APA Mistakes Professors Hate (And How to Avoid Them)

APA Mistakes Professors Hate (And How to Avoid Them)

APA style is widely used in nursing, psychology, education, business, and healthcare programs. However, professors consistently report seeing the same APA mistakes semester after semester. Understanding these errors — and avoiding them — can significantly improve your grades.

1. Incorrect In-Text Citations

One of the most common APA mistakes professors hate is incorrect in-text citation format. Students often:

  • Forget the publication year
  • Place citations incorrectly within sentences
  • Use author first names instead of last names

APA in-text citations must include the author’s last name and year, and page numbers are required for direct quotations.

2. Improper Reference List Formatting

Many students lose marks due to careless reference list errors. Common issues include inconsistent formatting, missing DOIs, incorrect italics, and improper capitalization. In APA style, journal titles and volume numbers must be italicized, while article titles use sentence case.

3. Mixing APA With Other Citation Styles

Another major issue is blending APA with MLA or Chicago formatting. This includes using quotation marks incorrectly, formatting headings improperly, or citing sources inconsistently. Professors expect strict adherence to one citation style throughout the paper.

4. Incorrect APA Headings

APA headings follow a specific five-level structure. Professors often see:

  • Headings in bold and italics incorrectly
  • Inconsistent capitalization
  • Missing level differentiation

Incorrect headings make papers harder to read and signal poor attention to detail.

5. Overuse or Misuse of Direct Quotations

APA encourages paraphrasing over excessive quoting. Professors dislike papers filled with long quotations because they reduce original analysis. When quotations are used, they must be properly introduced, cited, and formatted according to APA rules.

6. Running Head and Page Number Errors

Although APA 7th edition simplified running heads, students still make mistakes. Common errors include incorrect placement, unnecessary running heads for student papers, or missing page numbers altogether.

7. Incorrect Font, Spacing, and Margins

Using the wrong font, spacing, or margins immediately signals APA non-compliance. APA requires double spacing, 1-inch margins, and approved fonts such as Times New Roman 12-point or Calibri 11-point.

8. Title Page Formatting Mistakes

Professors frequently penalize errors on the APA title page. Missing elements such as course number, instructor name, or institutional affiliation can result in lost marks even before the paper is read.

9. Missing or Incorrect Citations for Paraphrased Ideas

Many students mistakenly believe paraphrased ideas do not require citations. Professors strongly dislike this error, as it borders on plagiarism. Every borrowed idea must be properly cited, even when rewritten.

10. Not Using the Latest APA Edition

Finally, professors expect students to follow the most recent APA edition unless instructed otherwise. Using outdated rules leads to formatting inconsistencies and unnecessary deductions.

How to Avoid APA Mistakes Professors Hate

To avoid these errors, students should consult the official APA manual, use credible formatting guides, proofread carefully, and allow time for revisions. Professional APA editing can also help ensure accuracy and consistency.
