What are Case 25th-75th percentile SAT scores?

There's no standard definition of "Case 25th-75th percentile SAT scores." The 25th-75th percentile range refers to the middle 50% of scores for a *specific group* of test-takers. That group could be:

* All test-takers: This would show the middle 50% of scores for everyone who took the SAT in a given year. These are widely published by the College Board.

* Applicants to a specific college: A college might report the SAT scores of its admitted students, showing the range where the middle 50% of *accepted* students' scores fell. This is far more relevant to an individual applying to that college.

* Students in a particular high school: A school might track the SAT scores of its graduating class.

* Students in a specific program or major: A university program might report the range of SAT scores for its students.

To find the 25th-75th percentile range you need to specify the group whose scores you're interested in. You won't find a single "Case" range.
