Consistent with other studies that found bias in schools.
A 2011 study looking at the income disparity between men and women STEM graduates 5 years after graduation found that schools tended to encourage women graduates into lower paying non industry jobs, like elementary and high school teaching.
While encouraging male graduates into higher paying industry jobs that subsequently set them up to get better paying teaching jobs in universities after they gain practical experience the women usually lacked.
When that study compared the income of men and women who made similar job decisions the 5 year incomes were equal with any differences found being performance based. The better employee, male or female, got paid more.
