Catholic schools have faced enrollment challenges for at least two decades. The staggering numbers of Catholic school closures should compel all stakeholders to reflect on the traditional model of Catholic schools and consider what alternative models could more effectively carry out the mission of the Church. Alternative school models, such as microschools, offer Catholic schools a promising solution and opportunity to continue their mission. Microschools utilize a scaled model of operations, including multiage instruction, and improve operational vitality. This project investigated microschools as a bold and innovative solution needed to keep doors open in Catholic schools and continue to provide robust Catholic education in struggling parishes and communities. To better understand the perceptions of Catholic school leaders who have navigated the transition of a parish school to a microschool, the team conducted a mixed-method study to identify leaders who took bold initiative to sustain Catholic education in their community. The study revealed that, during a time of transition, leaders benefited from leadership formation and support as well as strong communication and intentionality. Their Catholic microschools experienced improved operational vitality, higher academic achievement and stronger Catholic identity.
