It employed descriptive comparative design. A total of 159 teachers filled the questionnaires whose reliability was established through pilot study before actual data collection (See appendices). The study concluded that there is significant relationship between participation in decision-making and teachers' commitment. Teachers are committed to the success of their schools and they are emotionally attached to their career. However, teachers' commitment and participation in decision-making was higher in private schools than in public schools. Based on findings, it is recommended that school authorities should maximize participation in decision making in order to raise teachers' commitment. http://pubs.sciepub.com/education/5/7/17/education-5-7-17.pdf participation commitment decision secondary schools Arusha Tanzania
