The purpose of this study was to assess the practices and challenges of school level strategic plan development and implementation in secondary schools Special Zone of Surrounding Finfinne. In so doing, basic questions related to priority areas in planning, stakeholders involvement in planning, monitoring and evaluation of plan implementation and the challenges encountered were raised to guide the study. The researcher used descriptive survey design and both qualitative and quantitative research approach in an attempt to answer the basic questions. Both primary and secondary sources of data were used to obtain appropriate data. Primary data were collected from 79 randomly selected teachers, and 12 school principals/ vice principals and 7 WEO experts who were selected using availability sampling techniques. Data from teachers were collected using questionnaire while interview was used to school principals and planners.rnSome of the major findings were: the practices of identifying priority areas to develop school plan was not conducted through evidence based assessment of the existing situation and self-assessment before beginning to decide on school improvement goals, to plan and implement properly. The participation of stakeholders in developing and implementing school level plan was not up to the expectation and lack coordination and integration. The level of monitoring and evaluation was low, whether the school level school plans are implemented as they are intended. Furthermore, the reward system was not enough. Therefore, it is concluded that the above mentioned problems are major factors that hampered school planning and implementation activities of school level plans. Hence, it is suggested that the coordinated efforts of Regional Education bureau (REB), WEO/TEO and schools is needed to minimize these problems at their early stage and ensure the implementation of school level plans by giving continuous training, technical support and reward best performing stakeholders and school community.
