That's the headline on yesterday's article in the New York Times. While the city's schools as a whole are about 51% male, the gifted programs in the early grades are about 55-56% female.
What causes the disparity? Some experts say that little girls are better able to sit still during the exams required for entrance to these programs. Girls may also develop verbal skills at an earlier age, and hence be able to communicate their giftedness to adults better. (I guess we can be grateful, for the cause of gender relations, that experts aren't suggesting that girls are smarter than boys -- a reverse of the way people spun Larry Summers' comments a few years ago).
If these gender differences are true, though, what is to be done about it? I suppose the same things many of us advocate for making gifted programs fair on multiple dimensions (race, class, etc). Use multiple assessments. Allow people to test in (and out!) of gifted programs at many different points. And stop treating gifted education as a reward. If it is seen as an accommodation for kids who need it, and all children are getting an education that matches their needs, then it matters less what the exact percentage of each different group will be.
