Psychological Tests at ISSB: WAT, SRT, SCT and TAT Explained
Psychological Tests at ISSB: WAT, SRT, SCT and TAT Explained
The psychological battery is typically the first major event at ISSB — and in many ways, the most important. The impression you create through your WAT responses, your SRT stories, your sentence completions, and your self-description travels with you through every subsequent activity. The psychologist contributes to the final conference, and their assessment is based almost entirely on this early phase.
That makes the psychological tests both high-stakes and underserved by the way most candidates prepare for them. Cramming is useless here. What works is understanding what each test actually measures, practising under authentic conditions, and — most importantly — doing the real self-development work that makes your responses reflect a person genuinely suited to commissioned service.
This guide covers all four tests in the standard ISSB psychological battery.
Why Psychological Tests Exist at ISSB
The armed forces invest enormously in officers — years of training, education, and responsibility. Before making that investment, they need confidence that a candidate has the psychological profile that will allow them to grow into the role: stability under stress, a constructive orientation toward challenge, the capacity to lead and be led, and the self-awareness to keep learning.
Psychological tests are not lie detectors. They are instruments for surfacing patterns — in how you think, what you value, how you respond to difficulty, and how you relate to others. A single response does not define you. Your overall pattern does.
1. Word Association Test (WAT)
What It Is
A word is displayed on screen (or written on a board, depending on the centre and format) for ten seconds. You write down the first complete sentence that comes to mind. The next word appears. This continues for a set number of words — typically sixty or more.
What It Measures
WAT is designed to bypass your deliberate, edited self and surface your instinctive response patterns. In ten seconds, there is not enough time to carefully construct a socially desirable answer. What you write reveals:
- Your underlying attitudes toward authority, risk, failure, success, and social relationships
- Whether your orientation is generally active or passive — do your sentences involve people doing things, or things happening to people?
- Your emotional tone — constructive and energetic, or anxious and preoccupied?
- Thematic patterns that repeat across multiple words
How to Prepare
Practise under real timing. This is the single most important thing. Write your first genuine response within ten seconds, do not edit, and move on. Most candidates who have not practised underestimate how difficult this is — the clock runs out before they have decided what to write.
Review your patterns, not individual responses. After a practice round, read back through what you have written. What themes recur? Do your sentences tend to be active or passive? Positive or negative? Personal or abstract? This review shows you what a psychologist would see — and points you toward genuine development work, not surface adjustment.
Build an active, constructive orientation. Over time — not in a week — work on reframing how you process challenge and difficulty. When you encounter a setback in daily life, practise describing it (even just to yourself) in terms of what you learned and what you will do next. This shifts the underlying pattern that WAT surfaces.
Do not memorise ideal responses. A practised word list with prepared "good" sentences produces flat, inconsistent responses that trained psychologists identify quickly. Your preparation should build genuine qualities, not a rehearsed overlay.

2. Situation Reaction Test (SRT)
What It Is
You are given a booklet of short situation descriptions — typically sixty scenarios over a set time. Each describes a situation you might encounter: a conflict, an emergency, a leadership challenge, an ethical dilemma. You write down what you would do.
What It Measures
The SRT assesses how you respond to challenge and responsibility. Specifically, it looks at:
- Initiative: Do you act, or do you wait for someone else to step in?
- Social responsibility: Do your responses account for others' wellbeing, or only your own?
- Judgment: Are your responses proportionate, practical, and sensible?
- Leadership orientation: When a situation calls for someone to lead, do you step up?
- Composure: Do your responses reflect calm, clear thinking under pressure?
How to Prepare
Practise under time pressure. Sixty situations in a limited time means you have roughly a minute or less per scenario. Candidates who have not practised tend to spend too long on the early scenarios and rush the later ones.
Lead, cooperate, and seek help appropriately. Good SRT responses involve you as an active agent — acting, organising, involving others where appropriate. They are not passive (wait and see what happens) or reckless (charge in without thinking).
