We analyzed how teacher perception of job demands and job resources in the school environment were related to teacher well-being, engagement and motivation to leave the teaching profession. Participants were 760 Norwegian teachers in grade 1-10. Data were analyzed by means of confirmatory factor analysis and SEM analysis. A second order job demand variable strongly predicted lower teacher well-being, whereas job resources more moderately predicted higher well-being. Teacher well-being was in turn predictive of higher engagement and lower motivation to leave the profession. Analysis of primary factors showed that time pressure was the strongest predictor of teacher well-being.
