Academic writing is one of the skills needed by students, especially postgraduate students. However, there were still many writing problems experienced by Islamic Education Management Postgraduate students of IAIN Curup batch 2020. Therefore, it was necessary to develop a learning model for Academic Writing course. This study aims to investigate the development of a learning model in the Academic Writing course. This study used 4D development research model (Define, Design, Develop, and Disseminate). The result of the study shows that the learning model in the Academic Writing course was carried out into these stages: prewriting stage, drafting stage, responding stage, revising stage, and evaluating stage. By carrying out the academic writing course, there were improvements in the writing skills of the postgraduate students. In the prewriting stage, it was observed that the students had already the skills needed to be possessed in the pre-writing stage. Then in the writing stage, the students had possesed skills in processing or analyzing data, and the students also had been able to revise their writings.
