What Is WIQS?

WIQS stands for World IQ Scoring. WIQS is an online IQ testing service designed to help you explore reasoning and problem-solving through visual, numerical, and logical questions.

We are collecting test data from participants around the world to develop and refine the WIQS scoring model. WIQS is an online reference test, not a clinical assessment administered by a psychologist.

What Does the WIQS IQ Test Assess?

• Logical reasoning — identifying rules and relationships
• Pattern recognition — finding patterns and missing elements
• Numerical processing — recognizing relationships between numbers
• Spatial awareness — understanding shapes and visual relationships
• Processing speed — solving problems within a time limit

Questions are designed to minimize the influence of culture, language, age, educational background, gender, and color vision characteristics as much as possible.

Try an IQ Question

Try to solve the following IQ question as an example!

Answer

D. Each row cycles the same three shapes — circle, triangle, and square — one position to the left. Following that pattern, the missing figure is the unfilled (outline) triangle.

Help Build a New IQ Scoring Model

WIQS is collecting test data from people around the world to develop and refine its scoring model. By participating during this early stage, you can contribute to the development of a new online IQ testing service.

After completing the Official Test and verifying your email, you can see your result — estimated IQ, margin of error, and rank — right away on the results screen. We plan to email a free Detailed Intelligence Analysis Report once enough data has been collected.

Before You Begin

Take the test in a quiet place where you can concentrate. To see your result, you will need to provide and verify your email address. Please review the instructions shown during the test.
