SCSA Curriculum

What Psychology students actually study.

SCSA's Psychology course breaks into four units across Year 11 and Year 12. Half of the course is content (cognition, memory, the brain, social behaviour) and half is research methods: variables, sampling, ethics, and how to read a study without being conned by it. Below, what each unit covers and how it's assessed.

Unit 1
Biological and cognitive influences on the individual
Where psychology starts: the nervous system, how we sense and perceive, and the basics of research.
The nervous system
Neurons, the central and peripheral nervous systems, and how the brain produces behaviour.
Sensation and perception
Visual perception, depth cues, gestalt principles, and the gap between sensing and perceiving.
Research methods (intro)
Independent and dependent variables, controls, ethics, and reading a real study.
Assessment: School-assessed: investigations, tests, and an end-of-unit exam.
Unit 2
Self and others
How we form impressions, hold attitudes, and behave in groups.
Person perception & attribution
First impressions, fundamental attribution error, and how stereotypes form.
Attitudes & behaviour
How attitudes form and change, and when they actually predict behaviour.
Social influence
Conformity (Asch), obedience (Milgram), groupthink, and bystander effects.
Assessment: Tests, an investigation report, and the mid-year exam.
Unit 3
Memory, learning and the brain
ATAR-scored. Memory models, learning theories, and brain structure in detail.
Memory models
Atkinson-Shiffrin multi-store, working memory model, encoding, retrieval, and forgetting.
Learning theories
Classical conditioning (Pavlov), operant conditioning (Skinner), and observational learning (Bandura).
Brain structure & function
Lobes, hemispheres, neuroplasticity, and what brain imaging tells (and doesn't tell) us.
Assessment: 50% school-assessed: investigations, tests, and an internal exam.
Unit 4
Personality, intelligence and psychological disorders
External exam prep. The applied end of the course: clinical psychology, treatments, and individual differences.
Personality & intelligence
Trait theories, IQ testing, cultural fairness, and the limits of psychometric measurement.
Psychological disorders
Anxiety, mood and psychotic disorders, the biopsychosocial model, and how diagnoses are made.
Treatments & interventions
CBT, medication, lifestyle interventions, and the evidence base behind each approach.
Assessment: External exam, 3 hours, with multiple-choice, short-answer and extended-response sections.
ATAR exam structure

How the Year 12 exam is laid out.

SCSA's Psychology ATAR external exam runs for three hours plus ten minutes reading time. School-assessed marks count for 50% of your final ATAR score; the external exam counts for the other 50%. The paper samples both Unit 3 and Unit 4 content with research methods threaded through every section.

Section 1
Multiple choice
Knowledge recall and short application items.
Format
Around 30 multiple-choice questions covering content from across Units 3 and 4, plus research-method scenarios.
Weight
Roughly 25–30% of the total exam mark.
What's tested
Definitions, study designs, ethics, and the ability to read a short scenario and pick the correct construct.
Strategy: Read every option before answering. Distractors usually swap a single variable (independent vs dependent, validity vs reliability).
Section 2
Short answer
Multi-part questions that scaffold from describe to apply to evaluate.
Format
Around six short-answer questions, each broken into parts with marks rising from 1–2 marks to 6–8 marks at the back end of the question.
Weight
The largest section by marks. The majority of your raw score is decided here.
What's tested
Direct content recall, applied research methods (identify the IV, propose a control, name the ethical issue), and brief evaluations.
Strategy: Read the directive verb. "Describe" is not "explain"; "evaluate" wants both sides plus a judgement.
Section 3
Extended response
Essay-style questions where structure and integration carry the marks.
Format
A small number of extended-response questions; some compulsory, some with a choice. Each is worth around 20–30 marks.
Weight
Around 25–30% of the exam.
What's tested
Extended argument: define the construct, describe a relevant theory or study, apply it to the scenario, evaluate strengths and limitations.
Equipment: Black or blue pen, pencil for diagrams. No calculator is required (Psychology has no quantitative sections). No formula sheet is supplied.
What examiners reward

Common student mistakes in Psychology.

SCSA's annual examination reports flag the same patterns year after year. Knowing them is half the battle. The strongest Psychology candidates are not the ones who memorise the most studies, they're the ones who answer the question that's actually been asked, in the language the marking key uses.

1
Naming the directive verb, not the topic
"Describe" wants features. "Explain" wants causation. "Compare" wants both similarities and differences. "Evaluate" wants a judgement supported by evidence. Students who treat all four the same way leave marks on the table in every short-answer question.
2
Sloppy research-methods vocabulary
Confusing reliability with validity, mixing up independent and dependent variables, or labelling a third variable as a "confound" without saying which variable it confounds. Examiner reports return to this every year. Use the textbook definition; don't paraphrase it.
3
Naming a study without using it
Citing Milgram, Loftus or Bandura without explaining how the study supports the point on the page. Marks come from the link, not the name-drop. Two sentences of "and this matters because..." is what the marking key is looking for.
4
Extended responses with no structure
A 25-mark question is not one long paragraph. Strong responses use clear paragraphing: definition, theory, study evidence, application to the scenario, evaluation. Examiner reports consistently note that structure is the single biggest mark-grabber at the top end.
5
Treating Psychology as memorisation
There is content to remember, but the exam doesn't test recall in isolation. It tests whether you can use a theory to interpret a scenario you've never seen before. Build flashcards, but pair every flashcard with a "where would I use this?" prompt.
6
Running out of time on the extended response
Plan for around 90 minutes on the short answers and around 50 minutes on extended response. The most common mistake in low-scoring papers is over-investing in the short answers, then writing a rushed conclusion that throws away the structure marks.
Career & uni pathways

Where Psychology leads in WA.

