How accurate is the IQ percentile calculator?

The calculator uses standard IQ distribution norms with a mean of 100 and a standard deviation of 15. It provides a reliable statistical estimate based on entered scores but should not substitute for a professionally administered IQ test.

What IQ score represents the 95th percentile?

An IQ score of approximately 125 typically places an individual at the 95th percentile, meaning 95% of the population scores at or below that level, while 5% score higher.

Can this calculator determine giftedness?

Scores at or above 130 often fall into the gifted range, representing roughly the 98th percentile. However, educational or psychological evaluations are recommended for formal gifted identification.

Why do percentile ranks matter more than raw IQ scores?

Percentile ranks show how a score compares to the broader population, making it easier to understand relative standing. A score of 115 might seem high numerically, but at the 84th percentile, it clearly indicates stronger performance than roughly 84% of test-takers.
