This statistic says that when taking the test, 95% of the time the results will be in the spectrum given. The 95% Confidence Interval is a statistical way of saying the results sometimes might not be accurate. If the percentile is 60, for example, he did better than 60% of others who were tested using the WAIS. This score will show how the examinee did on the test compared to other people his age. The average percentile is 50%, so a percentile of 50 would equate to an IQ of 100. The highest possible score here is 99.9%. The next column is usually the Percentile Ranking. On the other end of the spectrum, from 80 to 89 is considered Low Average, 70 to 79 is Borderline, and 69 and below are Extremely Low. Score from 110 to 119 are considered High Average, from 120 to 129 are Superior, and from 130 and up are Very Superior. Anything from 90 to 109 is considered Average. The Composite Score is the IQ, where the average score is 100. The first step in analyzing scores is to look at the WAIS Composite Scores for the broadest topics. Finally, Processing Speed is how quickly the examinee can process routine information such as reading and reasoning. Working Memory is the examinee’s ability to sustain attention and concentration. Perceptual Reasoning measures nonverbal learning, including visual perception and coordination. The Verbal Comprehension score measures verbal reasoning and concept formation. Tests are further broken down into Verbal Comprehension, Perceptual Reasoning, Working Memory, Processing Speed, and Full Scale IQ. The examinee is given three basic scores: Verbal IQ, Performance (nonverbal) IQ, and Full Scale IQ. The test results also provide the raw and scaled score for each test, as well as a percentile rank. The standard deviation for IQ results is 15, which means that about 68% of scores fall between 85 and 115. The average score for all tests and subtests is 100 thus, a score of over 100 is above average and below 100 is below average. It includes both verbal and nonverbal components.

The Wechsler Adult Intelligence Scale-IV (WAIS-IV) is an IQ test that is given by psychologists and measures global intellectual functioning.
