APA 7 Citation Guide for Undergraduate Papers

Introduction

APA (American Psychological Association) format is the standard for social sciences, psychology, education, and business papers. Yet it remains one of the most commonly misapplied citation styles. This guide covers the most frequent APA 7 errors and shows you exactly how to correct them.

In-Text Citations: The Basics

Author-Date System

APA uses an author-date citation system. The basic format includes:

• Author's last name
• Year of publication
• Page number (for direct quotes only)

One Author

Format: (Author, Year, p. X)

Correct: "According to Smith (2019, p. 45), active learning increases retention rates."

Common Error: Forgetting the page number for a direct quote

Two Authors

Format: (Author1 & Author2, Year)

Correct: "Research shows significant correlation between sleep and academic performance (Brown & Martinez, 2020)."

Common Error: Using "and" instead of "&" in parenthetical citations

Three or More Authors

First citation: (Author1, Author2, & Author3, Year)

• Example: (Johnson, Lee, & Williams, 2021)

Subsequent citations: (Author1 et al., Year)

• Example: (Johnson et al., 2021)

No Author

Format: (Organization Name, Year)

• Example: (World Health Organization, 2022)

Direct Quotes

Always include page numbers for direct quotes.

Correct: "Learning is 'fundamentally social in nature' (Vygotsky, 1978, p. 52)."

Reference List: Formatting Rules

Your reference list should:

• Be alphabetized by author's last name
• Use hanging indents (first line flush left, subsequent lines indented)
• Include DOI or URL when available
• Use sentence case for titles (only capitalize the first word and proper nouns)
