Validity & Reliability

  • Validity means a test or tool measures what it’s supposed to measure. For example, a math test should measure math skills, not reading ability.
  • Reliability means a test or tool gives consistent results. For example, if you take the same test twice, you should get similar scores.

In short, validity is about accuracy, and reliability is about consistency.
