This research considers the benefits of using ER as a means to raise the TOEFL test scores of poorly motivated students in an L1 settings. Using a sample of 295 university level students it was found that moderate levels of reading can be effective in helping raise scores and in reducing score attrition. An imbalance in score gains for across the gender divide and the language ability spectrum suggest due consideration of the student profile is required at the time of implementing an ER programme.
