What This Site Is
iqtest.quest is an online IQ test made of picture puzzles. It works in 25 languages, for children from age 4 and for adults, and shows the estimated IQ, percentile and cognitive title free right after the test.
We built it for people who are curious about how they think: adults who want a quick and honest look at their reasoning, and parents who want a playful first look at how their child solves picture puzzles. The test is meant for self-discovery and entertainment, not for diagnosis or for decisions about school or work.
What We Promise
-
The result is free
You see your estimated IQ, percentile and cognitive title without registering, without giving an email address and without paying.
-
No subscription
A detailed report is an optional one-time purchase. There are no repeat charges and nothing to cancel.
-
Honest limits
Scores use a provisional scoring model, not norms from a representative population sample. We say so on the result, in the report and in the methodology.
-
Little data
The test needs no account. We ask for an email address only when you buy a report, we do not sell data, and web analytics loads only with your consent.
-
Care with children
The youngest children take the test with a parent, and a young child's certificate shows strengths instead of an IQ figure.
How the Test Is Made
Every task is an original picture puzzle written for this site, not copied from published tests. Each task has exactly one correct answer, proved by a formal check before the task is used, and the pictures contain no words.
Tasks, answer keys, forms and scoring parameters ship together as a numbered release. A result keeps the release it was calculated with and is never recalculated later. When the scoring model is calibrated on real results, the change will come as a new release, and the methodology page will say so.
How Our Texts Are Written
The methodology, the report texts and the blog articles are written and checked by the team that builds the test. Claims about intelligence and IQ rest on published research, and every article lists its sources with links.
Each article shows the date of its last update. When the research or our test changes, we revise the text and its date.
If you find a mistake, write to support@iqtest.quest or use the contact form. We check every report and correct the text.
