How to Cite a Case Study in APA Format - A Step-by-Step Guide with Examples

Writing



Case studies are important tools for the academic and professional world, offering in-depth investigations into specific circumstances, organizations, or individuals. Whether a student investigating a business situation, a researcher examining a social phenomenon, or a professional reporting on project results, case studies provide rich and detailed information. To maintain academic integrity and professional credibility, these sources must be properly referenced, and APA format is the standard style for such citations.

Citation is important because it:

  • Credits the original authors' work.
     
  • Strengthens your research or analysis.
     
  • Prevents misrepresentation of the original authors' intentions.

The American Psychological Association (APA) style is widely used in disciplines such as social science, education, and business. This guide provides step-by-step instructions, practical examples, and answers to frequently asked questions to help you confidently cite case studies in APA format.
