Standard scores are preferred because they provide a more accurate reflection of differences among students. Percentile ranks only show a student's relative position compared to others and do not provide information about the actual score. Standard scores, on the other hand, convert raw scores to a common metric and provide information about the distance between a student's score and the mean of the population.
