This site offers information and products relating to IQ testing, especially for children considering enrollment in Gifted and Talented programs. Regardless of how you feel about IQ tests, some people who think they are important may use information from them to make decisions about your child's future. While there is a clear statistical correlation between IQ scores and academic success, we're also confident that performance on IQ tests can be improved through preparation.
We offer books, test materials, and preparation materials to help improve scores. Many children enjoy taking the tests, which are designed to be interesting and fun. People often ask the same questions. Here is a start at a Frequently Asked Questions (FAQ) page on IQ testing.
Note that most professional testing materials are not available to non-professionals. We offer these here primarily for researchers and those professionals who can't get an older version from the original publisher.
We occasionally buy collections with other psychology tests.
