Question: what act score is needed for illinois state university?
Answer: The 25th percentile ACT score is 21, and the 75th percentile ACT score is 26. In other words, a 21 places you below average, while a 26 will move you up to above average. There's no absolute ACT requirement at Illinois State University, but they really want to see at least a 21 to have a chance at being considered.
