Is the CertifiedIQ test reliable?

Yes. Our assessment is based on Raven's Progressive Matrices (RPM), the gold standard for measuring fluid intelligence. We use a database of 1.4M+ certified results and neural networks calibrated monthly by psychologists to ensure high accuracy.

What is the test based on?

The test is built on Raven's Progressive Matrices, a well-validated psychometric framework used in clinical and academic settings worldwide. Our 25 matrix puzzles measure pattern recognition and logical reasoning abilities.

How accurate are the results?

Our AI neural network is calibrated monthly by certified psychologists to ensure the highest accuracy across European demographics. Many users report scores within a few points of their Mensa or clinical assessments.

How is the test scientifically validated?

A specialized team of psychologists and data scientists has trained our own AI to deliver precise, personalized results. The methodology aligns with European psychometric standards and fluid intelligence (Gf) models.

What does the test measure?

The assessment measures fluid intelligence (Gf) through non-verbal visual matrix puzzles. It evaluates your ability to recognize patterns, complete sequences, and apply logical reasoning.

How long does the test take?

The assessment includes 25 questions and typically takes around 15 minutes. There is no time limit per question, so you can think through each puzzle at your own pace.

Are results comparable to other IQ tests?

Yes. Because we use Raven-style matrices, scores are comparable to those from other standardized tests. Many users who have taken Mensa or clinical assessments find their CertifiedIQ result aligns closely.

Is there a time limit per question?

No. You can take as long as you need on each question. This reduces pressure and allows you to perform at your best.

No. It is a professional certification product—not a casual free quiz. See the Pricing section on this page and the dedicated Pricing page for how billing works; full terms are shown before you pay.
