Intelligence testing began in the early 20th century, when psychologists such as Alfred Binet and Theodore Simon sought to assign school-age children an intelligence quotient, or IQ, which would help determine whether they needed additional educational assistance. There are now dozens of IQ tests available online to give you a free assessment of your child's IQ (see Resources for links).

Queendom's general IQ test is designed to measure the following factors of intelligence: logic and math skills, language abilities, spatial relations, general knowledge and solving novel problems. There are 109 questions in all, and your child will have 40 minutes to complete the test. Upon completion of the test, you'll receive a score and a personalised report on your child's performance.

Athey Education Verbal Reasoning Test
The Athey Education site has an IQ test that measures children's verbal reasoning skills. The test is intended for children ages nine to 12. Your child will have 13 minutes to answer as many of the 25 questions as she can. When she is done, you'll receive a score report with the percentage of questions she answered correctly and how she compares with other children her age.
