The NAV CANADA online assessment: four sections in 30 minutes
NAV CANADA's first screen is a timed online assessment of about 30 minutes covering inductive reasoning, concentration, spatial orientation and deductive reasoning. What each section asks, and how to prepare.
NAV CANADA’s first real gate is an online assessment you sit at home. It is short — around 30 minutes in total — and it decides whether you are invited to the in-person day.
Sourcing: the roughly-30-minute duration, the remote format and the one-year reapplication wait are published by NAV CANADA. The four-section breakdown and the per-section timings below are drawn from established third-party guides and candidate accounts, not from NAV CANADA, which publishes no section detail. Treat them as a reliable picture of the format rather than an official specification.
The four sections
The assessment is built on Aon’s cut-e instruments, which is why the same section names appear in European selection processes.
| Section | What you do | Commonly reported |
|---|---|---|
| Inductive reasoning | Two grids share a hidden rule. Pick which of the candidate grids follow the same rule. | About 6 minutes |
| Ability to concentrate | Spot small details accurately, fast, on a simple repeated judgement. | About 2 minutes |
| Spatial orientation | Read a heading indicator and a relative bearing indicator, then work out where you are relative to a beacon. | About 3 minutes |
| Deductive reasoning | A grid where each symbol appears once per row and column. Deduce the missing one. | About 6 minutes |
The deductive section is the one Aon brands gapChallenge, and it is adaptive — the difficulty moves with your performance rather than following a fixed script. The inductive section gets harder as you progress through it.
Each section carries its own bar
This is the detail that changes how you prepare. A strong overall score does not rescue a weak section: candidates are commonly reported to need a minimum mark in each section to advance. One collapse ends the application even if everything else was excellent.
So preparation should be levelling rather than optimising. Find your weakest of the four and spend your time there, however unsatisfying that is compared with getting better at the one you enjoy.
Section by section
Inductive reasoning
Two worked grids are linked by a rule. The rule is usually a transformation — a rotation, with symbols swapped for other symbols on a fixed mapping. Your job is to recover it from the pair, then find which two of the four candidate grids are linked by the same rule.
- Recover the rotation first, then the symbol mapping. Doing both at once is where people stall.
- Early items tend to be pure rotation with the symbols untouched. Later ones move every symbol.
- Check a candidate pair against the rule rather than looking for one that ‘feels’ similar.
Ability to concentrate
Two minutes, a very simple judgement, repeated at speed. There is nothing to work out — the difficulty is entirely in not making careless errors while going fast, and in not slowing down as the seconds run.
- Settle on a rhythm in the first ten seconds and hold it.
- Do not re-check. A second look costs more than the error it prevents at this speed.
- Watch for the near-miss variants — the almost-right item is the whole test.
Spatial orientation
Two instruments tell you where you are. A direction indicator gives your heading; a relative bearing indicator points to a beacon relative to your nose. From those you work out which aircraft is pointing your way and where you sit relative to the beacon.
The step that catches people is the reciprocal: the beacon’s direction from you is not your direction from the beacon. Practise that flip until it is automatic rather than calculated.
Deductive reasoning (gapChallenge)
A grid of symbols where each symbol appears exactly once in every row and once in every column — Sudoku with shapes. One cell holds a question mark, and you deduce what must go there by elimination across its row and column.
- Work the row and the column of the target cell only. Solving the whole grid wastes time you do not have.
- Eliminate rather than search. Ask what cannot go there, not what might.
- Because it is adaptive, a run of hard items means you are doing well. Do not read it as failure and panic.
Practical points
- Sit it on a desktop or laptop, not a phone or tablet.
- It is timed and it runs remotely — sort your connection, browser and a quiet hour first.
- If you are unsuccessful, NAV CANADA publishes a one-year wait before you can reapply.
Try a real item
Written to the same standard as the live tests — same format, same difficulty, and where it matters, the same trap that catches people in the real thing. Pick an answer to see the reasoning.
Concentration
A target letter is named, and it changes on every single item. You decide whether the figure shown is that exact letter with exactly three dots beside it — as fast as you can, for two relentless minutes.
Target letter: R. The figure shows a mirrored R with three dots beside it. Does it match?
Spatial Orientation — Bearings
Read the two instruments, then place yourself relative to the beacon. This is the item type that separates candidates more than any other in the spatial group.
Your heading indicator reads 270°. The bearing needle points 45° to the right of your nose. Where are you in relation to the beacon?
Deductive Reasoning
Deduction by elimination. Each of six shapes appears exactly once in every row and once in every column — a Sudoku with shapes instead of digits.
One cell holds a ?. Its ROW already contains the circle, hexagon, square and star. Its COLUMN already contains the circle, hexagon, square and triangle. Which shape goes in the ?
Logical Reasoning — Grid Rules
Two example grids are linked by a hidden rule — the grid is rotated and each symbol swapped for another. You work out the rule, then pick the two grids from four that are linked by the SAME rule.
Rule-finding under time pressure is what logical thinking means in these batteries. It is visual rather than verbal, which is why it is shown rather than written out here — a static description of a grid transformation is not a sample of it.

Common questions
How long is the NAV CANADA online assessment?
NAV CANADA publishes that it is timed and takes approximately 30 minutes, sat remotely with no travel required.
What sections does the NAV CANADA online test have?
Third-party guides and candidate accounts consistently describe four: inductive reasoning, ability to concentrate, spatial orientation and deductive reasoning. NAV CANADA itself does not publish a section breakdown.
What is the pass mark for the NAV CANADA online assessment?
It is not published. Candidates are commonly reported to need a minimum mark in each section rather than only a good overall score, so a weak section can end an application on its own.
How long before I can reapply if I fail the online assessment?
NAV CANADA publishes a one-year wait after an unsuccessful online assessment.
Can I take the NAV CANADA online assessment on my phone?
It should be sat on a desktop or laptop rather than a phone or tablet.