Psychology is a List A course (humanities & social sciences) and counts toward general university entry at every WA university. It is rarely a hard prerequisite, but it gives you a head start in any degree where research methods, behaviour or human science matters. The four big WA pathways:

UWA
Psychology, Behavioural Science, Med-related
UWA offers a Bachelor of Psychological Science and a Psychology major within the Bachelor of Science. ATAR Psychology is not required but maps cleanly onto first-year Psych 1A/1B content. For Doctor of Medicine via assured pathway, Chemistry is the priority science, not Psychology.
Curtin
Psychology, Counselling, Speech Pathology
Curtin runs a Bachelor of Psychology (Honours) and a Bachelor of Science (Psychology). Speech Pathology and Occupational Therapy at Curtin draw heavily on Psychology graduates. Year 12 Psychology is recommended but not a hard prerequisite.
Murdoch & ECU
Criminology, Forensic, Education
Murdoch's Forensic Psychology and Criminology programs and ECU's Bachelor of Psychology and Counselling all accept ATAR Psychology as part of general entry. Notre Dame offers psychology pathways too. None of them require it as a Year 12 prerequisite.
After uni
The path to registered psychologist
A 3-year accredited Bachelor + a 4th honours year, then either a 2-year Master's or supervised practice gets you to registration in WA. Year 12 Psychology only saves you from one early "what is a control group?" lecture, but it builds the habit of reading studies critically, which compounds.

Common questions

Psychology FAQs.

Does Educatta teach Psychology?
Not currently. We focus on the six core ATAR subjects most students sit: Maths Methods, Maths Applications, English, Chemistry, Physics and Human Biology. Psychology is on the shortlist for future subjects given how big the WA cohort has become. Email us if you'd like us to track your interest.
Is Psychology a "real" science for university entry?
Yes. SCSA Psychology is a List A (science) ATAR subject and counts toward the science requirement at WA universities. UWA, Curtin and Murdoch all accept it for psychology, criminology, social work, education, nursing and most arts degrees. It does not, however, replace Chemistry for medicine or Physics for engineering, those still want the lab sciences specifically.
Is Psychology easier than Chemistry or Physics?
Different, not strictly easier. Psychology has less maths than Physics and less abstract conceptual work than Chemistry, but it's writing-heavy and the research-methods component is more rigorous than students expect. Strong English students who like structured argument tend to do well. The cohort is large and the spread is wide, so the top students still need to work hard for top marks.
Does Psychology scale well?
Roughly neutral. Psychology has scaled around the cohort midpoint for several years, give or take a couple of points. Don't pick Psychology for the scaling; pick it because the content interests you and you can sit in the top third of the cohort. Sitting at the median in Psychology will hurt your ATAR more than sitting at the top of Applications would.
If you don't teach Psychology, what should I do?
If your school offers Psychology and you love it, take it there and use Educatta for your other ATAR subjects, especially ATAR English (the writing skills carry directly into Psych extended-response answers) and Human Biology (the brain and disease content overlaps). Sit a free trial and we'll set you up with the right complementary subjects.
How is the Psychology external exam structured?
Three sections across three hours plus 10 minutes reading time: multiple choice, short answer (the largest section by marks), and extended response. The short-answer section is where most of your final mark is decided. There's no calculator and no formula sheet, just black or blue pen and a pencil for diagrams. School-assessed marks count for 50% of the final ATAR mark; the external exam counts for the other 50%.
Do I need Year 11 Psychology to take Year 12 Psychology?
Most schools require it. Year 11 builds the research-methods vocabulary (variables, sampling, ethics) that Year 12 assumes you already know, plus the foundation content on the nervous system and social influence. A few students transfer in from another science and catch up with extra reading, but it's a steep climb. Talk to your school before you commit.
How much study do top Psychology students do?
The top scorers consistently report two patterns: weekly active recall on flashcards (research designs, key studies, definitions), and timed past-paper practice from August onwards. Reading the textbook three times does not work. Practising with the marking key in front of you does. SCSA publishes recent past papers and marking keys on its Psychology past exams page.
Is Psychology good prep for studying psychology at uni?
It's a useful head start, not a requirement. UWA, Curtin, Murdoch, ECU and Notre Dame all run psychology programs that don't require Year 12 Psychology for entry. What it does give you is familiarity with research methods (which dominates first-year units), and a sense of whether the subject fits your brain before you commit to a 3 or 4 year degree.
