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 See more detail at http://wilderdom.com/intelligence/IQWhatScoresMean.html

Be careful with IQ tests though - remember the words of Henry H Goddard, the man who gave us words like 'moron' 'eugenics' etc! The whole range below 70 has also been defined: 70-80 Borderline deficiency 50-69 Moron 20-49 Imbecile below 20 Idiot I have also read that below 10 = cretin - can't remember the source though. http://www.iqcomparisonsite.com/IQBasics.aspx
