A scoping review on the psychometric properties of the teacher efficacy for inclusive practices (TEIP) scale

Teachers' self-efficacy for inclusion is emphasized as necessary for enabling inclusive education. One instrument developed for measuring teacher self-efficacy for inclusion is the Teacher Efficacy for Inclusion Practice-scale (TEIP) (Sharma, U., Loreman, T., & Forlin, C. (2012). Measuring teacher efficacy to implement inclusive practices. Journal of Research in Special Educational Needs, 12(1), 12-21). The present study aimed to identify and summarize the empirical literature on structural validation and reliability of the TEIP scale. A scoping review of 15 peer-review articles was conducted. The three subscales found in the original TEIP scale were confirmed. However, there is support for two subscales. The TEIP is also reported to be a construct without multidimensional constructs of teacher-self efficacy. Although the items worked differently in different samples, the internal consistency was generally sufficient or good. Our findings indicate that the TEIP is not yet a scale fit for comparisons between populations and contexts, reflecting the multifaceted nature of the concept of both inclusion and teacher self-efficacy.
