The kind of reliability evidence obtained by having individuals take two different test forms that assess the same content is called: Options: (a) Split-half reliability (b) Test-retest reliability (c) Internal consistency (d) Alternate forms reliability ✅ Correct Option: (d) Alternate forms reliability Explanation (200+ words): Alternate forms reliability refers to the consistency of scores obtained when the same individuals take two different versions of a test that measure the same content. These test forms are designed to be equivalent in difficulty, length, and content coverage. The purpose is to ensure that variations in scores are due to true differences in ability rather than differences in test forms. This type of reliability is particularly useful when repeated testing is required, such as in large-scale assessments or competitive exams, to avoid practice effects. If students receive similar scores on both forms, the test is considered reliable. Alternate forms reliability helps test developers ensure fairness and consistency across different test administrations. However, developing truly equivalent forms is time-consuming and costly. Despite this, it remains an important method for evaluating test reliability. 10 Related PPSC Facts: Also called parallel forms reliability. Requires two equivalent test forms. Minimizes practice effects. Used in standardized testing. More rigorous than split-half reliability. Ensures fairness across test versions. Correlation coefficient measures reliability. High cost of test development. Common in entrance examinations. Measures consistency, not accuracy.
