For the past fifty years, there has been a gap in the educational achievement of males and females in the United States, but which gender has been disadvantaged has fluctuated over the years. In the 1970s and 1980s, data showed girls trailing behind boys in a variety of academic performance measures, specifically in test scores in math and science.
Data in the last twenty years shows the general trend of girls outperforming boys in academic achievement in terms of class grades across all subjects and college graduation rates, but boys scoring higher on standardized tests and being better represented in the higher-paying and more prestigious STEM fields (science, technology, engineering, and math).
