Abstract
This study examined the algorithms for reliability estimate as a test-quality indicator. It was discussed along the methods of estimating reliability such as: Test-retest as measures of stability, Equivalent or Alternative –forms reliability as measures of equivalence and stability, while the measures of internal consistency are Split-half, Kuder-Richardson 20 and 21, Coefficient alpha, Hoyt’s analysis of variance, Scorers (Judge) reliability and Inter-rater reliability. Also, using the reliability coefficient as a Test quality indicator was addressed and variables that affect reliability estimate are itemize as test length, test content, test difficulty, item discrimination, group heterogeneity, student motivation, students testwiseness, time limit and security precautions. Therefore, this paper recommends that, in order to demystify the course at any level of our educational system, specialist in the field of Tests, Measurement and Evaluation should be strictly allowed to handle the course and every professional teachers should be abreast to the procedural ways of estimating reliability of test in the classroom examination as a quality indicator in the teachers’ made test.
