Thirty pre-service teachers took part in a nine-week university course focussed on the benefits of inclusive education and the techniques needed to successfully implement it. The Teachers' Attitudes Toward Inclusion Scale (TATIS), Concerns about Inclusive Education Scale (CIES), and Teacher's Efficacy in Implementing Inclusive Practices (TEIP) were administered prior to and following the university course. Paired sample t-tests revealed that participants' attitudes and efficacy increased significantly following the course while their concerns decreased significantly. Mixed design ANOVAs revealed that pre-service teachers without past experience of teaching students with disabilities had the largest improvement in attitudes. Pre-service teachers who were not acquainted with a person with a disability had significantly larger decreases in concern level and increases in efficacy level than those who were acquainted with a person with a disability. These results are discussed and implications for future research outlined.
