For the people behind the Lumina Foundation for Education, the term "network" has particular meaning. In fact, largely as a result of their work in a national college awareness and action campaign called KnowHow2GO, they have come to define networks in a specific way--and they ask their KnowHow2GO grantees and partners to form networks that fit that definition. For them, a strong and sustainable network for increasing college access and success must be built on five dimensions: (1) An infrastructure that enables members to identify and achieve a shared purpose; (2) Service system cohesion, improvement and sustainability; (3) Data-based decision making about priorities, policies and practices; (4) Expertise in college access and success issues and advocacy for supportive public policies; and (5) Creation and dissemination of knowledge within the network and beyond. Already, such networks are leading the KnowHow2GO effort in 16 states. The KnowHow2GO campaign isn't the only example of networks in action. In fact, the principles of effective networks--principles articulated eloquently by Paul Vandeventer, president and CEO of Community Partners, in his book "Networks that Work"--are being embraced by any number of Lumina grantees and partner organizations. This issue of "Lumina Foundation Lessons" magazine highlights three such organizations, all of which are working tirelessly to promote college success among low-income and minority students. In this issue of Lessons, readers will learn about the LIFETIME (Low-Income Families' Empowerment through Education) program, which assists welfare mothers in their quest for college attainment in California. Readers will read about the Providence, Rhode Island-based organization What Kids Can Do, which empowers students to tell their own stories as a means of boosting postsecondary success. Finally, in Florida, readers will meet the organizers--and especially the students--who are involved in the policy-advocacy group ENLACE (ENgaging Latino, African-American and other Communities for Education).
