Accurate Standardized IQ Tests

Take a valid, standardized IQ test

Knowing your true IQ level requires that you take a scientifically valid and standardized IQ test. This gives you a score somewhere on the IQ bell curve below. With this ‘bell curve’ you can compare your score with others in the population. It is generally thought that an IQ of 115 or greater is needed for college level education. Mensa requires an IQ level of 130 – in the top 2% of the population. A high IQ can be considered to be 115-120 or above.

Professional IQ tests

They are typically administered by a certified psychologist, educationalist or clinician. They cost to you will be in the region of $300-$500 for an assessment. The test kits can be purchased independently – at a high cost: $1,110.00 for the test battery (link).

The GIQ Test is an online analog for the most common clinically proctored IQ tests. In our internal study, the GIQTest correlated within about 4% of an individual’s full scale score on a clinically proctored IQ test. The GIQTest’s sections are modeled after clinical IQ test sections.

The GIQ has the following features
