Abstract
This study explored the impact of supervisors' leadership competence on work climate within selected non-government organizations in Lipa City, Batangas. By analyzing data on supervisors' exercise of power styles, efficacy in various functions, and the overall work climate, the study revealed several key findings. The composite mean for the exercise of power styles was 3.75, indicating that supervisors demonstrated effective leadership practices in their work activities. Supervisors exhibited high efficacy in various areas: delivering instruction (mean = 3.74), conducting co-curricular and extra-curricular activities (mean = 3.72), providing guidance and counseling (mean = 3.70), participating in work programs (mean = 3.50), and managing classrooms (mean = 3.87). The status of the work climate was also positive, with a composite mean of 3.56, suggesting a warm and supportive environment, particularly in professional and interpersonal relationships. The study further investigated the effects of power styles, supervisor efficacy, and work climate on clients and subordinates’ academic achievement, finding a composite mean of 3.57, which indicated a significant positive influence. Statistical analysis confirmed a highly significant relationship between clients and subordinates’ academic achievement and the aforementioned variables, with adjusted r square values ranging from 0.9462 to 0.9943, surpassing the critical r value of 0.834 at the 0.01 level. This suggested that supervisors’ leadership styles, efficacy, and the quality of the work climate significantly impacted clients and subordinates' academic success. The null hypothesis related to these variables was rejected, affirming that leadership competence and work environment were crucial factors influencing educational outcomes.
