The purpose of this paper was to posit and test hypotheses concerned with relationships between teachers’ demographics, locus of control and career stages. A sample consisting of 416 Australian non-executive high school teachers was gathered from 40 randomly selected high schools. Multilevel regression analysis reflecting the nested nature of the sample of teachers within schools, and allowing for testing for school effects, was employed. The paper finds that significant gender and years of teaching experience differences were identified for a number of career stages. There were positive relationships between years of teaching experience and later career stages. A number of multilevel models relating locus of control and demographic variables to career stage were developed and are reported.
