The Miller Analogies Test (MAT) is a standardized test used primarily for graduate school admissions in the United States. 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.
