Test and Measurement

The term psychological test brings to mind a number of conflicting images. On the 1 hand the term might make one think of the type of test so often described in television, movies and popular literature, wherein a patient answers questions like, "How long have you hated your mother?" and in doing so reveals hidden facts of his or her personality to clinician. On the other hand the psychological test might refer to a long series of multiple-choice questions such as those answered by hundreds of high school students taking college entrance examinations. Another type of psychological test is the self-scored type publish in Reader's Digest which purports to tell you whether your marriage is on the rocks, whether you are as anxious as the next fellow, or whether you should change your job or your life-style.
The 1st question is , "Why is psychological testing important?".
There are several possible answers to this question, but we believe that the best answer lies in the simple statement.

Tests are used to make important decisions about individuals.

College admissions officers consult test score before deciding to admit or reject applicant.
Clinical psychologists use a variety of objective and projective tests in the process of choosing a course of treatment for individual clients.
The military uses test scores as aids in deciding which jobs an individual soldier might be qualified to filled.
Tests are used in the world of work, both in personnel selection and in professional certification and licensure.
Psychological tests are used to measure a wide variety of attributes-intelligence, motivation, mastery of seventh-grade mathematics, vocational preferences, spatial ability, anxiety, form perception and countless other.

In reality no method guarantees complete accuracy. Although psychological tests are far from perfect, they represents the best, fairest and most accurate technology available for making many important decisions about individuals. Psychological testing is not only important and highly controversial , it is a highly specialized and somewhat technical enterprise.
