Scientific IQ Assessment: The Most Accurate Online Intelligence Test

Our assessment shows a 98.7% correlation with the WAIS IV, the gold standard in IQ testing. This means our results are highly consistent with what you would receive from a professional psychologist. The adaptive nature of our test actually allows for greater precision because questions adjust to your exact ability level.

Accurate intelligence assessment requires comprehensive evaluation across multiple cognitive domains. Our 60 question adaptive format ensures we gather sufficient data points while the algorithm optimizes for efficiency. Shorter tests sacrifice accuracy for convenience. Think of it like a medical checkup versus a quick symptom checker.

Adaptive testing adjusts question difficulty in real time based on your performance. If you answer correctly, questions become harder. If incorrect, they become easier. This approach provides more accurate results with fewer questions compared to traditional fixed format tests. It also reduces test anxiety by keeping you in your optimal challenge zone.

Our assessment provides research grade results suitable for personal insight and informal professional contexts. For official purposes like Mensa admission, clinical diagnosis, or legal proceedings, you will need an in person assessment by a licensed psychologist. However, our results can help you decide if pursuing official testing is worthwhile.

We recommend waiting at least 6 months between attempts to minimize practice effects. Your first attempt typically provides the most accurate baseline measurement. Significant score improvements usually require genuine cognitive development through training, not repeated testing.

We employ bank level encryption and comply with GDPR, CCPA, and international privacy standards. Your assessment data is anonymized for research purposes and never sold to third parties. You maintain full control over your data and can request deletion at any time. Only you can see your detailed results.
