Since at least the 1960s, federal and state policymakers have debated how best to hold public schools accountable for producing graduates who are prepared to fully participate in our democratic society. Since that time, reform efforts have led to Texas' current test-based A-F accountability system. This qualitative case study explored how one Texas school district worked to design and implement an alternative accountability system. A community-based accountability system (CBAS) is created in collaboration with local stakeholders and uses locally developed goals and multiple achievement measures to report student and school performance. A zone of mediation theoretical framework was used to evaluate how the studied district assessed and addressed the community's norms, values, priorities, and goals for public schools. Data were drawn from an analysis of relevant documents, five individual district leader interviews, and a parent and/or community member focus group. These data were analyzed using a combination of a priori and in vivo coding. The six themes that emerged from this analysis were: (a) dissatisfaction with A-F accountability, (b) developing an alternative accountability, (c) collaboration with like-minded districts and leaders, (d) engagement with internal stakeholders; (e) engagement with external stakeholders, and (f) assessing community values and goals for public education. The findings can be viewed as an exemplar for school leaders interested in designing and implementing a CBAS that falls within their community's unique zone of mediation.
