With the rising societal awareness of inclusivity and accurate representation in films and other forms of media, it has become increasingly important that cultural and sexual diversity are not neglected in the material used in education, especially in English Language Teaching (ELT) where the chosen material is supposed to represent the whole English-speaking world. Previous research often focuses on the difference between national and international textbooks and compares the results between them. While some studies have focused on either cultural or sexual diversity, none have included both and there are not many studies that focus on Swedish ELT. Four textbooks were analysed in this study; Short Cuts to English 1 (2001), Streams 1 (2004), Pick & Mix 1 (2013), and Blueprint A (2017). Inclusivity and representation of cultural and sexual diversity were analysed using three models. Analytical methods focused on the aesthetic and sociological senses of culture, the circles of countries, and the levels of heteronormativity in the textbooks. Ourfindings show that there is a lack of inclusivity and representation of sexualities other than heterosexuality, and that even for culture there is a lack of inclusivity outside of English-speaking countries. Results indicate that the four textbooks used in this study did not display a high level of inclusivity regarding sexual diversity. Although still small, levels of inclusivity and representation of different cultures were greater.
