Performance based assessments are typically viewed as providing more valid data than traditional examinations because they focus more directly on the tasks or skills of practice. Reliability refers to the extent to which an assessment method or instrument measures consistently the performance of the student.
Reliability is the degree to which an assessment tool produces stable and consistent results. The obtained correlation coefficient would indicate the stability of the scores.
