Our multi-disciplinary research team explored the experiences and concerns of Latino/a students and their parents related to being welcomed and included in Catholic high schools in a United States diocese. We collected both qualitative and quantitative data in order to create a fuller picture of Latino/a experiences in these high schools. We make recommendations based on our findings to advance the scholarship on best practices for including students of new demographic groups in Catholic high schools with a specific focus on welcoming and including Latino and Latina students in Catholic high schools.
