Women's low enrolment in post-school engineering degrees continues to be a problem for engineering faculties and the profession generally. A qualitative interview-based study of Australian women engineers across the range of engineering disciplines showed the relevance of success in math and science at school to their enrolling in engineering at university. However, for a significant number of the women the positive self-image connected with school success was not maintained by their workplace experience. Using a mixed methods approach, further investigations of the attitudes and experiences of working engineers at three large firms suggest that engineering workplaces continue to be uneasy environments for professional women. Particular issues for women working as professional engineers are identified in this paper and some educational strategies are suggested in order to better prepare engineers for an inclusive and participatory professional life.
