Abstract The purpose of this study was to investigate the effectiveness of a program based on SCAMPER model in developing the creative thinking skills in English language (fluency, flexibility, originality and elaboration) among PreMaster Degree in Education students. The study adopted the quasi-experimental design that involved one experimental group. The sample of the study consisted of 115 students enrolled in the Department of Curriculum and Instruction at Cairo University. The experimental group was taught a program based on SCAMPER model for twelve weeks, two hours per week, during the second semester of the academic year 2022/2023. To collect data, a prepost creative thinking skills test was administered to the experimental group. The results of the study indicated that there were statistically significant differences between the mean scores of the experimental group in the pre and post administration of the creative thinking skills test in favor of the post administration of the test. Therefore, the researcher recommended training EFL instructors, teachers, prospective teachers and learners on using the SCAMPER model for developing English language skills in general, and the creative thinking skills in particular.
