Using discriminant analysis, this study attempts to construct profiles of two types of teachers: those with a low level of job satisfaction and those with a high level of job satisfaction. In addition to their background and demographic characteristics, teachers’ perceptions of their occupation and of their principals’ leadership styles (transformational or transactional) are examined as predic...
