5 Best IQ Tests in 2025

RIOT IQ test: Link here

The RIOT is valid for American, native English–speaking adults aged 18 and up. It does not contend with in-person tests like the WAIS—nor should it, given the irreplaceable value of proctored settings. RIOT exists in an altogether alternate category that offers a credible, convenient, and easily accessible format. Its validity and reliability data have now been gathered, confirming that its scores hold up to professional psychometric standards. What remains constant is the integrity and vision behind it: an entirely online IQ test that leverages modern software to assess reasoning and intelligence with scientific rigor. It is well within possibility that RIOT may even become a complementary assessment to tests like the WAIS (think colleague, rather than rival), helping to transcend the limitations of in-person testing and expand access to credible measurement virtually instead.

WISC-V: Link here

For children aged 6 to 16 years and 11 months, the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V), is my go-to recommendation. The WISC-V’s ability to provide both a Full Scale IQ and detailed index scores makes it indispensable for identifying giftedness or learning difficulties.

Yes, you would be right. There is only 1 online IQ test mentioned in the list of 5. This is because in-person IQ assessments are still the gold standard and accepted way to obtain the most accurate measure of IQ. But, online IQ tests have their place, and there has been critical need for a valid online IQ test. Our team (Riot IQ) saw this and started developing such a test in early 2024-- called the RIOT, or the “Reasoning and Intelligence Online Test”. We think it will be a valuable resource for psychologists, researchers, professionals and individuals alike. We spent over a year developing the test.

Our mission is to establish a new standard for online IQ testing, and restore confidence in the online medium as a valuable tool for cognitive assessment in specific scenarios. We acknowledge that online tests cannot fully replace in-person evaluations, but we want to offer a compelling alternative for specific situations where in-person testing is not feasible. For instance, the RIOT can serve as a valuable screening tool, providing preliminary insights before professionals administer comprehensive in-person assessments like the WAIS.

That's all for now. We will be maintaining this list and updating it as tests come and go. We hope you found this article helpful. Feel free to email us at research@riotiq.com with any questions.
