Just to clarify myself.
The overall study found women were paid significantly less on average. However, they did find opportunities for direct comparison.
As with any group of people, a handful of the women went against the advice of their professors and guidance councilors and went into industry fields after graduation.
Those handful of women are the ones the study looked closer at and found no pay discrepancy that was not accounted for by performance raises. With that decision being equal the women were paid just as well as the men.
There were also a relative few number of men who went straight into teaching after graduation, against the schools advice, that saw the same low salaries as the women encouraged to go into teaching.
When the carrier paths were the same the pay was the same. Bottom line, New male teachers were not paid more than new female teachers. The same in industry.
The pay difference was driven by the carrier path chosen. Which the schools were influencing to the detriment of women.
This study confirms that bias in schools.
