Miller Analogies Test
The Miller Analogies Test 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, the MAT consists of 120 questions in 60 minutes. Unlike other graduate school admissions exams such as the GRE, the Miller Analogies Test is verbal or computer based.
Content and use
The test aims to measure an individual's logical and analytical reasoning through the use of partial analogies. A sample test question might beBach : Composing :: Monet :
- a. painting
- b. composing
- c. writing
- d. orating
Unlike analogies found on past editions of the GRE and the SAT, the MAT's analogies demand a broad knowledge of Western culture, testing subjects such as science, music, literature, philosophy, mathematics, art, and history. Thus, exemplary success on the MAT requires more than a nuanced and cultivated vocabulary.
Format and scoring
In the fall of 2004, the exam became computerized; the MAT is now solely a computer-based test.Out of the 120 questions, only 100 count in the test-taker's score. The remaining 20 questions are experimental. There is no way for test-takers to identify any of the 20 experimental questions on a given test form, as the two types of questions are intermingled.
Tests taken before October 2004 were scored simply by the number of questions the test-taker answered correctly, with a range from 0-100. Scores using this metric have historically been known as "raw" scores.
Tests taken in October 2004 or later have a score range from 200 to 600. The median score is 400, with a standard deviation of 25 points. These scores, based on a normal curve, are known as "scaled" scores. Because of their grounding in this model, scaled MAT scores of 500-600 are extremely rare, as they would be more than four standard deviations above the norm of 400.
Percentile ranks are also provided along with the official score report. Test-takers receive an overall percentile rank as well as a percentile rank within their intended graduate school discipline.
The Miller Analogies Test is accepted by Mensa, the Triple Nine Society, and the Prometheus Society for its admission requirements. For tests administered prior to October 2004, a raw score of 66 is required for MENSA qualification. For tests administered during and after October 2004, MENSA requires a score in the 95th percentile for admission. The Triple Nine Society requires at least a raw score of 85 on the "old" MAT, and at least 472 on the modern one. The Prometheus Society requires at least a raw score of 98 on the "old" MAT, and at least 500 on the modern one.
Validity
Kuncel and colleagues investigated the predictive validity of the MAT in both academic and occupational settings. Their meta-analytic study indicated that the MAT is a valid predictor in both domains and that it measures the same abilities as other cognitive ability instruments.
