Parental support or resistance has been widely recognised as an important factor that enables or constrains the implementation of quality Relationships and Sexuality Education (RSE). This paper analyses parental experiences of involvement and engagement with Gender Equality Matters (GEM), an educational programme focused on raising awareness, building confidence and enhancing capacity levels among children to tackle gender inequality and promote LGBTQI inclusion. The paper focuses on qualitative data from participating parents in the Irish primary school context. Pre- and post-questionnaires (n = 162) and semi-structured interviews (n = 3) were utilised to gain insight into the parents' experience of participating in GEM. Using thematic analysis, the analysis explores three themes: 1) positive parental partnerships; 2) naturalistic at-home conversations; and 3) resistance and disengagement. The study highlights the key role of parental partnerships with school curricula, whilst critically reflecting on potential sites for resistance and providing a successful model for future educational programmes to adopt.
