This research was a descriptive study that used observation, interviews, documentation and focus group discussion to collect research data. Different data collection techniques or triangulations were used to analyze the research. The result of study showed that there was an influence between Islamic religious education in schools with religious instruction in the family, which assumed responsibility for Islamic religious education for children. It was found that the teacher acts only as a substitute for parents who provide Islamic religious education in schools in the form of subject matter.
