Many intervention programmes to increase the number of women in theInformation and Communications Technology (ICT) profession have been implemented over the last twenty years. Detailed evaluations help us to determine the effectiveness of these programmes yet few comprehensive evaluations appear in the literature.The research reported here describes an investigation of the evaluation of the intervention programmes focusing on increasing the enrolment and retention of females in ICT in Australia. This paper describes an empirical study which explores how evaluation has been and might be conducted and concludes with guidelines for evaluation for those developing programmes for increasing the participation of women in ICT.The guidelines encourage evaluation to be considered early, highlight the importance of establishing objective outcomes and promote the publication of results to build knowledge for those planning programmes in the future. Further, the developed guidelines could adapted and used with other ICT intervention programs.
