The study examined the 2009 overseas program of the SNU Intensive English Teacher Training Program (IETTP) to evaluate overall management and its effects for future improvements. Following an overview of the 2009 overseas program, the present study provides the results of the program survey and English proficiency tests that were conducted on 42 trainees. The results indicated that the program was successful in terms of its management and improving English teachers' English proficiency. Especially, the trainees showed strong satisfaction for school visits, culture excursions, and special lecture series which exposed them to invaluable experience of looking into an English speaking country. Three suggestions were proposed in terms of managing and evaluating the overseas program of the IETTP. First, the IETTP needs to take proaction in identifying the needs of in-service English teachers and to reflect those needs in its overseas program. Second, the IETTP needs to develop a customized overseas program which can best support main goals of its overall six-month training program. Lastly, an evaluation of the program needs to incorporate more than just a survey method to triangulate the outcome of the study.
