The study of psychology enables students to understand their own behaviours and the behaviours of others. Psychological knowledge can be applied to improve outcomes and the quality of experience in various areas of life, such as education, intimate relationships, child rearing, employment and leisure.

Psychology builds on the scientific method by involving students in the collection and analysis of qualitative and quantitative data.

By emphasising evidence-based procedures (i.e. observation, experimentation and experience), the subject allows students to develop useful skills in analytical and critical thinking, and in making inferences by employing evidence-based procedures.
