This article employs the notions of exclusivism and inclusivism to categorise the responses of prospective Islamic religion teachers towards various Islamic religious sects. Despite the prevalent criticism surrounding the perceived oversimplification and a lack of insight provided by the two typologies, we have found them to be valuable tools for elucidating the phenomena under investigation. Quantitative data were collected from 154 respondents using questionnaires containing multiple-choice questions. Data frequency, cross-tabulation and gamma values are statistical techniques employed to analyse and characterise (...) data and ascertain the nature of their associations or dependencies. This study provides evidence indicating that a significant proportion of prospective Islamic religious teachers had a worldview characterised by exclusivity. Their exclusivist stance is seen in their acknowledgment of sects that deviate from their own, such as Wahhabism, Shia, and those engaging in non-scriptural forms of worship. Some individuals agree with the designation of heretical being attributed to those who adhere to distinct religious worship customs. Moreover, these individuals perceive contentious theological assertions, such as those made by Sheikh Panji Gumilang, as warped, misguided and beyond redemption.Contribution: This study implies the need to review and reconstruct higher education curricula to prepare prospective Islamic religion teachers who are moderate, tolerant, inclusive, and uphold human rights.
