Purpose
Our articles are written to help readers understand IQ scores, cognitive assessment, percentile ranks, cognitive domains, and the limits of online testing. The content is educational and should not be treated as clinical advice.
Publishing Standards
Editorial Policy
IQ Test Center publishes educational material about IQ, cognitive assessment, and SAT preparation. This policy explains how public content is created, sourced, reviewed, updated, and kept separate from advertising.
Originality
Content should add its own explanation, examples, structure, or interpretation. We do not publish scraped articles, spun text, or pages whose only purpose is to host advertisements.
Sources and factual claims
For factual claims about professional assessment, scoring, research, test administration, or another organisation’s product, we prefer primary sources, professional associations, or the relevant publisher. We distinguish those facts from our own original teaching material. A third-party blog, social post, or AI-generated answer is not treated as a sufficient source for a factual claim.
Publisher responsibility and review
Zhiyuan Yang, founder and editor, is responsible for publication and editorial updates. Before a page is published or materially revised, we check that its links work, its public claims match the product experience, and its stated limits are clear. We do not imply an independent reviewer, clinical credential, or official affiliation unless one is real and named.
Updates and corrections
If a reader identifies an error, unclear statement, broken link, or outdated explanation, they can contact us through the Contact page. We review correction requests and correct material errors when supported. A changed date is used to reflect a real revision, not to create a false freshness signal.
Advertising separation
Advertising does not decide article conclusions or assessment scoring. Ads, when present, should not cover content, imitate controls, or appear as the main reason a page exists.
