Face validity
Appears to measure what it claims to measure
Weakest, insufficient by itself
Informal
Validity
Measures what it says it measures
Content validity
How we’ll content if an assessment represents the attribute being measured
Usually based on expert judgement, research, and theory
Criterion validity
Concurrent
Predictive
Concurrent validity
Instrument yields scores similar to scores obtained from a known assessment
Predictive validity
How well assessment predicts future performance
Known groups method for construct validity
Identify groups of people who differ on the characteristic being measured
Administer the assessment to that group of people
T scores should reflect differences
Convergent/divergent methods
Convergent-measurements of similar traits should be correlated
Divergence- different traits should be unrelated
