The Orange County Public Schools' (OCPS) external analysis model gathered and analyzed information from external sources to determine the impact of external events, trends, and issues on the schools for years to come. The OCPS model analyzed population growth, political decision making, the decline of federal funding assistance, change in the school population composition, change in family structures, business trends, and others. The model had six phases: (1) environmental scanning; (2) data organization, storage, and retrieval; (3) data evaluation, analysis, and usage; (4) development of assumptions about the future; (5) development of implications for OCPS; and (6) environmental monitoring.
