The main purpose of the book is to explore whether native speakerism has an influence on Polish language schools, using the explanatory mixed-methods design. The findings show that the ideology is present in Poland, but it is manifested in complex and subtle ways. Most prominent findings indicate a wage gap between teachers considered native speakers and their Polish counterparts, and the discrepancy between the levels of education required of the two groups, with native speakers often being employed without necessary qualifications. Finally, the findings suggest that Polish teacher education programmes should expose budding teachers to relevant literature regarding native speakerism and other issues related to native and non-native speaker status so that they can critically examine them.
