This study examines the potential effect of service-learning training on 38 EFL teachers from the public schools of the North-Eastern Badia Directorate of Education, Mafraq, Jordan. A quasi-experimental design was used, and the participants were randomly assigned into an experimental group (n=18) and a control group (n=20). As part of the treatment, the participants of the experimental group were asked to serve their community through collecting paper waste, recycling, and planting trees. They were then asked to videotape their activities to use them in their writing tasks in the classroom. The control group did not receive any treatment and taught the writing tasks per the guidelines of the prescribed Teacher's Book. The findings revealed statistically significant differences in the overall writing performance of both the experimental and control groups, in favor of the former. The findings also revealed that the use of service-learning training helped teachers form positive attitudes towards EFL writing.
