Introduction
Struggling to decide between APA vs MLA for your student essay? You’re not alone. Every semester, thousands of college students face this dilemma, especially when assignment guidelines are vague or professors assume you know the rules. Choosing the wrong citation style can cost points on formatting alone – up to 20% in some courses.
The good news? It boils down to your discipline. APA (American Psychological Association, 7th edition) dominates social sciences, education, and health fields, emphasizing recency with author-date citations. MLA (Modern Language Association, 9th edition) rules humanities like literature and languages, focusing on author-page for literary analysis.
This guide breaks down APA MLA differences, provides a discipline matrix for 20+ fields, a step-by-step decision tree, common pitfalls with a checklist, real examples, and tools. By the end, you’ll confidently choose APA or MLA for essays – or know when to ask for help. Let’s dive in.
Whether you’re writing a psychology research paper or analyzing Shakespeare, matching the right style boosts credibility and saves time. Purdue OWL and Scribbr confirm: discipline dictates style 90% of the time.
APA vs MLA: Core Differences
When comparing APA vs MLA, start with citations, references, and paper setup. APA prioritizes publication dates (key for evolving sciences), while MLA spotlights page numbers (ideal for timeless texts). Here’s a side-by-side from official sources:
| Aspect |
APA (7th ed.) |
MLA (9th ed.) |
| In-text Citation |
(Author, Year, p. #) e.g., (Smith, 2020, p. 23). Narrative: Smith (2020) argues… Et al. for 3+ authors. |
(Author Page) e.g., (Smith 23). Narrative: Smith notes… Et al. for 3+. Purdue MLA |
| Reference List |
“References” – Alphabetical, sentence case titles, DOI/URL, date after author. Hanging indent. APA.org |
“Works Cited” – Alphabetical, title case, stable URL, date at end. Hanging indent. |
| Title Page |
Yes: Title, author, affiliation, course, instructor, date. No running head for students. |
No: Header (name, instructor, course, date) top left. Title centered. |
| Font/Margins |
12pt Times New Roman/Calibri, double-space, 1″ margins. |
Same: 12pt legible font, double-space, 1″ margins. |
