The University of Missouri-Columbia (Mizzou) doesn't have a specific ACT score requirement that guarantees admission. Admission is holistic, meaning they consider your entire application, not just your test scores. While they don't publish a minimum ACT score, successful applicants generally have scores in the range of
21-27, but a higher score significantly improves your chances, especially for competitive programs.
It's crucial to check Mizzou's official website for the most up-to-date information and to understand that your chances of admission depend on many factors beyond just your ACT score, including your GPA, high school coursework, extracurricular activities, essays, and letters of recommendation.