Be honest. Do not write what you think the "ideal officer" would do if it does not reflect your actual thinking. The SRT is long enough that your genuine patterns emerge regardless. Your goal is to develop responses that reflect genuine qualities — active, responsible, clear-headed — not to perform them.
3. Sentence Completion Test (SCT)
What It Is
You are given the beginning of a sentence and asked to complete it. Unlike WAT, you typically have a few seconds longer per item — but the stems are more specific, probing particular domains of your psychology.
Common stem categories include:
- Relationships with authority ("When my superior gives me an order I disagree with...")
- Relationships with peers ("The people I work with...")
- Attitudes toward failure ("When I make a mistake...")
- Ambition and self-belief ("I believe I am capable of...")
- Social attitudes ("When someone needs help...")
What It Measures
The SCT maps your attitudes in a more structured way than WAT. Because the stems are targeted at specific domains, the psychologist can assess your relationship with authority, your ego strength, your social warmth, your resilience, and your ambition with more precision.
How to Prepare
Complete stems honestly and naturally. Forced completions that try to project an ideal self produce an inconsistent profile. Your genuine strengths should come through naturally; work on developing the qualities in areas where you are genuinely weaker.
Practise completing stems on paper. Read your completions back to yourself. Would someone reading these want this person leading their team? Where the answer is no, ask yourself what genuine work you need to do.
4. Thematic Apperception Test (TAT)
What It Is
You are shown a picture — typically an ambiguous scene depicting one or more people in some kind of situation. You have a limited time to write a story about the picture: who the people are, what is happening, what led to this moment, and how it will end.
What It Measures
TAT is the richest and most interpretively complex of the four tests. Because the images are ambiguous, the stories you project onto them reveal a great deal about your inner life:
- Motivation themes: What do your characters want? What drives them?
- Conflict and resolution: What kinds of problems appear in your stories? How do they resolve?
- Interpersonal relationships: How do your characters relate to each other — with trust, suspicion, warmth, competition?
- Agency: Are your characters active agents who shape events, or passive subjects to whom things happen?
- Emotional tone: Are your stories generally constructive and forward-looking, or preoccupied with failure and loss?
How to Prepare
Write stories with clear structure. A beginning (who are these people and what is the situation?), a middle (what challenge or conflict arises?), and an end (how does it resolve, and what changes as a result?). Psychologists are reading dozens of these stories; clarity and structure stand out.
Vary your themes. If your first five stories all involve the same kind of conflict or the same type of character, that pattern is noted. Practise responding freshly to each image rather than applying a template.
Aim for constructive resolutions. Not every story needs a perfect ending, but stories that resolve through characters taking responsible, purposeful action reflect well. Stories that end in tragedy, resignation, or unresolved conflict without a redemptive element raise questions.
Practise with different stimuli. The images you see at ISSB will be unfamiliar. Practising with a range of ambiguous images is more valuable than preparing specific responses to specific pictures.
The Self-Description Test (SDT)
Some ISSB formats include a Self-Description Test, in which you describe yourself — your personality, your strengths, your weaknesses, your aspirations — in structured written format. The SDT provides the psychologist with your self-model, which is then compared against what your WAT, SRT, and TAT responses actually reveal.
Prepare by writing an honest, considered self-description before your board. Read it critically: does this description reflect who you actually are, or who you think the board wants to see? Then ask the harder question: does the person described in this document have the qualities an officer needs? Where the answer is no, that is where your preparation work lies.
A Note on What Not to Do
Do not look for "correct answers." The psychological battery does not have answer keys. It has patterns — and trained psychologists are very good at distinguishing genuine patterns from manufactured ones.
Do not try to game the tests. Attempts to project a false persona are identifiable. They produce inconsistencies across the battery and between the battery and your GTO and interview behaviour. Consistency is actually a sign of health.
Do not neglect the substance for the surface. Time spent practising under authentic conditions is valuable. Time spent trying to learn which words to write is wasted.
