The Community Science Workshops (CSWs)--with funding from the S.D. Bechtel, Jr. Foundation, and the Gordon and Betty Moore Foundation--created a network among the CSW sites in California. The goals of the CSW Network project have been to improve programs, build capacity throughout the Network, and establish new sites. Inverness Research has been the external evaluator for the Network project, continuing a relationship of evaluating the Community Science Workshops that began in 1995. The evaluation effort of Inverness Research has focused on documenting and portraying the growth and development of both the Network and individual sites, through regular participation in meetings and retreats, ongoing interviews with Network staff, site directors and board members, and visits to sites that included observations of programs, interviews with youth and families, and interviews with workshop staff. Network staff worked closely with Inverness Research on developing and piloting tools for ongoing data collection--student surveys, program overview and learning environment surveys, and a family interview protocol. The key evaluation questions that guided this work over the past several years include the following: (1) How has the CSW Network developed and evolved?; (2) How would the health and development of the CSW Network be characterized as a networked organization?; (3) In what ways and to what extent has the Network helped create or increase capacity at the various workshop sites?; (4) In what ways and to what extent has that increased capacity bolstered programming at the sites?; and (5) What is the impact of the bolstered programming on participating youth and families? This report contains the case studies of the individual Community Science Workshop (CSW) sites that are discussed in "The Community Science Workshop Network Story: Becoming a Networked Organization" (available at http://inverness-research.org/reports/2014-02_Rpt-CSW-NetworkFinalRpt-Appdx_032414.pdf.) The case studies included in this report are the following: (1) Excelsior Case Study; (2) Fresno Case Study; (3) Greenfield Case Study; (4) Mission Case Study; (5) Oakland Case Study; and (6) Watsonville Case Study. Individual studies contain references. [For "The Community Science Workshop Network Story: Becoming a Networked Organization," see ED558175.]
