It has been more than 20 years since the publication of Community Programs to Promote Youth Development (a.k.a. the Blue Book). Since then, other seminal studies have explored, described, and elevated the youth development field and out-of-school-time (OST) programs. My professional career trajectory has in part followed this history, starting out as a participant in a community drop-in center in the 1980s to my role as a researcher in the youth development field to now having the honor of chairing this esteemed committee. It has been more than 20 years since I attended my first national field conference and recognized that my job in a local community-based program in Chicago was a part of a much larger national movement. I acknowledge and celebrate how much has changed in those 20-plus years.
The youth development field has seen the evolution of intermediaries and other cross-sector partnerships in support of strong programs and program access, and the rise of the quality movement and related measures, standards, and practices. As a result, we have seen the rise of a stronger, more unified workforce and aligned supports, despite the ever-complicated funding landscape. In this study, the committee endeavored to explore, describe, and elevate the landscape, evidence, and narratives that depict today’s OST experience.
Program participation has increased, but not for all children and youth. There remains a strong unmet demand for programs from families with marginalized backgrounds, for those in rural settings, and lower participation overall among teens. Much of the early research on youth development, including the Blue Book, was focused on programs for teens. Yet, today teens make up, as far as we know, the smallest portion of program
participants. Did progress in the field (the idea that structure and regular participation are a priority) make programs less appropriate and appealing for teens today? Access to programs for teens is one of the unfulfilled promises of the youth development field at a time when it can be most beneficial. Recently, the surgeon general informed us that youth mental health is in a state of crisis. More young people today are disconnected from school or work, and we know that this only scratches the surface of what teens are going through as they weather today’s sociopolitical climate with heightened access to a plethora of information and conflict. The committee describes the landscape of program participation and demand; we need to know more about the children and youth who are not showing up for programs so we can do more to promote access to high-quality opportunities for all.
We have weathered high-stakes evaluation with often misaligned outcomes during an era of accountability and then celebrated the recognition of the role of the field in supporting participants in their learning and development. . . while still scurrying to measure how well programs were supporting the slipperiest of outcomes. We know more about what works in some programs for some participants, but because of the diversity of field-driven offerings, we do not quite have our arms around a shared logic model for programs, nonetheless a shared nomenclature. And that may be the crux of youth development: in our celebration of the grassroots, culturally responsive, and locally derived programs, we are hesitant to come to agreement on who we are and what we do to a point where we can then concretely understand how we are doing on behalf of the children, youth, families, and communities we serve.
On the other hand, families with means to pay for services and programs (care, arts, sports, and clubs) simply agree that it is a good idea for children and youth to be cared for, form positive relationships, learn something new, have fun, prepare for their future, and spark their interests. Is it necessary for us to dissect subsidized programs differently, and to what end, and at whose expense? It is certainly reasonable to assess how well public dollars are spent, but to do that we can look toward implementation quality and the diversity and richness of program offerings and let programs off the hook for moving the needle on everything. I commend the committee for grappling with the basis of evidence, and it is clear that while we need agreed-upon evidence on the relationship between systems-level supports and program implementation, and between program experiences and youth outcomes to understand what works for whom, we need to take the onus off individual programs to repeatedly prove their worth. If the committee’s microcosm of an experience in exploring the plethora of varied evidence is an indicator of the wide-ranging discourse needed to come to consensus on the basis of evidence in OST, then we have important work to do on a shared research agenda.
Intermediaries and other cross-sector partnerships built to foster cross-sector alignment were not new 20-plus years ago but were recognized and invested in as potential backbone entities for the youth development field in the absence of other public, more formal mechanisms. They remain the invisible and sometimes unsung hero in the field holding the reigns of quality, professional development, funding, and measurement for cadres of programs in a locale. Yet these intermediaries are subject to tenuous funding stability, and often their success hinges on leadership connections and political prowess—it is scary for a backbone to be strong on flimsy funding. The committee describes the many roles intermediaries play in the field, and we need to ensure we can move to stable support for intermediaries to sustain their integral role.
Trends in professional learning, possibilities for a shared labor category, definitions of core competencies, and general recognition of the importance of the youth development workforce have come a long way in the last 20 years, while some challenges remain the same, particularly for early career entrants and part-time workers. Youth development professionals report they enter and stay in the field because of their passion and sense of mission, yet passion and mission are not enough to recruit and sustain a workforce to meet the unmet demands for programs. Today, youth work practitioner pay and benefits is more on par with other service professionals than it may have been in the past, especially for those in leadership; yet service professionals (e.g., childcare workers) as a whole do not make a livable wage. The committee describes the current landscape of youth development professional pathways based on current data, which should be updated regularly so we can continue to inform policy on this essential workforce.
Support for programs and funding has grown, but not on par with demand or inflation. For a field so fundamental to child and youth experience and supportive of families, its existence remains precarious and, to be a little dramatic, at the whim of one foundation board meeting or election. Despite some hallmark federal funding and decades-long investments by a small group of foundations, funding remains precarious for something that is in the fabric of youth experience. The youth development field can and should be coordinated centrally and woven into the nation’s safety net, yet it remains supported in a disjointed manner with unheralded champions to manage coordination at all levels. The committee describes this complex policy and funding landscape at every level with recommendations to streamline processes to alleviate the onus on individual programs or systems.
It was an honor and a privilege to work shoulder to shoulder with committee members; our stellar National Academies team, including the unflappable Priyanka Nalamada; and our contributors to present the landscape of evidence in OST. In many ways, we have made great strides from
defining the field to defining what works in the field to support children, youth, and their families on their pathway to thriving. But there is more to do. Based on our experience with the many individuals on the committee, our contributors, and those experts who we heard from at public sessions, I am confident we have the right champions, researchers, and policymakers for the job.
On behalf of the National Academies and its Board on Children, Youth, and Families, we thank the Wallace Foundation for sponsoring this study and share great hopes that this report will inform momentum in the field as did the Blue Book more than 20 years ago.
