What are some commonly used intelligence tests, and how do I know which one is best for my child?
Numerous intelligence tests are available and are designed for different age groups and reflect the respective test developer’s philosophy regarding intelligence. Most IQ tests ask questions that assess both fluid (ability to solve new problems) and crystallized (knowledge gained through experience) intelligence. Some can be group administered while others require individual administration. Many IQ tests have test score ceilings of around 160. If a child scores 145 or above on such tests, it is often recommended that they be given a test with a higher ceiling (200 +) to ensure that their abilities are accurately measured. In addition, nonverbal measures of intelligence have been developed. These measures are often recommended for children who show visual-spatial strengths, are from culturally diverse backgrounds, are deaf or hard of hearing, or who speak limited English. Most IQ tests are protected and can only be administered by a qualified professional.
