What is the correct APA style for article author followed by a job title, when as a byline?

In APA style, when a job title follows an author’s name in a byline, the title should be lowercase and separated by a comma. For example: The Use of Technology in US National Parks John Smith, editor in chief This format matches APA’s guidance for in-text citations and source listings, where job titles after names are not capitalized unless part of a formal heading (e.g., “John Smith, Editor in Chief” in a publication’s masthead). Since this is a byline, lowercase is appropriate. If the job title is part of the author’s official role (e.g., “John Smith, Editor in Chief of *Journal of Environmental Science*”), capitalize only the title itself. For example: The Use of Technology in US National Parks John Smith, Editor in Chief Double-check the context: if the title is generic (e.g., “editor”), keep it lowercase. If it’s a specific role tied to the publication, capitalize it. For clarity, consult the APA manual’s sections on bylines and source formatting. If no official example exists, prioritize consistency with your organization’s style.
