Definition
The consistency of a measurement under relevant conditions.
How should you use this idea?
A reliable score is not necessarily a useful measure of the job requirement. Reliability and validity answer different questions.
Put it in context
Start with the specific decision you are making, the skill the job requires and the limitations of your evidence. Document your interpretation and give candidates a consistent process.
For legal or regulatory conclusions, obtain qualified advice for your location and circumstances. A glossary definition cannot resolve those questions.
