This study investigated the efficiency of self-editing to reduce language errors of nurse educators. To achieve this, a checklist was created and 15 nurse educators from three different universities were educated on how to self-edit throughout 10 weeks. Data were obtained through 3 editing tasks before the 10-week education course and 3 editing tasks after the course. The Wilcox on test analysed pre-tests and post-tests, and found a statistically significant difference in terms of noticing the language errors through self-editing. This study suggests nurse educators use the checklist before submitting a manuscript. Also, this study concludes that self-editing is an efficient way of revealing language errors and increasing accuracy in English writing of nurse educators.
