Miller Analogies Test
The Miller Analogies Test was a standardized test used both for graduate school admissions in the United States and entrance to high I.Q. societies. Created and published by Harcourt Assessment, the MAT consisted of 120 questions in 60 minutes. The test was discontinued in 2023, with the last tests administered on or before November 15, 2023.
Content and use
The test aimed to measure an individual's logical and analytical reasoning through the use of partial analogies. A sample test question might have been:Bach : 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 demanded a broad knowledge of Western culture, testing subjects such as science, music, literature, philosophy, mathematics, art, and history. Thus, exemplary success on the MAT required more than a nuanced and cultivated vocabulary.
Format and scoring
In the fall of 2004, the exam became computerized.Out of the 120 questions, only 100 counted in the test-taker's score. The remaining 20 questions were experimental. There was 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 had a score range from 200 to 600. The median score was 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 were extremely rare, as they would have been more than four standard deviations above the norm of 400.
Percentile ranks were also provided along with the official score report. Test-takers received an overall percentile rank as well as a percentile rank within their intended graduate school discipline.
The Miller Analogies Test used to be accepted by American Mensa, and still is by Intertel, the Triple Nine Society, the International Society for Philosophical Enquiry and the Prometheus Society for its admission requirements. Intertel requires a raw score of 74 on the "old" MAT, or a score at the 99th percentile on the modern one. The ISPE and the Triple Nine Society require 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.
