Debate about teacher gender balance in primary education is a constant. This debate is fuelled by recommendations to increase recruitment and retainment of males into primary education. In parallel, 10-year trend data indicate a continual decrease in male primary school teachers. Although many factors contribute to the decreasing percentage of male primary teachers, one factor is the gender-related challenges they face in their profession. Previous research has identified some of these challenges; however, a limitation of these claims is contextual and individually bound data derived from qualitative research methods. Large-scale interventions have not been realised as current trends are unable to be generalised to the wider population of male primary teachers. Thus, the aim of this paper is to expand upon previous literature through discussing the development and validation of a scale which quantifies the gender-related challenges faced by male primary teachers.
