This study compared survey responses of teachers from a reform-based programme focused on promoting inclusion-based classrooms, namely Project WINS (Winning Ideas Network for Schools) schools, with teachers from non-Project WINS schools with regard to their attitude about inclusion in the classroom. Surprisingly, the results of this study revealed no differences between the two groups of teachers on most facets of inclusion. The one significant difference found a greater preference for inclusion by non-Project WINS teachers with regard to classroom climate. The study also revealed a higher preference for inclusion for teachers with higher self-reported expertise in special education regardless of what group the teacher was surveyed from. Findings from this study indicate the need for further research and improvements in training methods for Project WINS and similar programmes that attempt to change teachers' attitudes towards inclusion as an important first step in improving practice in inclusion-based classrooms. As the movement for more inclusion in schools increases, administrators, special educators and teachers are caught in the midst of the tide. Proponents of inclusion believe change is needed now, but those not in favour of such changes recommend not implementing inclusion without further research (Snyder, 1999). In addition, schools need assistance in developing and implementing policies and practices that will lead to an effective inclusion experience for all parties involved (Johnson, 2000). The primary purpose of this study was to further this research by examining attitudes related to inclusion of teachers participating in a programme implemented in middle schools with the explicit goal of fostering effective inclusion-based classrooms. Second, we tested the relationship between perceived expertise in special education and attitudes towards inclusion. Below we briefly describe some of the factors that research has shown to influence teachers' level of acceptance of inclusion-based classrooms.
