Measurement reliability is important in scoring students' tests because it indicates the consistency and reproducibility of a student's ability in a particular area. This is essential in determining a student's actual proficiency and progress over time, as well as making fair and accurate comparisons among students.

Choice B is incorrect because although reliability is a necessary element of validity, the two concepts are distinct and separate.
