Do Girls ‘Earn’ Higher Grades Because of Bias?

Regarding “An Unfair Test for Girls?” (May 11), I am a little tired of reading how “Reliance on standardized test scores as the sole factor in choosing National Merit semifinalists will again cheat girls out of tuition aid they have earned by their superior academic performance.”

Is it just possible that girls “earn” higher grades because of bias on the part of teachers, and objective standardized tests merely bear this out?
