This paper provides a proven method for improving the quality of students’ business writing with limited effort by the instructor and minimal use of classroom time. The paper includes two handouts developed over several years by the author which highlight common errors students make in their business writing. Students receive the handouts with every writing assignment and the instructor explains how to use the handouts. The paper also provides a checklist which students complete and submit to the instructor with their writing assignments. The checklist requires students to verify whether they reviewed and corrected their writing for the business writing structure and common errors described in the handouts.
