– This test originated from a university project by psychology graduates. As part of our commitment to rigor, we want to inform you of the following: Your score is calculated by comparing your performance to other test-takers. For instance, only 0.1% of test-takers get all the answers right. If you are one of them, this means you performed better intellectually than 99.9% of test-takers. This methodology might give a general idea of your intellectual ability and even a broad estimate of the range where your IQ stands. However, this is not an IQ test with diagnostic value. No online test has diagnostic value. Only in-person tests administered by a professional can accurately assess your IQ. Thus, the material on this site should not be relied upon for making any sort of diagnostic decisions.

What is an official IQ Test exactly?
An official IQ test could be defined as an IQ test that is able to produce valid and reliable results that have diagnostic value. That’s what people commonly refer to by “official”. An IQ test that could be regarded as accurate must have an acceptable degree of psychometric validity and reliability. Tests such as the Raven’s, the WAIS (Weschler Adult Intelligence Scale), or the Stanford Binet scale, are good examples of “official” IQ tests.
A test is said to have “psychometric validity” if what is being measured correlates with what the test actually intends to measure. Roughly speaking, if a test measures intelligence, it should correlate with how smart test-takers are, and not with, for instance, how high their emotional intelligence or their social skills are.
Last, an IQ test is said to have psychometric reliability if it produces the same results (or very similar ones) after each administration.
This concept is very easy to understand. If we measure the temperature of an object several times and we obtain a different result in each measurement, (let’s assume the real temperature was the same all the time) it will mean that our thermometer is not reliable; it is probably broken. The same applies to IQ tests and other psychometric tools.
Where to take an Official IQ test?
The best place to take an official IQ test are psychology clinics. However, you might also get assessed in any HR firm or HR department willing to test you, in any faculty of psychology (which was also willing to test you) or even at school (provided the psychology office has the necessary knowledge and resources).
However, what most people who want to take a real IQ test do is just go to a psychologist/psychology clinic that is trained in administering these tests. The entire testing process can cost between $300 and $1000.
Another place where you can take an “official” IQ test is the Internet; you can just take an IQ test online. Online IQ tests might give a broad (very broad) estimate/approximation of someone’s IQ and are really good for practice purposes. However, they should not be used with diagnostic purposes or for drawing definitive conclusions. Online IQ tests are offered for informational or recreational purposes and not for being used as a valid assessment tool. No online IQ test can be as accurate as an in-person test administered by a professional.
