Contextual elements at school playgrounds compromise the right to play.An occupation-based social transformation project to foster occupational justice in play at a school playground was conducted. To better understand barriers to and facilitators of children's participation in occupations at the school playground to co-create actions that enable play. Design:A participatory methodology-Photovoice-was used. The research consisted of four phases: involving the community in the research design, community-led data generation and analysis, discussion of findings to increase the community's awareness, and a community agenda for changing the playground. Public primary school playground in northwest Spain. All children (n = 450, ages 3-12 yr), families (n = 12), and teachers (n = 15) participated. A thematic analysis of visual, textual, and oral material was conducted, including member checking. Results: The study revealed several barriers toplay, including the short recess duration, poorfloor (surface) conditions, jail-like atmosphere, andviolence. However, participants identified an ad hoclending games systemandplayground muralsadvocating for children's rights as facilitators. These findings have direct implications for improving the play environment. Conflicting priorities between children's and adults' desires and needs for the playground were unveiled, displaying the relevance of invisible contexts (i.e., social or institutional contexts) in shaping play opportunities. A critical occupational stance combined with a participatory and playful methodology generated space to unveil these conflicting priorities, reconcile agendas, raise awareness, and propose collective actions to transform the playground. Plain-Language Summary: Playing is fundamental to children's development and inclusion. This study focused on making school playgrounds better places for kids to play. Researchers found that things such as short playtimes, bad playground conditions, and violence made it tough for kids to enjoy playing, but they also discovered some good things, such as a system for borrowing games and colorfulmurals promoting children' rights. These findings show that changing the playground's physical and social environment can make a big difference for kids. By listening to kids and working together, adults and children can create playgrounds where all kids can play meaningfully and safely. Occupational therapists can promote such processes.
