Doctor of Education / Department of Educational Leadership / Teresa Miller / The purpose of this research proposal was to investigate school-level factors identified by Marzano (2003) perceived to have contributed positively to student achievement in one charter school. The researcher noted the following issues related to charter schools and student achievement: The data on student achievement were mixed; limited research existed on student achievement using the school -level factors identified by Marzano (2003); limited case studies existed comparing school-level factors and student achievement for charter schools. Using the case study format, the researcher investigated perceptions regarding school-level factors perceived to have increased student achievement in one charter school in Kansas over a five-year period from 2005-2008. The case study was accomplished through the collection, analysis, and interpretation of data from multiple sources to include researcher observations, key informant interviews, and analysis of archival documents.

A case study confirmed the presence of several aspects of the school-level factors of a guaranteed/viable curriculum, challenging goals and effective feedback, parental and community involvement, a safe and orderly environment, and collegiality and professionalism, which were perceived by stakeholders as contributing to increased student achievement over the five-year period of operation.
