Start with your purpose
Practice, curiosity, clinical assessment, school support, and membership decisions require different evidence. An online test may suit curiosity, while a consequential decision usually requires an approved, supervised assessment.
Check the intended age range, language, accessibility, time requirements, score explanation, and privacy terms before beginning.
Create fair testing conditions
Use a reliable device, stable connection, quiet setting, and enough uninterrupted time. Follow the stated rules and avoid calculators, searches, hints, or another person unless explicitly allowed.
Choose the language you understand best and use any permitted accessibility settings before the timer begins. Consistent conditions make the result easier to interpret.
Read the result as an estimate
Review the score range, percentile, tested domains, and stated uncertainty rather than focusing on one number. A surprising result can reflect conditions or a mismatch between you and the format.
Do not use an unsupervised online score as a diagnosis or official credential. Seek a qualified professional when the result will guide care, education, or another important decision.
Common questions
Frequently asked questions
Should I study before an IQ test?
Learn the instructions and arrive rested, but memorizing repeated items can make the score less representative.
Can I use a calculator?
Only when the test explicitly permits it. External tools otherwise change what the test is measuring.
