How good is 127 for IQ score for a thirteen year old?

Answer 1

IQ has absolutely nothing to do with age. An average IQ for ANY age is around 100.

+++

So 127 is good - but remember that it measures only artificial puzzle-solving prowess, and is NOT a reliable guide to learning ability or academic progress.

Answer 2

No. IQ is not related to age. If you have an IQ of 72 now, you'll have one forever.

The average is, by definition, 100.

Tell people you have an IQ of 132. No one will question it.

IQ Scores & Ratings Lewis Terman (1916) developed the original notion of IQ and proposed this scale for classifying IQ scores: * Over 140 - Genius or near genius * 120 - 140 - Very superior intelligence * 110 - 119 - Superior intelligence * 90 - 109 - Normal or average intelligence * 80 - 89 - Dullness * 70 - 79 - Borderline deficiency * Under 70 - Definite feeble-mindedness The properties of the normal distribution apply to IQ scores: * 50% of IQ scores fall between 90 and 110 * 70% of IQ scores fall between 85 and 115 * 95% of IQ scores fall between 70 and 130 * 99.5% of IQ scores fall between 60 and 140 Remember they have different tests for different ages. This is based off of Lewis Termans test created in 1916. Look up 'Intelligence quotient' at wikipedia dot org for more information.
