Uncertainty in Grade Evaluation Caused by Different Factors

Abstract

This study discusses the uncertainty in grade evaluation. Two courses in the first-grade students were chosen for evaluation. The uncertainty in the average score in the examinations was 7 points even under the same condition but taught by different lectures. In the condition where the syllabus and evaluation criteria were identical, the uncertainty caused by combined factors was found to be 15 points. Successive faculty development tends to make the score deviation converged in two different groups.
