Average IQ by education level: how to read this comparison
Participants with more completed education tend to score higher on IQ-style tests - but the comparison is about group averages in a self-selected dataset, not about what education does to intelligence. Here is how to interpret it honestly.

What this comparison measures
The education comparison groups participants by the highest level of education they reported completing, and compares test performance across those groups. Each group's average comes from participants who chose to share that detail, not from a representative sample of the population.
Two cautions follow from that design: people who take an online test are already a self-selected group, and self-reported education is not independently verified. The numbers describe this dataset, not entire countries.
The levels being compared
The site uses a simplified ladder based on common education categories. Labels differ between countries, so the groups are broader than they sound:
| Level | What it usually means |
|---|---|
| Primary or secondary | Compulsory schooling or a secondary school certificate |
| Post-secondary non-tertiary | Vocational or technical training after secondary school |
| Short-cycle tertiary | Two-year degrees and similar qualifications |
| Bachelor's or equivalent | A completed undergraduate degree |
| Master's or equivalent | A completed postgraduate degree |
| Doctorate or equivalent | A completed doctoral-level degree |
Why scores and education correlate
Higher average scores in more educated groups are expected, and they do not mean that education raises intelligence directly. Longer education partly selects for people who perform well on reasoning tasks, and test familiarity - practice with standardised questions - improves performance independently of underlying ability.
Socioeconomic conditions influence both pathways: they shape who continues in education and who has the free time to take an online test in a quiet setting. None of this can be untangled from an anonymous comparison chart; that is a limitation, not a feature.
How to use the education page
Treat the education page as a description of who took this test and how the groups differ, and use your own percentile as the main takeaway: it places your performance within the group you chose to compare against.
On the result page, the education comparison requires the detail you optionally add; without it, no education percentile is computed for your attempt.
What the pattern cannot tell you
It cannot measure your intelligence as an individual, cannot establish a diagnosis, and cannot predict success in any specific course or job. Group averages also move as the dataset grows, because the norms are recalculated as new attempts arrive.
Anyone claiming that an education-based comparison proves something about intelligence - for you or for a group - is overreading the data. The methodology page documents the assumptions and limitations behind these numbers.
Frequently asked questions
Do people with more education have higher IQ scores?
In this dataset, average scores are higher in groups with more completed education. Because participants are self-selected and education is self-reported, the comparison is descriptive - it cannot prove that education causes higher scores.
Does education make you more intelligent?
Education builds knowledge and test-taking skill, and it partly selects for people who perform well on reasoning tasks. An online dataset like this one cannot separate those effects.
Why compare scores by education at all?
The comparison is a reference point for interpreting a result - your percentile is computed within a chosen group. It is descriptive information about the dataset, not a judgment about any individual.
Where can I see the education distribution?
The average IQ by education level statistics page shows group sizes and averages, and the dataset overview explains how the numbers are computed and refreshed.
