This paper might have some suggestions for language teachers. As it was shown, the level of learners' self-esteem has a significant effect on the fluency of learners' speaking. So it might be helpful if teachers pay more attention to their students' level of self-esteem and try to enhance it. Also considering the age of students is important for decision making purposes since it affects performance. Knowing this, teachers might be less critical on the performance of older learners and give them more time and make the necessary changes in their approaches to enable them to catch up with the younger ones. The factors of self-esteem, age should also be considered by materials developers.
English language learners could also benefit from the findings of this study to become aware of the impact of self - esteem and age and make appropriate decisions to enhance their self-esteem and also to begin learning a second language at an earlier age.
