What it measures
What you happen to know across science, history, geography and the arts.
Your score is read against adults generally. The bands below come from the shape of a normal distribution, which is the model the scoring assumes rather than a count from a reference sample. Most people sit in the middle and both ends are rare by definition, so a band is a position in a distribution, not a verdict.
Good uses
- A light check on breadth of knowledge.
- Finding the areas where your knowledge is thin.
- Comparing your result against the other forms on this site.
Known limits
- Knowledge is not reasoning ability, and the two only partly overlap.
- Items written in one language and setting do not travel perfectly to another.
- An unsupervised online test is not a clinical assessment and is not an IQ certificate.
