The purpose of this study is to examine the effectiveness of the inclusive PAI teaching material model on religious tolerance and eradication of radicalism in Indonesian students. Survey institutions show that religious minorities experience violations of freedom of religion and belief. Various studies indicate that about 50% of students are intolerant and have more contact with Takfiri Salafis. The negative social media posts by students leads to the negative publicity against Islamic Religious Education (PAI) lecturers. Although the PAI course aims to build students' religiosity and tolerance, it contains minimal relevant content. A sample of 460 students, specifically 230 experimental and 230 control classes, were tested using the Quasi-experimental method. The results showed that inclusive PAI teaching material is more effective in increasing religious tolerance and reducing radicalism. Therefore, PAI lecturers need to adopt this method to increase students' tolerance.
