To be useful as predictive and diagnostic selection tools, test must satisfy certain basic requirements:
• Reliability: Test scores should not vary widely under repeated conditions. If a test is administered to the same individual repeatedly, he should get approximately identical score. Reliability is the confidence that an indicator will measure the same thing every time.
• Validity: Validity is the extent to which an instrument measures what it intends to measure. In a typing test validity measures a typist’s speed and accuracy. To determine whether it really measures the speed and accuracy of a typist is to demonstrate its validity. The question if determining the validity of a selection test, thus, has a lot to do with later performance on the job.
• Qualified People: Test require a high level of professional skills in their administration and interpretation. Professional technicians are needed for skilled judgmental interpretations of test scores.
• Preparation: A test should be well prepared. It should be easy to understand and simple to administer.
• Suitability: a test must fit the nature of the group on which it is applied. A written test comprising difficult words would be fruitless when it is administered on less educated workers.
• Usefulness: Exclusive reliance on any single test should be avoided, since the results in such a case are likely to be criticized. To be useful, it is always better to use a battery of test.
• Standardization: Norms for finalising test scores should be established. There must be prescribed methods and procedures for administering the test and for scoring or interpreting it.
