About some approaches for converting test scores into grades

Subject of research: Computer testing for evaluating the results of mastering an academic discipline in a higher educational institution. Purpose of research: The problem of subjectivity in determining threshold values when translating test scores (from 0 to 100) into the usual five-point scale of marks. Methods and objects of research: It is proposed to use methods of mathematical statistics for processing test results data in determining the threshold values of test scores. Main results of research: The approaches currently used in practice are considered and evaluated. Variants of alternative approaches to solving the problem are proposed.
