Drawing on data provided by 5,811 students from schools in England, Wales, and London who self-identified as either 'no religion' or as Christian, this study explored the effect of the contact hypothesis (having friends who are Muslims) on scores recorded on the seven-item Scale of Anti-Muslim Attitude (SAMA), after controlling for type of school (with or without a religious character), location (England, Wales, and London), personal factors (sex and age), psychological factors (extraversion, neuroticism, and psychoticism) and religious factors (self-assigned affiliation as Christian, worship attendance, and belief in God). The data demonstrated the positive effect of having friends who are Muslim on lowering anti-Muslim attitudes. The path is then described from educational research to curriculum development in the design of resources that offer young learners vicarious experience of having friends who are Muslims.
