This dissertation focuses on entrepreneurial and business performance indicators as determinants of Arizona charter schools' quality. The study utilizes a mixed-method inquiry with focus on qualitative research, exploration, and implementation studies. It draws data from surveys with charter operators performed by Education Team Partners (ETP). All survey results are drawn from the ETP database. The study reviews the genesis and evolution of charter schools. It reviews the social agreement within the context of public policy analysis, and the public-private partnership nature within the context of entrepreneurship and business management. It attempts to develop a research-based foundation for future action research to complement the newly introduced performance management plan (PMP) measurement and evaluation system in Arizona. The research includes four group indicators for measuring charter schools' business productivity and performance. They are studied in relation to three groups of indicators for measuring charter schools' quality. The case studies include two existing and two future charter schools. Study results indicate that all participating charter operators confirm the significance of the liquidity ratio in relation to any aspect of charter school quality covered in this study. The participants indicated a strong relationship between the capacities of their schools to utilize external resources and all indicators of charter school quality. This study draws two important conclusions. First, charter schools are business organizations, despite the fact that they receive public funds. Operationally, they differ substantially from district schools and government agencies and depend on market forces. Second, charter schools cannot survive inefficient management practices, as market forces tend to drive them out of business, regardless of academic success and student achievement levels. The intended implications from this study include: first, increased awareness about the importance of understanding business indicators in relation to charter school quality; second, the need for more research associated with the business and finance components of charter schools. As the body of collective knowledge about charter schools expands, the relationship between various business indicators to measures of quality should be routinely studied within larger populations, which may allow for an improved measurement system and applications of advanced statistical methods.
