This is one of a series of reports based on an ongoing reality test of systemic evaluation for instructional decision making. This feasibility study is being carried out by the Center for the Study of Evaluation with the Laboratory in School and Community Relations at a suburban Los Angeles high school (called Site A). Viewing a school as a cultural/ecological system, systemic evaluation is a set of principles to guide local development of processes to gather, organize, and utilize information relevant to the needs and values of the system and its members. This paper discusses four key social contextual issues that emerged during the early phases of the Site A project: (1) the current status of the school's Computerized Accountability for Student Achievement (CASA) information management system for counseling and administrative staff; (2) teachers' clinical perspective on information and features of the school's social organization; (3) faculty-district relations as they impinge on the systemic evaluation development; and (4) the nature of the school district's support for the project and what it portends for the future.
