Although research has been done on the effects of Service-Learning in nursing, medical and engineering students, there is very little information about the effects that this methodology has on English pedagogy students. The present study conducted over two semesters attempted to identify the effects that this methodology had on EFL pedagogy undergraduate Chilean students. The participants were seventy English pedagogy students and one hundred and fifty community members. The needs of the community as well as the English level were identified with a needs analysis and diagnostic test. Reflection logs were used to identify the effects of the methodology on students while a satisfaction survey was used to identify the impact the methodology had on the community members. The analysis of the logs revealed that undergraduate students became aware of the importance of identifying the community´s needs, having clear objectives, preparing material and activities before designing a course and teaching a class. This methodology showed to have a positive effect on the teacher training students when referring to their professionalization and application of theory. For the community the results were positive but further research is needed to identify the full impact in the community members.
