The participation of stakeholders in developing and implementing school level strategic plan was not up to the expectation and lack coordination and integration. The level of monitoring and evaluation was low, whether the school level strategic plans are implemented as they are intended. Furthermore, the reward system of stakeholders both at school and WEO/TEO was not enough.
