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.
Interpreting an IQ Score. According to Palmer's 2006 publication, a child who scores between 90 and 109 on an IQ test is classified as having an average level of intelligence. Students who score below 70 on an IQ test are designated with a borderline intellectual disability or some form of mental delay.
