Do teachers with similar experience and age but different genders earn the same income? This study investigates the income of teachers relative to their age, education, experience, race and gender. Studies have shown that inequality in the gender wage gap is a trend which closed for almost two decades, but has recently widened again. This study identifies a specific line of work where injustice can be seen and aims to bring this knowledge to light. The Current Population Survey (CPS) data set from 2005-2009 will be used for this study. This study finds empirical evidence that gender differences do in fact have a significant impact on income in the teaching profession, reflecting inequalities in the workplace. This study also finds that the gender based wage gap grows for the postsecondary teaching level, and narrows for preschool and kindergarten teachers.
