What payment may include
A paid service may fund larger item banks, norming, professional administration, identity checks, detailed reporting, support, or secure delivery. It can also simply fund marketing or a decorative certificate.
A free test may still be thoughtfully designed, especially for education or practice, but it should state what evidence supports the score.
Questions to ask before paying
Check the total price, renewal terms, refund conditions, data retention, score access, certificate status, age range, language, and whether the result is accepted for your purpose.
Avoid claims that one short online number is a diagnosis, guaranteed admission credential, or complete account of intelligence.
Choose by purpose, not price
For curiosity, an honest free estimate may be enough. For clinical, educational, legal, or membership decisions, confirm which supervised instruments and documentation the receiving organization accepts.
Mensa International states that online tests cannot be used for admission. Payment for an online result does not change that rule.
Common questions
Frequently asked questions
Is a paid IQ test automatically official?
