Article History: Purpose: In grading, one of the most common errors is made in combining two or more different test scores. This study aimed to investigate the agreement of grades calculated by weighting raw scores and standard scores. Research Methods: In this simulation study, data were simulated for midterm and final measurements. Nine conditions [3 (class level: poor, average, good) x 3 (standard deviation (SD) difference (0, 10, and 20 units)] were considered. The sample size for each measurement was taken as 60 and the replication number set to 100.
