Christian schools face both opportunity and challenge. The opportunity is to deliver a distinct, Christ-centered, educational experience in today's culture. The challenge is that after decades of tremendous growth, many evangelical Christian schools face decline and closure due to economic pressures and the associated costs of rising expectations. Though evangelical schools tend to operate independently, circumstances are motivating schools to forgo independence in exchange for innovative collaborative solutions that offer strengthened learning environments and sustainable models. This study includes a biblical theological review of the principle of collaboration as demonstrated by biblical characters. Also incorporated is research on the relevant, available literature within the public and private school sectors. The project includes interviews of school leaders with personal experience or knowledgeable insights into collaborative solutions as well as a case study from the first-hand account of the author who helped to lead a three-way school merger during the writing of this project. The field project is a guidebook of collaboration resources and best-practices. The guidebook shares the interviews and case study as practical application examples and draws on the research to provide historical overview, values, benefits, and liabilities of collaborations, as well as key factors, leadership principles, and decision-making areas to review when considering collaborations. The goal is to add research to the growing need for private Christian school collaborative solutions. [The dissertation citations contained here are published with the permission of ProQuest LLC.
