Assessment Strategy
Validation & Reliability Considerations
Evaluate test reliability to insure the application or instrument yields metrics that quantify what you are trying to evaluate. Caveat Emptor, vendors claim their instruments are impartial and unbiased; but there is risk, so proceed carefully with due diligence in reviewing the nearly limitless choices in the market. Because common measures of reliability come from statistical analysis of psychometric data it’s essential to look at what’s being measured like sample size and study population and who did the research and analysis:

ii. Validation is just as important. Find out whether the research and validation processes where conducted by a reputable, impartial, and independent third-party consultant or academic institution.
