Concentration Test: Format, Examples and Preparation

Jul 5, 2026 · 5 min read

The concentration test hides a hard task behind trivially simple stimuli. Triangles appear one after another, and all you do is compare each one to the one before it. What makes candidates sweat is the rule: it tells you which attribute matters right now, it binds that attribute to a button, and it changes as the session goes on. This guide explains the format, the rule logic, and the working rhythm that keeps your accuracy stable for a hundred trials.

What is the Concentration Test?

The test measures selective attention under a changing rule set: your ability to compare stimuli on exactly one attribute while actively ignoring the others, and to swap that attribute the moment the briefing changes. That is a very aviation-specific mental motion. A pilot scanning an approach chart attends to minima while ignoring everything else on the plate; a controller comparing two radar labels attends to level, then to speed, then to level again.

Each triangle has three attributes: a colour, a direction it points, and a number of dots. The active rule names which attributes map to the TOP and BOTTOM buttons. You compare the current triangle to the previous one and answer: does the TOP attribute match, does the BOTTOM attribute match, or does neither match? The comparison itself is easy; holding the binding steady while triangles flow past is the test. It pairs naturally with the sustained attention test, which stresses endurance rather than rule switching.

Which Exams Include the Concentration Test?

Attribute comparison tasks with rule briefings are a recognizable fixture of aviation screening. Candidates commonly report this test type in:

  • DLR screenings, where the SKT style concentration stage is a classic hurdle
  • COMPASS and Advanced COMPASS by EPST, in the attention sections
  • PACE, in airline and cadet programme assessments
  • ADAPT, within its cognitive battery
  • Aon / cut-e batteries, which use closely related comparison tasks

Providers update their content without notice and publish no official syllabus, so treat this as candidate-reported guidance rather than a guarantee.

How the Test Works: Format and Rules

TOP = DIRECTION · BOTTOM = COLOUR
Tutorial step 1 of 4: Read the rule

The mechanics in order:

  • A briefing shows the current rule, for example TOP is bound to direction and BOTTOM is bound to colour. Read it carefully; everything depends on it.
  • Triangles appear one at a time. Each has a colour, a pointing direction and a dot count.
  • Compare the current triangle to the previous one, only on the two attributes named in the rule.
  • If the TOP attribute matches, press TOP. If the BOTTOM attribute matches, press BOTTOM. If neither matches, press NO MATCH.
  • After a block of trials the rule changes and a new briefing appears.

Suppose the rule binds direction to TOP and colour to BOTTOM. The previous triangle pointed up and was grey; the current one points up but is red. Direction matches, colour does not: the correct answer is TOP. This is exactly how it looks in the test:

The session grows in length and rule churn together:

  1. Level 1: 20 trials under a single rule
  2. Level 2: 40 trials, 2 rules
  3. Level 3: 80 trials, 4 rules
  4. Level 4: 100 trials, 5 rules
  5. Level 5: 120 trials, 6 rules

At the top level a fresh briefing arrives every 20 trials, which is exactly often enough to catch anyone coasting on autopilot.

The triangles never get harder. What gets harder is staying loyal to a rule you read forty triangles ago.

Scoring: What a Good Result Looks Like

Every trial scores as correct or not, and assessors read the error pattern as much as the total. Random scattered errors suggest attention drift; a cluster of errors right after each briefing suggests slow rule adoption, which is the most common and most fixable weakness. A strong result holds accuracy above ninety percent with no post-briefing dip. Speed matters less than most candidates assume; a steady rhythm with clean answers beats fast streaks broken by corrections.

How to Prepare: Strategies That Actually Work

  1. Verbalize the binding at every briefing. Say it once in your head as a sentence: direction up top, colour below. Candidates who skip this start each block with two cheap errors.
  2. Compare in rule order, always. Check the TOP attribute first, then the BOTTOM one, every single trial. A fixed micro-procedure leaves no room for improvisation under fatigue.
  3. Let the previous triangle go immediately. Once answered, the current triangle becomes the new reference. Holding old triangles in mind is wasted load.
  4. Practice the switch, not just the comparison. Short sessions with frequent rule changes train the expensive part. Long single-rule marathons feel productive and train almost nothing.
  5. Build a two-beat rhythm. See, answer. Rushing ahead of the rhythm is where impulse errors live.
  6. Warm up your memory for briefings with the visual memory test; encoding a rule quickly is the same skill as encoding a pair.

Common Mistakes to Avoid

  • Answering from the wrong reference, comparing to a triangle from three trials ago.
  • Carrying the old rule into a new block. The first trial after a briefing deserves an extra half second.
  • Drifting into pattern guessing when triangles repeat. The test shuffles attributes precisely to punish this.
  • Treating NO MATCH as a fallback for uncertainty. It is a positive answer that both attributes differ, not an escape hatch.
