This qualitative case study examines academic performance effectiveness (or lack of effectiveness) of a charter school based on the perceptions of the administrator and teachers. This study explores what they perceived to be effective/ineffective, the reasons for this effectiveness/ineffectiveness, and the solutions to any identified challenges/problems at their charter school as they relate to students' academic performance. The participants in the study were from one charter school in a charter school system in North Central Texas. The study utilized surveys and interviews as sources of data that revealed administrator and teacher perception of what they considered to be the strengths and weaknesses of the school, factors accounting for the strengths and weaknesses, and possible solutions to the weaknesses of their charter school as related to students' academic performance. Five perceived strengths were identified to be instruction, curriculum, personnel, mission statement, and parent involvement. Likewise, three perceived weaknesses were identified to be instruction, curriculum, and parent involvement. Recommendations of the study for practitioners included recruitment and employment of preservice teachers from colleges and universities, partnering with alternative certification programs, creating a program of professional development, creating professional learning communities, creating a parent committee, and partnering with local agencies and community businesses. Implications for future research included similar analysis of schools within the same charter school system, analysis of a charter school within another charter school district and replicating this study with the addition of parents.
