IB Psychology: A Complete Guide for Students and Parents

Continuing our A-Level and IB Subject Guide Series, this week we take an in-depth look at IB Psychology, a fascinating subject that explores human behavior, cognition, and social interactions. Available at both Standard Level (SL) and Higher Level (HL), IB Psychology equips students with analytical, research, and critical thinking skills, making it an excellent subject for those interested in psychology, neuroscience, education, and social sciences.

If you’re considering taking IB Psychology, this guide will help you understand the subject structure, the differences between SL and HL, the assessments, and how to succeed.

What is IB Psychology?

IB Psychology is the scientific study of mental processes and behaviour, combining elements of biology, sociology, and cognitive science. The course is designed to develop a broad understanding of human thought and behaviour through various research approaches and applications.

Core Approaches to Behaviour (Both SL and HL)

The foundation of IB Psychology is built on three major psychological perspectives:

✅ Biological Approach – How genetics, brain structures, and neurotransmitters affect behaviour.
✅ Cognitive Approach – Examining memory, perception, thinking, and decision-making.
✅ Sociocultural Approach – Understanding how social and cultural factors shape human behaviour.

‍

Additional Topics (HL Only)

📌 The HL Extension: HL students explore one additional topic, which varies by school but may include:

• The impact of technology on cognitive processing and behaviour.
• Globalization and its psychological effects on identity and mental health.

‍

Optional Topics (One for SL, Two for HL)

Students choose applied psychology topics from the following options:

✅ Abnormal Psychology – Mental health disorders, diagnosis, and treatment.
✅ Developmental Psychology – How people grow and change over their lifespan.
✅ Health Psychology – The link between psychology and physical health.
✅ Psychology of Human Relationships – Interpersonal relationships, group dynamics, and conflict resolution.
‍

SL vs. HL: What’s the Difference?

While both SL and HL cover the same foundational topics, HL students are required to:

• Study an additional topic (the HL extension).
• Cover two optional topics instead of one.
• Complete an additional Paper 3 exam based on qualitative research methods.
• Explore studies in greater depth, analysing more research and theories.

✅ SL is ideal for students who want a general overview of psychology without extensive additional workload.
✅ HL is recommended for students who are considering psychology-related university degrees or careers.

📌 Paper 3 (HL Only: 20%) – Qualitative Research Methods (1 hour)

What GCSE Grades Are Recommended for IB Psychology?

✅ English (Grade 6 or higher) – Essential for essay writing and critical analysis.
✅ Science (Grade 6 or higher) – Biology helps with the biological approach content.
✅ Maths (Grade 5 or higher) – Some statistical analysis is required, especially for the IA.
