This study aims to determine the views of administrators working at private schools in Kahramanmaras and Gaziantep on evaluating teacher's performance and to make some recommendations for an effective and sufficient teacher evaluation accordingly. This study explores questions such as what administrators think about implementing the evaluation results, whether there should be an evaluation system that diffrentiates by teacher competencies or not and how teacher's performance evaluation systems contribute to teacher's professional development. The data were gathered through semi-structred interview forms and analysed through the content analysis method.
