Via Wired, an article about the Flynn Effect and the top 5% of students over a period of 19 years.

The Flynn effect is the gradual increase over time of people’s scores on many intelligence tests, from old IQ tests to Raven’s Progressive Matrices or the SAT. Until now, we haven’t had data on if the top performers were also experiencing these improvements.

The effect was found in the top 5% at a rate similar to the general distribution, providing evidence for the first time that the entire curve is likely increasing at a constant rate. The effect was also found for females as well as males, appears to still be continuing, is primarily concentrated on the mathematics subtests of the SAT, ACT, and EXPLORE, and operates similarly for both 5th and 6th as well as 7th graders in the right tail.

As to what is causing the Flynn effect— no one knows, yet. Or what this improved intelligence test performance even means.
