- As of December 2010, the IQ test administered to students between the ages of six and 16 is called the WISC-IV test. There are 10 segments to the test, which provide overall score in four general areas: verbal comprehension, perceptual reasoning, processing speed and working memory. The four of these overall scores yield a full-scale IQ. The highest full-scale IQ from this test is 160.
- A full-scale IQ score evaluates multiple intellectual abilities. The IQ tests assesses a student's ability to reason abstractly given both verbal and visual prompts. The two final aforementioned sections of the IQ tests track a student's short-term auditory and visual memory, along with the time that a student needs to arrive at an answer.
- In most WISC-IV tests, verbal comprehension and perceptual reasoning scores are often higher than those for processing speed and working memory. Professionals at the Gifted Development Center in Denver believe that many students' IQ scores are brought down when timing is too heavily weighted.
