Average IQ score
On the IQ-style scale used here (mean 100, standard deviation 15), scores around 100 are most common. In a normal distribution, about two-thirds of people fall roughly between 85 and 115, and many tests describe 90-110 as a 'typical' range. Below you'll see average scores for several categories based on results from test-takers on UniversalIQTest.com. These summaries reflect our dataset and may change slightly as more people take the test.
Average IQ by age
You can see the categorization of the ages on the y-axis and the average IQ on the x-axis. This website categorizes youth ages 12 to 18, young adults ages 19 to 35, adults ages 36 to 65, and seniors ages 66 to 100.
Average IQ by gender
The chart above shows the average score by gender among test-takers on UniversalIQTest.com. Any differences are typically small and should be interpreted in context of sample size and the fact that this is a self-selected online dataset.
Average IQ by education level
The relationship between intelligence and education is one that scientists have been studying for years. It is true to say that a higher level of education leads to a higher level of intelligence and vice versa, but it is not true in every situation.
On this website, we differentiate between 6 education levels.
- Primary/secondary education level
Definition: Programmes are typically designed to provide students with fundamental skills in reading, writing and mathematics and to establish a solid foundation for learning. After that, it builds on secondary education, typically with a more subject-oriented curriculum. Second/final stage of secondary education preparing for tertiary education and/or providing skills relevant to employment. Usually with an increased range of subject options and streams.
- Post-secondary non-tertiary education level
Definition: Programmes provide learning experiences that build on secondary education and prepare for labour market entry and/or tertiary education. The content is broader than secondary but not as complex as tertiary education.
- Short-cycle tertiary education level
Definition: Short first tertiary programmes that are typically practically-based, occupationally-specific and prepare for labour market entry. These programmes may also provide a pathway to other tertiary programmes.
- Bachelor's or equivalent
Definition: Programmes designed to provide intermediate academic and/or professional knowledge, skills and competencies leading to a first tertiary degree or equivalent qualification.
- Master's or equivalent
Definition: Programmes designed to provide advanced academic and/or professional knowledge, skills and competencies leading to a second tertiary degree or equivalent qualification.
- Doctorate or equivalent
Definition: Programmes designed primarily to lead to an advanced research qualification, usually concluding with the submission and defence of a substantive dissertation of publishable quality based on original research.
Average IQ by study area
Physics, Mathematical Sciences and Philosophy are among the majors with the highest IQs, according to research. This can vary depending on the country. Here you can see the study area on the y-axis and the average IQ measured on the x-axis.

UniversalIQTest.com Statistics
Our statistics above are based on the measured data of all candidates worldwide and may evolve depending on the new results recorded.
Furthermore, we complement each IQ result with personalized statistics that assess the candidate based on various parameters (population, age category, gender, study level, study area).
Our statistics can change over time since every result is stored in our database. The more results we store, the more accurate the statistics will be. The calculation of the IQ scores is done in real-time.
Quality Assurance and Test Validation
At UniversalIQTest.com, we take the integrity of our IQ test rankings very seriously. To ensure that every ranking reflects genuine test-taker performance, we have implemented a robust validation system that automatically reviews each test submission. This process checks that tests are completed with proper care and deliberation.
Our system is designed to identify and flag submissions that may not represent an authentic testing experience. Tests that do not meet our quality criteria are excluded from the ranking process, ensuring that our results remain fair and reliable for all users.
We continuously monitor and update our validation methods to maintain the highest standards of accuracy and credibility. Rest assured, our commitment is to provide you with trustworthy and meaningful insights into IQ performance.
IQ score calculation on UniversalIQTest.com
On UniversalIQTest.com, the IQ score is normalized with a mean of 100 and a standard deviation of 15. Our test is constructed so that the results are approximately normally distributed for a sufficiently large population sample. The IQ test score takes one's age, the number of correct answers and the completion time into consideration for the ranking. After that, a so-called percent rank (from 0-1) is calculated and normalized with the bell curve (mean 100 and deviation 15) in order to calculate the IQ score. This IQ score is dynamic and can change over time, as more and more people take this IQ test your percent rank can change. Once you completed your test you can visit your result page and see your score change and adjust in real-time. The score won't change significantly because over 250,000 people have taken this test already.
Online IQ test types
Most online IQ tests fall into two broad categories: raw-score tests and normed (rank-based) tests.
Raw-score tests (often free)
These tests typically convert 'number correct' directly into an IQ number using a fixed table. They usually don't use robust norming against a large reference sample, and they often ignore factors like age groups and test-taking behavior. The result can look precise, but the score may not be comparable across different users or over time.
Normed tests (often paid)
These tests first compare your performance to a reference group (a percentile rank) and then map that percentile to an IQ-style scale (commonly centered around 100 with a standard deviation of 15). This approach is generally more meaningful because it's based on how you performed relative to others, not a static conversion table. Even with norming, quality varies: some sites use small samples, don't separate age bands, or don't apply checks against rushed/random attempts, each of which can distort results. This test uses ongoing norming on a large dataset and publishes methodology/limitations.
IQ classification
Many IQ tests report scores on a bell curve (normal distribution) with a mean of 100 and a standard deviation of 15. On such a scale, a score near 100 is typical, and scores become less common as you move farther away from the center.
How common are different ranges?
About 68% of people fall within 85-115 (within 1 standard deviation). About 95% fall within 70-130 (within 2 standard deviations). Only about 2% score 130+ and about 2% score below 70. Common descriptive ranges (wording varies across tests and publications):
130+
Very high
115-129
Above average
85-114
Average
70-84
Below average
<70
Very low. These categories are not a clinical assessment. This website provides an IQ-style score based on performance and norming within our dataset, so it's best used as a structured indicator rather than a diagnosis.
Frequently asked questions
What is the highest/lowest possible IQ?
On UniversalIQTest.com the highest or lowest IQ scores are dynamic according to how many people took the test. Right now the highest possible IQ is 162 and the lowest possible IQ is 50. These numbers change over time the more people take this test.
What is considered an average IQ?
An average IQ score is between 85 and 115. 68% of IQ scores are within one standard deviation of the mean. This means that the majority of people have an IQ value between 85 and 115.
Why is there no time limit?
On UniversalIQTest.com we take the time for completion into consideration when ranking the candidates against each other. However, it is not necessary for a time limit because the time is being considered. For optimal IQ scores, you would need a completion time of around 30-40 minutes.
How accurate is this IQ test?
We score results using a large, continuously growing dataset of test attempts. Your result is converted into a percentile rank and then mapped to an IQ-style score, with context such as age and (to a limited extent) completion time. Because the norms are updated as the dataset grows, scores can shift slightly over time. Many online IQ tests use a simple number correct -> IQ table with no robust norming. That approach can be misleading, which is why we publish our methodology and dataset limitations openly.
