Section 2.8 of the APA Manual, 7th edition, provides details on the running head. A shortened version of the paper’s title (50 characters or fewer, including spaces and punctuation), the running head appears on top of each page so that the readers can connect the paper’s content with the title. While running heads are not required for student papers unless explicitly stated by the organization or instructor, manuscripts for publication absolutely require them.
Running heads should be in all-capital letters, flush left (directly across from the page number, which is flush right), and presented in the page header including the title page. You do not need to use the words, “Running head” because it is implied from its presence in the header.
Example:
Comparison of Loan Repayment Between Traditional Lending and Online Lending Models (Heading)
COMPARISON OF LOAN REPAYMENT MODELS (Running Head)
