This book brings together some of the key researchers and thinkers in the field of lesbian, gay, bisexual, transgender, intersex and/or queer (LGBTIQ+) teacher research. The authors offer international perspectives on the state of play for LGBTIQ+ teachers and engage with some of the key issues that have and continue to shape research. Importantly, this book offers accounts from trans*/non-binary teachers and researchers as well as racialised LGBTIQ+ teachers and researchers--voices that have been absent from the field for too long. The book also offers reflections upon the history of research with LGBTIQ+ teachers and offers an examination of the impact of political and legal changes for LGBTIQ+ people upon teacher identity. The book does not understand the process of change as simple--from intolerance to tolerance--rather, it understands that change is complex, nuanced and experienced differently across and between contexts. As such, it provides readers with a challenge--to accept all that it means to be an LGBTIQ+ educator, including unhappy histories, complex relationships with schools, systemic homophobia and transphobia, and moments of pride and joy. This book was originally published as special issue of the journal Teaching Education.
