In our ranking of official IQ tests, we highlight websites and tests backed by registered companies or legal entities. This category is crucial for ensuring the reliability of services, as having an established entity behind a product means there are individuals or organizations willing to take responsibility for the quality of their offering. This is a key factor to consider when choosing a test.
While being developed and managed by a legal entity adds a layer of accountability, it does not automatically guarantee that the test will offer the most accurate or high-quality results. However, it does indicate that the organization is prepared to stand behind its product.
If you prefer to engage with a service offered by an established company and want to purchase or interact with the site with confidence, this list will be helpful for you. It ensures you can collaborate with reliable, established organizations.
If having a registered company behind a test is your most important criterion, then yes, this list is an excellent place to start. However, even though these companies may stand behind their products, it does not always mean they offer the best or most accurate tests. This is why we provide detailed descriptions and comprehensive ratings for each test in our listing. Ultimately, the choice of which test to take rests with you.
