The data source of the study consisted of school principals, Islamic Education (PAI) teachers, and students in three primary schools, namely SDN 08 , SDN 12, and SDN 04 in Lembah Melintang District, West Pasaman Regency, West Sumatra Province, Indonesia. Data collection techniques were done through observation, interviews, and documentation. Then the data analysis procedure was carried out in three levels, namely data reduction, data presentation, and conclusion drawing. This research also found two notable things: first, generally teachers were not ready to teach Islamic Education in the aspects of planning, implementing, and evaluating student learning outcomes. Second, the unpreparedness of the teacher to teach Islamic Education is caused by internal factors, namely the teacher itself and externally, the lack of the supporting facilities of the school where the teacher carries out his work. More fundamentally, the readiness to implement Islamic Education learning in accordance with the The revised 2013 curriculum that is caused by internal factors. PAI teachers are not well supported by external factors.
