The minimum scores for ACT are 18 for Reading Section, 17 for English Section, and 19 for Math Section. The SAT is usually taken in the early fall (October or November) of the senior year. A number of juniors take the test in the late spring (May or June) and take it again in the senior year.
An IQ score of 115 means performance one standard deviation above the median, a score of 85 performance one standard deviation below the median, and so on. Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number by either procedure.
Their IQ scores ranged from 77 to 135, with an average score of 112. Four years later, the same group took another IQ test. While the average score of 113 was only one point greater than the previous test, the range of scores was quite different: 87 to 143.our years later, the same group took another IQ test.
