This study investigates the relationship between teacher effectiveness, job satisfaction, and occupational stress among secondary school teachers. The findings reveal that the majority of secondary school teachers exhibit moderate levels of teacher effectiveness (62.08%), job satisfaction (90.5%), and occupational stress (76.4%). Approximately 15 to 16% of teachers display high levels of teacher effectiveness (15.9%), job satisfaction (14.9%), and occupational stress (16.3%), while 13 to 15% demonstrate low levels of these variables (teacher effectiveness - 13.3%, job satisfaction - 15.1%, occupational stress - 15.3%). Moreover, gender does not appear to influence teacher effectiveness, job satisfaction, or occupational stress significantly. However, there is a positive correlation observed between job satisfaction and occupational stress. These findings shed light on the complex interplay between teacher effectiveness, job satisfaction, and occupational stress, highlighting potential areas for intervention and support within secondary school settings.
