One way to measure the effectiveness of an assessment is to compare the assessment results with the annual performance reviews of those previously assessed. Usually, if someone is performing below standard, your assessment results could indicate the reason. By comparing an individual's annual review to the original assessment, you can also determine if the users of the system are properly interpreting the assessment when they make their hiring decisions. Remember, it is very possible to hire a good applicant, but not using the training components of the assessment may result in the individual not performing up to their potential.
