ACADEMIC WRITING · APA 7TH EDITION
Page numbers and running heads
Student papers normally use only a page number in the header, including on the title page. Add a running head only if your instructor or institution asks for one.
Professional papers use a shortened title in uppercase at the left of the header and the page number at the right. Do not add the old “Running head:” label. A running head is limited to 50 characters, including spaces and punctuation.
