for example, the SAT scale (within a subject area) runs from 200 to 800, while that of the ACT runs from 1 to 36. There is no substantive reason for this difference; no one would argue that a student who reaches the top score on the SAT knows twenty-two times as much as a student who reaches the maximum score on the ACT. And the ranking of college applicants would not be altered if ACT scoring were switched to match the SAT scale, or the College Board decided to change the SAT scoring to the ACT scale.
