A personality test is a sample behavior acquired under standardized circumstances with scoring rules to obtain information from the behavior sample. Special traits are measured or outcomes predicted using a subject's behavior. To generate accurate information about a subject's behavior, the test has to be administered under standardized conditions and there should be a well defined approach to describe the subject's behavior in response to the test. A good test must also be reliable and valid (Murphy & Davidshofer, 1998). The purpose of testing is to evaluate behavior, mental abilities and other personal characteristics to make judgments, predictions, and decisions about people (Aiken, 1997). Tests are used for selections in business (job suitability), in schools (admission into special classes), for placements and to indicate competency. Clinicians use tests to determine a patient's hidden characteristics, pinpoint areas of pathology or adjustment problems and to plan treatments. Tests can also be used to evaluate outcomes like method effectiveness (Friedenberg, 1995). A good test is designed cautiously and evaluated so that it produces accurate, useful
Research found that weighting is more reliable than conventional scoring (Serlin & Kaiser, 1978). All personality tests (MMPI, TAT, etc. It shows the individual's distance from the mean in terms of standard deviation. As the person administering a standardized test is rarely the one who constructed it, he should study the test manual cautiously to be familiar with the directions for administration and the content of the test before trying to conduct it. Criterion-related validity refers to validation procedures in which test scores of a group of people are compared with ratings or other behavioral measurements. Although it is the most satisfactory type of score, there are technical objections (large sample size needed) (Anastasi & Urbina, 1997). An individual who solved 10 problems on a test provides little information how much of a trait he has. A raw score on any personality test is pointless due to lack of further interpretative data. After the test, test materials should be collected and secured. An age norm is the median score on a test obtained by persons of given chronological age while a grade norm is the median score earned by persons of given grade. Test directions which inform examinees of the purpose of the test and how to indicate their answers should be read slowly and clearly. Studies have proved that online tests can have acceptable psychometric properties. Practice produces different amounts of improvements in retest scores of different individuals. Criterion is contaminated by the particular method of determining the criterion scores.
