2Gen convenings have the potential to create change for whole systems and the lives of the families they serve. This planning guide is the first step. Having planned and supported more than 100 2Gen convenings, Ascend has cultivated a depth of knowledge for the practical elements and nuanced factors that result in successful convenings. This toolkit considers concrete examples from many 2Gen convenings and illuminates the lessons learned and best practices developed with the aim to at once maximize the impact and minimize any inefficiency in developing and hosting convenings. Our hope is that the toolkit will support 2Gen practitioners, policymakers, researchers, and philanthropists across the country in more effective convening outreach, partnership, and impact.
