While performance differences between boys and girls have narrowed considerably, boys still outnumber girls by more than about 3-to-1 at extremely high levels of math ability and scientific reasoning.
At the same time, girls slightly outnumber boys at extremely high levels of verbal reasoning and writing ability.
Those are the findings of a recent study that examined 30 years of standardized test data from the very highest-scoring seventh graders. Except for the differences at these highest levels of performance, boys and girls are essentially the same at all other levels of performance.
The findings come from a study performed by Duke University's Talent Identification Program, which relies on SAT and ACT tests administered to the top 5 percent of 7th graders to identify gifted students and nurture their intellectual talents. There were more than 1.6 million such students in this study.
