Texas State uses a system where they tell you what ACT score you must have for admission based on what percentile of your high school class you are in rather than being based on a calculation with your GPA like many places. So if you are in the bottom quarter of your class - you have to have a 29 ACT, where if you are in the top 25% of your class your ACT score can be as low as 22, and if you are in the top 10% of your class there is no minimum score for your ACT. I’m not sure what I think about that except it seems that they are trying to put more weight on your actual classroom performance and grades versus test scores.
Here is the chart with all of their guidelines:
