define psychometric test
A psychometric test is a standardised sample of behaviour which can be described by a numerical scale or category system
what are the purpose of psychometric test
- All candidates are observed in the same standardised situation
- Performance is evaluated objectively against a common yardstick
- The task performed gives an accurate (RELIABLE) measure of a job relevant ability and is a VALID predictor of job success
what does the test produce
An OBJECTIVE SCORE which needs to be set in context i.e, where does the person sit relative to a reference group?
what are the benefits of using a test
- Good tests help make better predictions
- Good tests can be efficient
- What is a good test?
- Reliability (test-retest, internal consistency)
