Every test and article on this site is published by one company. These are its registration details, what it does, and what it deliberately does not claim.

GPWEBMEDIA is a web development company. On this site, what we contribute is the software: the generator that produces every test question, the scoring code that converts answers into a score on the standard 100/15 scale, and the platform that runs it all. Our full method is documented at how we score.
All test items on CheckIQFree are generated by our own software and owned by us. No question on this site is taken from another test publisher.
We are not psychologists and hold no qualifications in psychometrics. Nobody at this company is qualified to diagnose anything, and no result produced here is a clinical assessment.
Articles are drafted with the assistance of AI language models, then edited and fact-checked by us before publication. We are stating this because you should know it, not because anyone requires us to.
Articles covering sensitive subjects — children, low scores, careers, and the scoring method itself — are additionally reviewed before publication by Trần Thị Cẩm Giang, who holds a bachelor’s degree in Psychology from the University of Da Nang – University of Science and Education (2022). She works at GPWEBMEDIA, so this is internal review rather than independent review, and we would rather say so than let you assume otherwise. She is not a licensed psychologist and does not diagnose anything.
Articles that have been through this process carry her name and the review date at the top of the page. Articles without that line have not been reviewed, and we leave the line off rather than implying coverage we do not have.
This limits what we are willing to claim, and deliberately so. We describe what scores mean statistically, we cite our sources, and we do not interpret anyone's individual result. Where we are uncertain, we say so on the page. Our full method is set out at how we score.
An earlier version of this site published articles under an author profile that did not correspond to a real person. That profile has been removed and this page replaces it. We would rather correct it openly than quietly delete it.
If you find an error — a question with two valid answers, a factual mistake in an article, a score that looks wrong — please tell us. We publish corrections on the page concerned and note the date.
This site is free and carries advertising through Google AdSense. Advertisers have no say in test content, scoring, or anything we publish. We do not accept paid placements in articles.
