SAT to IQ conversion chart

Estimate your IQ, using your SAT score
Straight talk on it.

For all SAT conversions, the chart below seems to work better than any other method. Two well known data points fit it - for George W. Bush and Al Gore (their details below the chart).

The first IQ column (15 points for a Standard Deviation) applies to the most common IQ scale.

This chart seems to predict IQ scores well, as with Bush and Gore below - without "recentering"

President George W. Bush scored 566 verbal and 640 math in his SAT's, for a total of 1206. On the chart above, 1206 translates to 124 IQ in the first column (the more common 15 Standard Deviation in IQ). This is quite close to the 125 estimated by The Bell Curve author Murray for a 1206 combined SAT. See how Bush compares to other Presidents' IQ and social skills.

Al Gore, Bush's 2000 opponent got 1355 on his SAT, or 134 IQ on the chart above. This matches well with the IQ's of 133 and 134 Gore received in IQ tests he took at the beginning of his high school freshman and senior years. See press report http://www.upi.com/view.cfm?StoryID=20040114-074349-3947r

SAT to IQ conversion is an inexact science, particularly for SAT's under 900. This chart is with permission from http://members.shaw.ca/delajara/SATIQ.html The chart's creator writes: "I did these calculations using a method similar to that for my GRE to IQ Estimator. The lowest point of reference was the theoretical average IQ of high school students being 110 and the current average SAT I V+M (verbal + math) score being 1019. Everything below that is extrapolation. Also note that the decimal places give the impression that the numbers are more precise than they really are." There has been an independent verification of the accuracy of that GRE to IQ estimator (at the high end).
