On the reference scale, 130 sits in the very high range, around the 97.7th percentile. Here is what that means, and what it does not.
Prepared by IQInsight · Calculation guide · Updated
130 is exactly two standard deviations above the model mean.
The calculation is (130 - 100) / 15 = 2. The standard normal curve places about 97.72% of values below that point, leaving 2.28% at or above it. “Top 2%” is a rough shorthand, not the exact percentage.
At 125 the upper tail is about 4.78%; at 130 it is about 2.28%. That tail is roughly halved even though the score changes by five points. This is a property of the normal curve, not evidence that one person has twice the ability of another.
How the percentile is calculated.
The reference uses a mean of 100 and a standard deviation of 15. First convert the score to a z-score, then find the area below it on the standard normal curve.
Theoretical normal distribution. Mean 100, standard deviation 15. This does not measure your IQ or compare you with IQInsight users.
Put the number in perspective.
In a normal distribution with mean 100 and standard deviation 15, about 2.28% of scores fall at or above 130. That is approximately one in 44. The figure describes the reference model; it is not a count of people we have tested.
The quality of the test matters.
A number alone does not show how accurately it was measured. An established, professionally administered test has supporting evidence and defined interpretation rules. An online exercise without representative norms cannot establish the same conclusions.

Looking at the answers can be useful even when a score is only provisional. Which patterns did you notice? Which constraints did you overlook? Those are concrete things you can review without treating a single number as your identity.
Does a 130 result automatically establish giftedness?+
No. A threshold on a mathematical scale is not a complete assessment. Interpretation depends on the specific instrument, its norms, reliability and intended use. An uncalibrated IQInsight estimate cannot establish a formal classification.
Is 130 a good IQ score?+
On a theoretical scale with mean 100 and standard deviation 15, 130 is in the very high range, around the 97.7th percentile. Whether a particular test result supports that interpretation depends on the quality and standardization of that test.
How rare is an IQ of 130?+
Under that normal-distribution model, about 2.28% of values are at or above 130, approximately 1 in 44. This is a mathematical reference, not observed IQInsight user data.
Does this number describe all of my abilities?+
No. IQ scores do not describe every skill, interest, quality or circumstance. A score on an unstandardized online exercise is especially limited and should not be treated as a diagnosis or a prediction of personal success.
Can I compare scores from different tests?+
Only with care. Tests can differ in norms, scales, questions, administration and reliability. Similar-looking numbers are not necessarily equivalent measurements.
Can I get my result without paying?+
Yes. IQInsight is designed to provide the estimated score, theoretical percentile and all four domain breakdowns for free. The optional report explains the answers in more detail.
