AP Psychology Curriculum Framework & Components
The AP® Psychology curriculum framework outlines the structure of the course and defines what students are expected to learn throughout the academic year. Published in the official Course and Exam Description (CED), the framework ensures that AP Psychology aligns with an introductory college-level psychology course.
The curriculum is organized around 2 core components: course content and science practices. Together, these components guide instruction, learning objectives, and assessment expectations. Understanding how the framework is structured helps students approach the course with clarity and purpose.
AP Psychology Course Content
The AP Psychology course content is divided into five units, each centered on a major area of psychological study. These units progress from biological foundations of behavior to cognition, development, social processes, personality, and mental and physical health.
Within each unit, students explore key concepts, theories, and research findings that explain how individuals think, behave, and interact with their environment. The content framework emphasizes both foundational knowledge and the application of psychological principles in real-world contexts.
Because AP Psychology mirrors a one-semester introductory college course, it requires students to engage deeply with concepts rather than rely solely on memorization. Mastery of course content supports success across both multiple-choice and free-response assessments.
AP Psychology Course Science Practices
When taking AP Psychology, the science practices and skills outline what concepts students should master. While exploring the course, you’ll acquire skills that include understanding psychological concepts, analyzing data, and analyzing research studies. Please note that Science Practices 1-3 will be tested in the MCQ section, whereas Science Practice 4 will only be assessed in the FRQ section.
There are 4 science practices for the AP Psychology course and exam:
Practice 1: Concept Application
This science practice focuses on psychological perspectives, theories, concepts, and research findings to understand and address different situations and challenges.
Practice 2: Research Methods and Design
This science practice involves evaluating qualitative and quantitative research methods, and study designs to assess their validity and effectiveness.
Practice 3: Data Interpretation
This practice emphasizes analyzing how psychological concepts are represented in research through tables, graphs, charts, figures, and diagrams, using both qualitative and quantitative data.
Practice 4: Argumentation
This science practice involves developing and supporting psychological arguments with evidence-based reasoning and research findings.

AP Psychology Units, Topics, and Key Concepts
AP Psychology has 5 units. Each focuses on a set of topics that explore a theme and carries a specific weight on the exam. While the College Board publishes the unit weighting for the exam's multiple-choice questions (MCQ) section, the amount each unit will apply toward the free-response questions (FRQ) section is always confidential. A unit's weight determines how often questions appear on the exam. The table below shows the unit weights for the MCQ section of the AP Psychology exam:
| Units | Weight |
|---|---|
| Unit 1: Biological Bases of Behavior | 15–25% |
| Unit 2: Cognition | 15–25% |
| Unit 3: Development and Learning | 15–25% |
| Unit 4: Social Psychology and Personality | 15–25% |
| Unit 5: Mental and Physical Health | 15–25% |
To strengthen your understanding of concepts across all five units, a comprehensive AP Psychology Study Guide can help reinforce terminology, theories, and research applications throughout the course.
