A standard score is derived by converting a raw score (the score a student earns on a test) into a score that is standardized, meaning it allows for comparison across different tests and populations. Standard scores are typically expressed in terms of standard deviation units from the mean. This makes it possible to compare scores on different tests or within different groups, even when the mean and standard deviation of the scores are different. Therefore, option C is the correct answer as it states that the standard score is derived by determining how far from average the student's raw score is in terms of standard deviation units.
