An intelligence test is also referred to as a cognitive assessment and is often administered to obtain more information about a student’s intellectual strengths and weaknesses and her overall cognitive potential. The test gives general information about a student’s abilities compared to others his age in several areas. The tests are intended to be a predictor of how well and in what ways a child will learn new information. However, other factors must ALWAYS be considered. A high IQ does not guarantee success, just as a low IQ does not guarantee failure.
Most intelligence tests consist of a Full Scale score, processing scales, and several subtests or tasks. The Full Scale score or IQ score takes into consideration all of the subtests administered and portrays a student’s overall cognitive ability. The processing scales will be made up of a few subtests that measure the way a student processes information. Each subtest is a unique task that measures a different way of learning or processing information. Each cognitive assessment is different and is made up of different tasks. However, they typically measure verbal ability (understanding and expressing verbal knowledge) and nonverbal ability (reasoning ability without the use of words and visual-motor ability). Memory, processing speed, and spatial abilities are often measured as well.
IQ tests were given to thousands of children to help standardize the test and give percentile scores. When your child took the test, her performance was compared to all the other children given the assessment in the standardization and a percentile score was given. All other scores (Standard Scores, T Scores, and Scaled Scores) are formulated based on the percentile. Typically, scores are presented in Standard Scores, which is best understood in ranges. The Average range is typically 90-110. High Average range 111-120, Superior 121 and above. Scores in the 80-89 range are Low Average, 70-79 are Borderline, and below 70 are Extremely Low.
