Fault Finding Test
Ability test · Fault diagnosis
Pinpoint candidates who can trace a fault logically through a system
Candidates use a grid showing what each switch does to work out which switch in a sequence is faulty, or that there is no fault. The report gives the candidate's score and time taken, to support a recruitment decision.


What the Fault Finding Test measures
The Fault Finding Test, also known as a fault diagnosis test, measures the ability to diagnose faults in electrical and mechanical systems. Candidates work out how inputs are changed by a series of switches and which switch is not working.
Following a system
Tracking how each switch changes the inputs.
Diagnosing faults
Working out which switch has no effect.
Precision and concentration
Staying accurate as the switches combine.
Why organisations choose Viewpoint ability tests
Fair and objective
Every candidate takes the same test, scored the same way, so decisions rest on evidence rather than impressions.
Candidates know what to expect
Clear instructions and example questions come before the test starts, so nobody is caught out by the format.
Reports you can act on
Clear results and score bands from Very Low to Very High, ready for shortlisting or a feedback conversation.
Fits your process
Use it to screen applicants early, to shortlist, or to add objective evidence at the final stage.
Reports that do the work for you
The report gives the candidate's score and the time they took to complete the test, to support a recruitment decision.

Who it’s for
The test is particularly useful in jobs that need precision and a strong technical understanding. Typical roles.
Technical recruitment
Assess the systematic diagnosis electricians, engineers and data analysts rely on.
Maintenance and operations
Find site operatives and mechanics who work precisely through a system to find faults.
Armed forces roles
Measure precision, concentration and technical understanding for service roles.

Candidates read the instructions and try example questions before the test starts.
- 3
Get the results
Results are ready as soon as the candidate finishes. Download the report and use it straight away.
At a glance
- 25 questions, completed in 20 minutes
- 7 switches are used across the test; each question uses 3
- A grid shows what each switch does; a faulty switch has no effect
- Candidates identify the faulty switch, or that there is no fault

Learn the switch grid first
It doesn't change during the test, so time spent on it early pays off.
Count the changes
Work out how many switches should flip each input; an even number means no change.
Don't be fooled by no visible change
No change can mean a working circuit or a fault, so always check.
