League of VetaHumanz uses a nationwide network of university-community partnerships to provide veterinary STEM learning experiences for children who are more likely to lack access to enriching, supplemental educational opportunities due to systemic barriers based on their race, ethnicity, or socioeconomic status. To include participation beyond in-person programming, SuperPower Packs, self-guided, learning experiences, were developed. Leveraging social cognitive career theory and the "Batman Effect," SuperPower Packs are designed to build self-efficacy, and seed STEM and veterinary science career aspirations by engaging children in STEM learning through connections with a veterinary role model. Four SuperPower Packs were developed. Beginning in the fall of 2021, for 17 months, 16,655 SuperPower Packs were distributed to children in 23 states. A small portion of children who received the game (3.8%, N = 614, 6-12 years old) returned evaluation surveys that measured activity engagement, likelihood of role model identification and demographics. Participants indicated variation in their experiences, but mean scale scores show desirable perceptions of engagement (M[subscript Range] = 2.38-2.90/3) and role model identification (M[subscript Range] = 2.15-2.94/3). These positive learning and role model experiences help set the stage to encourage youth to pursue similar learning and career opportunities in the future.
