This increase in IQ scores has been going on for over 100 years or so, and the tests are calibrated every 10 years, so that the average score is 100 and the first standard deviation is at +- 15. When current generation of students take the current test, their average is 100. If the same people are given the previous test, calibrated 10 years earlier they generally score around 103, which is 3 points higher than the generation which originally took the test. It is thought that people from the 1930s would score around 85 on today's tests.
