APA Style


The American Psychological Association publishes a style guide, which details writing conventions that have been adopted as the standard format for scholarly publications in many disciplines, not just psychology. The APA style is one of many professional styles. During the course of your career, you may be asked to write according to APA style or one of the other styles. Even if you are not writing to a given style, adopting the conventions of APA format will help you to standardize your writing and communicate with your intended audience more effectively. Remember that the goal of a writing style guide is to improve communication. The definitive source for APA formatting style is the Publication Manual of the American Psychological Association (5th edition). There are numerous additional resources available from a variety of sources, but the Publication Manual itself is the source authority.
