What is the conversion from ACT to SAT, and vice versa?
For one example of a score conversion table, please see this chart. Score conversion tables vary, but not by too much. Click here for one from the UC system (scroll down for the conversion to a “UC score.”). Please keep in mind that these “score concordance tables,” as they are called, are simply comparisons of student percentiles from each test. These are not exact comparisons, because not every student takes both the SAT and the ACT.
