In UK also, women teachers predominate at Yrs Reception - 7 (called primary here) and this is sometimes used as an explanation of girl students superior acheivements at School leaving level, aged 16+ (called GCSE in UK).
However, I feel it is difficult to regard girls' dominance of exam results as a "problem" since i remember the differential hurdles presented by (11 year olds) grammar school entrance and (18 year olds) medical school entrance where girls/women had to achieve higher than their male counterparts. Now that these gender hurdles have been removed, women outnumber men. This provokes some interesting reactions, see http://society.guardian.co.uk/NHSstaff/story/0,7991,749021,00.html
e.g. "Michael Crowe, a GP from Leicester, said when he was a medical student there had been eight men to one woman, but now the "pendulum has swung too far in the other direction".
He said: "There is a problem brewing and it needs correcting.""
I am not sure of what we can learn from this but, as a woman, I do feel that the issue of gender balance in professions is a complex one that needs a rich understanding. I also recall that male dominance of professions was rarely regarded as a "problem".
