Title I schools that serve a large population of low-income students often view families through the lens of an outdated paradigm of family engagement in education, assuming parents are mostly uneducated, ill informed, and much in need of training and support to be good parents. "Comunitario" projects in the Rio Grande Valley of south Texas model a new kind of family engagement in education: intergenerational family leadership, or "liderazgo familiar intergeneracional," which values the participation and collaboration of parents, community members, and youth. The locus is the family and, therefore, requires personal outreach, home visits, multiple settings for meetings, and seeking creative ways to inform families who, because of work and other circumstances, are not able to attend an evening meeting on campus. In this article, the authors focus on the ways that intergenerational family leadership recognizes the contributions of youth in family engagement, offering opportunities for them to serve as mentors to their peers as well as to adults in the community. They explore the ways that investing in true family leadership in this way has allowed them to scale up the "comunitario" approach as they have implemented the federal Investing in Innovation (i3) grant.
