The Miller Analogies Test (MAT) is a standardized test used both for graduate school admissions in the United States and entrance to high I.Q. societies. Created and still published by Harcourt Assessment (now a division of Pearson Education), the MAT consists of 120 questions in 60 minutes (formerly 100 questions in 50 minutes). Unlike other graduate school admissions exams such as the GRE, the Miller Analogies Test is verbal or computer based.
