We're on a mission to make scientifically validated intelligence testing accessible to everyone, helping millions understand their cognitive potential.
Best IQ Test was founded in 2018 by a team of cognitive psychologists and data scientists who saw a gap in the market for accessible, scientifically rigorous IQ testing.
Traditional IQ tests required expensive appointments with psychologists, putting accurate cognitive assessment out of reach for most people. We set out to change that by developing an online platform that maintains scientific standards while being accessible to anyone with an internet connection.
Today, over 1 million people have taken our tests, and we continue to refine our methodology based on the latest research in cognitive science.
We believe that understanding your cognitive abilities is the first step toward personal growth. Our mission is to provide accurate, accessible, and actionable intelligence assessments that help people:
Discover their strengths - Identify areas where you naturally excel, from logical reasoning to pattern recognition.
Identify growth opportunities - Understand which cognitive skills can be developed through targeted training.
Track progress over time - Monitor how your cognitive abilities evolve with practice and training.
Our tests are developed in collaboration with leading researchers in cognitive psychology and psychometrics. We follow established protocols for test development and validation.
Each question is carefully calibrated using Item Response Theory (IRT) to ensure accurate measurement across the full range of cognitive abilities. Our scoring algorithms are regularly updated based on normative data from our growing user base.
We maintain transparency about our methodology and publish regular reports on test validity and reliability.
The principles that guide everything we do
We never compromise on scientific rigor. Every test we develop meets the highest standards of psychometric validity and reliability.
Intelligence testing should be available to everyone. We work to remove barriers and make our platform accessible globally.
We constantly refine our tests based on the latest research and user feedback, ensuring the best possible experience.
