Psychology Scaling WACE 2026: Does It Scale Up or Down?

TISC scales every WACE subject before an ATAR is calculated. The TISC scaling report is the authority on what this subject did.

Does WACE Psychology scale up or down?

TISC scales every WACE subject before an ATAR is calculated.

TISC does not publish a per-subject raw-to-scaled conversion for this course in a form we can quote exactly, so there is no figure on this page — the direction above is sourced from the TISC scaling report linked below, and should be read as directional rather than numeric.

You can't change the scaling. You can change the raw mark.

Scaling is decided by your cohort, after the exam, and nothing you do moves it. The raw mark is the only part of this you control — and the Psychology hub is 20 full-length model exams with mark-by-mark answer guides, revision notes, practice questions and flashcards, built for exactly that.

What Psychology actually asks of you

School assessment is Science inquiry 20%, Response 40% and Examination 40%. The external paper has 10 minutes reading and 180 minutes working. The 2026 cover specifies six compulsory short-answer questions worth 134 raw marks and 70%, compulsory Extended answer Part A worth 26 raw marks and 10%, and a choice of one of two Part B questions, each worth 31 raw marks and 20%. Candidate raw total is 191; offered raw marks total 222. In 2025 the annual raw allocations were 142, 28 and 35, giving 205 attempted raw marks. Percentage weights are distinct from annual raw marks.

The 6 areas of study you are examined on

From the Psychology ATAR Year 12 syllabus — for teaching from 2026.

  • Unit 3 — Memory
    Sensation, perception and attention; multi-store and working-memory models; brain structures; remembering, rehearsal and forgetting.
    In the exam: Apply models to unfamiliar scenarios and evaluate evidence, including Craik and Tulving (1975).
    Where marks go missing: Attention is not a memory store, and one model does not explain every memory process.
  • Unit 3 — Learning
    Classical, operant and social learning, landmark studies and behaviour modification.
    In the exam: Distinguish stimuli, responses and consequences; evaluate method, ethics and application.
    Where marks go missing: Negative reinforcement strengthens behaviour by removing an aversive condition; it is not punishment.
  • Science inquiry
    Research questions, variables, designs, sampling, data, validity, reliability and ethics.
    In the exam: Justify a method and improvements in Unit 3 and Unit 4 contexts.
    Where marks go missing: Random sampling supports representativeness; random allocation supports group equivalence. Correlation does not establish causation.
  • Unit 4 — Motivation and wellbeing
    Sources of motivation, self-determination theory, Maslow, Diener and Ryff.
    In the exam: Apply and evaluate theories against evidence and varied contexts.
    Where marks go missing: Maslow is not an inflexible universal sequence; wellbeing is more than absence of distress.
  • Unit 4 — Stress
    Physiological, stimulus and transactional models, appraisal and coping.
    In the exam: Compare Selye, Holmes–Rahe and Lazarus–Folkman in a scenario.
    Where marks go missing: A stressor is not identical to the stress response.
  • Unit 4 — Sleep
    Sleep purposes, circadian timing, stages, deprivation and improvement.
    In the exam: Interpret evidence and evaluate He et al. (2020).
    Where marks go missing: An association between sleep and wellbeing does not by itself show causation.

How scaling works in Western Australia

In Western Australia, the SCSA moderates your school mark against the examination results, averages the moderated school mark and the examination mark 50/50 into a combined mark (a course with a practical examination combines each component 50/50 and weights the two as its syllabus states), and standardises it. TISC and the SCSA then scale every course at once with TISC's Average Marks Scaling: each course's mean scaled score is set to the mean its own students achieved across all their courses, so after scaling the mean of all scaled scores is 60 and a course mean above 60 has been scaled up. Your Tertiary Entrance Aggregate is your best four scaled scores plus 10 per cent of your Mathematics Methods, Mathematics Specialist and highest LOTE scaled scores, whether or not those courses are in your best four, to a maximum of 430; the ATAR is your rank on that aggregate against the whole Year 12 school-leaving-age population. Scaling is redone every year from that year's cohort, so a published scaled mean describes one past cohort and is never a guarantee.

What scaling is not

Scaling is not a difficulty rating and it is not a bonus. It compares how the students in one subject performed across every other subject they took, so a subject moves because of its cohort, not because of the paper. The consequence is practical: you cannot scale your way out of a weak result. The only lever you control is the raw mark, and the fastest way to move that is full-length timed practice against the real exam format.

Should I choose Psychology because of how it scales?

Scaling adjusts a whole cohort, not one student, so choosing a subject you will struggle in because it scales up is usually a worse trade than doing well in one that scales down. Check the prerequisites for the course you want first, then your interest and workload, and treat scaling as a tie-breaker. Scaling is also recalculated every year, so the figures in any report describe a past cohort rather than the year you are sitting.
