A scaled score is the result of some transformation(s) applied to the raw score, such as in relative grading. The purpose of scaled scores is to report scores for all examinees on a consistent scale. Suppose that a test has two forms, and one is more difficult than the other. It has been determined by equating that a score of 65% on form 1 is ...
A total score for the SAT is calculated by adding the two section scores, resulting in total scores that range from 400 to 1600. In addition to the two section scores, three "test" scores on a scale of 10 to 40 are reported, one for each of Reading, Writing and Language, and Math, with increment of 1 for Reading / Writing and Language, and 0.5 ...
In order to make cross-year score comparisons possible, in April 1941 the SAT verbal section was scaled to a mean of 500, and a standard deviation of 100, and the June 1941 SAT verbal section was equated (linked) to the April 1941 test. All SAT verbal sections after 1941 were equated to previous tests so that the same scores on different SATs ...
Comparison of the various grading methods in a normal distribution, including: standard deviations, cumulative percentages, percentile equivalents, z-scores, T-scores. In statistics, the standard score is the number of standard deviations by which the value of a raw score (i.e., an observed value or data point) is above or below the mean value of what is being observed or measured.
In item response theory, equating [2] is the process of placing scores from two or more parallel test forms onto a common score scale. The result is that scores from two different test forms can be compared directly, or treated as though they came from the same test form. When the tests are not parallel, the general process is called linking.
Scoring is based on a three-step process in which a student’s raw score is scaled based on the test version and then compared to the results of the test scores of normal students in the higher-level grade.

The scaled score was the only score reported to either students or colleges, and ranged from 200 to 800, with 800 being the best possible score. The standard deviation between test scores in 2006 was 102. [2] Less than one percent of the 2006 College-Bound Seniors taking the test received a perfect score of 800. None got a score lower than 260.
