• Quantitative Evolution: The quantitative evaluation refers to numerical assessment of attributes of an individual.
• Standardized Procedure: Standardization implies uniformity of procedure in administering and scoring the test.
• Behavior sampling: Neither the subject nor the examiner has sufficient time for truly comprehensive testing, even when the test is targeted to a well- defined and finite behavior domain. Thus, practical constraints dictate that a test is only a sample of behavior.
• Score of categories: Every test furnishes one or more scores or provides evidence that a person belong to one category and not another. Psychological testing sums up performance in numbers or classifications.
• Norm or Standards: An examinee’s test score is usually interpreted by comparing it with the score obtained by others on the same test. To this purpose, test developers typically provide norms-a summary of test results for a large and representative group of subject.
• Predication of Non-test Behavior: The tests have more interest in the non-test behaviors predicated by the test than in the responses.
• Objectivity: The administration, scoring and interpretation of score are objective insofar as they are independent of the subjective judgment of the particular examiner.
• Reliability: Reliability refers to the attribute of consistency in measurement. Test reliability is the consistency of scores obtained by the same persons when retested with the identical test or with an equivalent form of the test.
• Validity: The validity of a test concerns what the test measures and how well it does so.
• Applicability: Applicability of a test refers to it will not expensive, not time consuming, scoring in short time, easily movable and applicable.
