Acceptance of terms
By using IQ Test US (this website at iq-test.us) you agree to these Terms of Service. If you don't agree, please don't use the site.
Description of service
IQ Test US provides a free online IQ test based on the public-domain ICAR framework, together with educational content about IQ testing, cognitive assessment, and related topics. The service is provided "as is" with no warranty of any kind.
The service is intended for self-discovery, curiosity, and educational purposes only. It is not a clinical, diagnostic, employment, or legal instrument.
Not a clinical assessment
Our test is not:
- A clinical IQ assessment (such as the WAIS-IV or Stanford-Binet, which require licensed psychologists)
- A valid basis for educational placement, gifted-program admission, or special-education evaluation
- A diagnostic tool for intellectual disability, learning disorders, or developmental conditions
- An employment screening or hiring tool
- A valid measure for legal, immigration, or research purposes
If you need an IQ score for any of these purposes, consult a licensed psychologist or qualified professional.
No professional advice
Content on this site — including blog posts, hub guides, and FAQ answers — is informational and educational. It does not constitute psychological, medical, legal, educational, or financial advice. Do not rely on our content as a substitute for professional consultation.
Disclaimers
The service and all content are provided "as is" and "as available" without warranty of any kind, express or implied, including warranties of accuracy, merchantability, fitness for a particular purpose, or non-infringement.
We do not guarantee that the service will be uninterrupted, error-free, or that scores produced are clinically accurate. Score interpretation has known limitations described in our About page.

Limitation of liability
To the maximum extent permitted by law, IQ Test US and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of (or inability to use) the service, including but not limited to decisions you make based on test results, content read on this site, or external links.

Changes to these terms
We may update these terms periodically. Material changes will be noted on this page with the new effective date. Continued use of the service after changes constitutes acceptance.
