Across the world, women experience violations to their reproductive health and threats to their educational aspirations that limit their achievement. Reproductive health and education are examples of women’s human rights that are connected by systemic gender inequalities that lead millions of women to experience discrimination and stereotyping that threaten these basic rights. The current study uses a reproductive justice framework to examine how a community‐based organization led by a group of women in rural Nicaragua challenges gendered psychosocial processes related to women’s rights violations. In partnership with a grassroots local organization, we used structural equation modeling to demonstrate, in a sample of almost 300 women, that organizational participation was positively related to women’s reproductive decision‐making and educational aspiration, in part due to relationships with women’s self‐esteem and sense of powerlessness in sociopolitical matters. Given the persistent role of gendered inequities in the reproductive decision‐making and educational aspirations of girls and women, considering the social‐structural contexts that enable or limit rights is imperative to creating viable routes to gender justice.
