Intelligence quotient, or IQ, tests are designed to assess either how intelligent an individual is or his academic abilities and possible learning needs. Scores vary from test to test, as do the types of questions. Students sometimes perform better on one IQ test as opposed to another because of these variables, but they are still widely used to determine where an individual is compared to others of the same age range.
Wechsler Intelligence Scale for Children
-
The Wechsler Intelligence Scale for Children, or WISC, is one of the most popular tests for children. It is a test administered to children between the ages of six and 16 years 11 months. The test consists of verbal and performance IQ sections, each of which measure multiple related subsets, including vocabulary, arithmetic, picture completion and mazes. Both sections are scored individually and are also used to formulate an overall score based on an average of 100.
Stanford-Binet Intelligence Scales
-
The Stanford-Binet Intelligence Scale is another of the most widely administered intelligence tests and is suitable for children and adults, from two years old into adulthood. However, it is considered most appropriate for children, teens and young adults. The test consists of four sections, which include verbal reasoning, abstract/visual reasoning, quantitative reasoning and short-term memory. The content of the test varies depending on the taker's age, as does the score.
Woodcock-Johnson
-
The Woodcock-Johnson Tests of Achievement are geared for all ages two years and up. Unlike the WISC and Stanford-Binet, the WJ test measures how well an individual student is performing in academic areas. There is also a WJ cognitive test that is more similar to a traditional IQ test. The two tests were designed to measure any discrepancies between a student's achievement and intelligence.
Kaufman
-
The Kaufman Adolescent and Adult Intelligence Test, or KAIT, is a highly reliable IQ test appropriate for children and adults over the age of 11 years. The test is comprised of two sections, the core battery and expanded battery, which tests 16 subsets, six of which are included in both sections. There are specific rules that must be adhered to in order to guarantee accuracy, so proctors must be trained to administer the test.
