SACE Stage 2 Psychology is the Year 12 South Australian psychology subject, a 20-credit course assessed both internally (by your school) and externally (by a single examination). This page is the index: it sets out the course structure, the assessment breakdown, and links to every dot-point answer we have written.

The five topics in 2026

Topic 1: Psychology of the Individual
What makes each person distinct, covering theories of personality (psychodynamic, humanistic, trait and social-cognitive) and intelligence and how it is measured.
Topic 2: Psychological Health and Wellbeing
How mental health and disorder are defined and explained, including models of mental health, stress and coping, and treatments and interventions.
Topic 3: Organisational Psychology
How psychology applies in workplaces, covering motivation and leadership, and group behaviour and the workplace.
Topic 4: Social Influence
How others shape our behaviour, covering conformity and obedience, attitudes and attribution, and prejudice and discrimination. This is a key external-exam topic.
Topic 5: The Psychology of Learning
How behaviour is learned, covering classical conditioning, operant conditioning and observational learning. This is the other key external-exam topic.

All five topics are underpinned by science inquiry skills: designing and conducting investigations, analysing and evaluating data, and applying ethical principles.
