Until recently, many early childhood educators, particularly those in nontraditional preschool spaces, leaned on a color-evasive approach to their work, largely ignoring systemic racism and bias, claiming love and acceptance of all children in their care. While well-intentioned, these practices left young children to construct their own understandings of issues like race, gender, sexuality, and ability, often solidifying the racist and biased ideological messages from popular society. Since 2020, however, a year marked by political division, a global pandemic, and a public reckoning over systemic racism, early childhood educators have been reexamining their practices. Armed with research on young children's racial awareness and buoyed by support from the National Association for the Education of Young Children, preschool programs around the country began looking for ways to implement equity-based teaching practices with young children. This participatory case study follows the administrators and teachers of one preschool program in central North Carolina as they worked to implement antibias/antiracist (ABAR) teaching practices in their play-based, community-centered early childhood classrooms. Relying on data from classroom observations, follow-up interviews, and staff meetings, the study examines what it means to implement ABAR teaching practices in nontraditional preschool spaces, with a specific focus on the supports and barriers the teachers encountered in this process. The findings of our study highlight the multiple administrative and collegial supports teachers feel in their ABAR work with young children: administrative policies, professional development, a feeling of safety and security, and personal empowerment and wellbeing. The study also found that implementing ABAR teaching practices requires attention and intention on the part of educators and the community as a whole. This intentionality is best supported through a community of like-minded educators and families with shared values and commitments to liberatory preschooling. Early childhood education is a field that is often overlooked by educational researchers. And because ABAR is a new approach in education as a whole, there has been very little academic research into ABAR in preschools. This study begins to fill that gap.
