The purpose of this research was to examine task-oriented and socially-oriented leadership patterns in public secondary school directors in Bangkok Metropolis, Thailand. This analysis was conducted to determine if leadership orientation as well as gender-based leadership behaviours were related to school climate. Surveys, questionnaires and interviews were used to obtain data from directors and teachers. Utilisation of cross case study research analysis and qualitative data indicated that gender based leadership traits, rather than administrator gender, appeared to be associated with school climate. This research suggests that an effective instructional leader, at the secondary level, is fundamental to the teaching and learning process. Quality educational leadership promotes positive school climates for teacher satisfaction and student achievement. Research studies have focused upon possible determinants for school climates.
