The purpose of this study was to identify areas of APA formatting that college instructors view as most problematic in student writing. Using a Likert-style survey, the greatest areas of reported concern were problems with documentation, specifically, citations, references, and quoting; of lesser concern were various style and formatting errors in student work. Respondents included 135 primarily undergraduate faculty members at institutions where APA style is the required documentation style across disciplines. While the Publication Manual of the American Psychological Association is the definitive source, there are a number of tools, resources, and strategies that may facilitate students' mastery of APA style guidelines. In addition to identifying instructors' concerns, we offer a number of instructional aids (i.e., teaching strategies, support resources, feedback bank, and a sample rubric) to help faculty address the main areas of concern.
