The team of psychologists who created the test at IQTest.com were given the task of developing a valid, reliable, and fun test that could be taken online. This was a new thing in 1994 when the test first went online.

Not just any test can be taken online. Most of the tests found online today do not give valid IQ scores.

The most recent versions of the Stanford-Binet and the Wechsler Adult Intelligence Scale have the same standard deviation as our test, i. E., 15, and will produce scores that can be compared to the scores received on our test.

We offer the test as entertainment because we cannot control the test environment, but many people who know their scores from either the Stanford-Binet or the Wechsler Adult Intelligence Scale tell us that they scored within a few points of their previous scores when they took our test.
