Where 95 sits on the IQ scale
A score of 95 is 5 points below the mean. Dividing by the standard deviation gives (95 − 100) ÷ 15 = -0.33. The normal cumulative distribution converts that standardized position into percentile 36.94.
This lies in the lower half of the central 85–115 interval. A position below the mean is a comparison with the scale center, not a statement that every reasoning skill is below average.
How common is a score of 95?
Approximately 36.94% of this model lies at or below 95—about 1 in 3. This is a cumulative share, not the chance of scoring exactly 95. A continuous model does not assign a positive probability to one exact value.
Compared with IQ 85, the reference percentile is 21.08 percentage points higher. Equal IQ-point gaps do not create equal percentile gaps: the middle of the bell curve contains more area than its ends.

How this relates to starp
starp's current 30-question scoring map produces 95 from 21 correct answers (70% correct). That accuracy percentage is different from the normal-model percentile above. The scoring map was calibrated with 12,700 simulated assessments; it is not population norming.

Questions about IQ 95
Is 95 a good IQ score?
95 is below the reference mean of 100. It should be interpreted in the context of the test, rather than as a verdict on a person's abilities or future.
What percentile is an IQ of 95?
On a normal scale with mean 100 and standard deviation 15, 95 corresponds to approximately percentile 36.94. Around 63.06% of that model lies at or above it. Use an assessment's own norms for an actual reported rank.
Does an IQ of 95 mean 95% correct?
No. IQ is a scaled score. Percentage correct depends on the questions and scoring rules; percentile describes a relative position. These three quantities are not interchangeable.
