A good example of this was when Mississippi test takers routinely outscored those in New York taking the test. There were two reasons. The first was that New York required all students to take the SAT while in Mississippi only students interested in attending college took the entrance exams. The other factor was that the ACT was much more commonly used by admissions offices in Mississippi and surrounding states. So out of college bound students, the SAT typically was only taken by a subset planning on attending schools further away, which were much more likely to be Ivy League or other types of schools that attract students much more broadly than the average state school.
