This guide is designed to help educators make good decisions about comprehensive school reform (CSR). Since CSR takes different forms in different schools, the booklet should help schools craft a unique plan that builds on unique strengths. It emphasizes the importance of choosing carefully one or more research-based CSR models to serve as the centerpiece for reform and then developing a common vision of change. Some 17 models are offered, and, although they might not meet every need of a school's CSR approach, they can provide essential guidance. Since choosing a model is essential to the process, the text lists nine criteria to consider when selecting a plan, which is followed by four basic steps for decision-making: (1) laying the groundwork; (2) evaluating the current situation; (3) profiling an ideal approach; and (4) deciding on a model. These protocols should help educators assess student learning and accomplishments, create a profile of an ideal CSR approach, and conduct research on a variety of CSR models. The bulk of the guide is contained in eight appendices that feature a self-evaluation tool, a summary of a self-evaluation, a profiling tool, a student-population chart, a sample research grid, and a list of resources.
