The study investigated the influence of leadership style on organizational productivity for sustainable national development. Three research questions and three null hypotheses guided the study. Data were collected from10 heads of departments and 269 lecturers from the department of educational management in federal and state universities in South–East, Nigeria who served as the population. The size of the population was manageable so there was no need for sampling. The instrument used for data collection was a structured questionnaire of 24 items. Using mean and standard deviation, the research questions were analyzed, while the hypotheses were tested using chi-square statistics at 0.05 level of significance. The findings revealed among others that leadership style significantly influenced the quality of school turnout for sustainable national development and that democratic leadership style significantly influenced service delivery by the lecturers with regards to carrying out delegated duties, taking part in decision making and instructional management. It was thus recommended that leaders should be more democratic and dynamic in their leadership styles for increased productivity and qualitative output towards sustainable national development.
