The document discusses the influence of different leadership styles of principals on student academic achievement. It describes the autocratic, laissez-faire, and democratic leadership styles. The autocratic style negatively impacts achievement because it is harshly detested by teachers and students. The laissez-faire style has little influence as tasks are left to teachers without follow up. In contrast, the democratic style positively influences achievement as it motivates teachers through support, teamwork and participation in decision making.
