A percentile score is a number that represents how many people within the comparison sample scored higher or lower than yours. Among a large group of respondents, your score is ranked with those of other people of your gender who have completed the SCIT. If your percentile score is 63 for example, your score is higher than approximately 63 percent of the other test takers. Conversely, it also means that approximately 37 percent of the test takers had scores higher than yours.
