the theory has been superseded by the more sophisticated models in item response theory (IRT) and generalizability theory (G-theory).
