Abstract
Duckworth (2015) defines grit as a non-cognitive variable determinant of success. In various fields, including education, grit has been linked to long-term success and efficacy. This study explores the moderating role of age and career stage on the relationship between grit and work engagement among public school teachers in Valenzuela City. Using a cross-sectional explanatory research design, the study examines relationships between grit and work engagement while assessing whether age and career stages influence these dynamics. Results suggest that older employees experience higher levels of engagement and that the career stage significantly moderates the relationship between grit and engagement.
