How switchChallenge works
Each task shows an input row of four shapes, a missing code and an output row. You choose the four-digit code, from three options, that turns the input into the output. Aon’s own summary of the test is to identify the right four-digit number sequences for receiving the right result.
There is no fixed number of tasks. Aon tells you to finish as many as you can in six minutes, and its practice guide warns that tasks may get more difficult as you go. Before the timed part you can repeat the practice as often as you like.
How the codes work
Each digit in a code names the input position that fills that slot of the output. So 1-2-3-4 leaves the row unchanged, and 1-3-2-4 swaps the second and third shapes while the first and fourth stay where they are.
On harder tasks, codes are chained across rows: the output of the first code becomes the input to the next, and the missing code sits somewhere in the chain. The logic is the same, applied in sequence.
- Read a code left to right: the first digit says which input shape lands in output slot one.
- Check one output slot at a time against the options, and cross out any option that fails.
- In a chain, work forward from the known rows and back from the final output to isolate the missing step.
How it is scored
Aon has not published how switchChallenge is scored. Its candidate preparation page describes performance tests in general as usually adding points for each correct answer and deducting them for every incorrect answer, and its practice guide asks you to work quickly and accurately.
How our practice version works
Our switchChallenge practice uses the same kind of position codes. Rows hold three or four symbols, chains are one to three codes long with the missing code always last, and you choose from four options. There are 24 tasks on a six-minute clock, and difficulty rises on a fixed ramp of our own, since Aon’s is unpublished.
You can skip a task. A wrong answer costs one mark and a skip costs nothing, following Aon’s general description of performance tests rather than a published switchChallenge rule. Aon’s tasks use four shapes and three options, so our screens are close to the real ones but not identical.
