This paper describes the development of an improved scale for measuring sentiments, attitudes and concerns about inclusive education in pre-service teachers based on an examination of data gathered from 996 pre-service teachers from five tertiary institutions using a modified version of the Interactions with People with Disabilities scale (Forlin, Jobling & Carroll, 2001; Gething, 1991, 1994), the Concerns about Inclusive Education Scale (Sharma & Desai, 2002), and the Attitudes Toward Inclusive Education Scale (Wilczenski, 1992, 1995). Based on the results of principal component analyses, conceptual judgments made by the research team, and a critique of content and format from an "expert group", a new scale, the Sentiments, Attitudes and Concerns about Inclusive Education scale (SACIE), is developed. The rationale behind the development of the scale is discussed. (Contains 8 tables.)
