Understand what a test claims to measure
Course overview · 4 min reading + 12 min practice, estimated
Principles and method
A psychometric instrument may assess a defined ability, preference or other construct. Start with the purpose and the decision the result will inform. A label such as scientific does not establish suitability for a particular role. Ask what the construct means, how items relate to it and what evidence supports the intended use. Personality preferences should not be casually interpreted as ability or moral character. This course teaches evaluation questions, not qualification to administer or interpret restricted instruments. Use appropriately qualified practitioners where required by the instrument and context.
Worked example
A supplier markets a personality profile as a way to identify the best salespeople. The buyer asks for evidence supporting that specific selection use rather than assuming a development tool is valid for hiring.
Put it into practice
Write a purpose statement and five questions for a fictional test supplier.
Use fictional information and keep your work in your own notes.
Compare your approach: self-review guidance
Distinguish development, selection and team discussion uses. Ask what conclusions the instrument does not support. Avoid equating a branded report with an independently validated hiring recommendation.
