measurement
consistency of test scores over time
*correlate test scores obtained at one point in time with scores obtained at a later point in time for a group of peole
test-retest
consistency of test scores obtained on two equivalent forms of test measuring same thing
*give two forms of test to group and correlated scores
equivalent forms
the consistency that items measure a single construct
*used to estimate the reliability of the homogeneous test (test that measures one construct) or to estimate reliability of dimensions on multideimensional test
internal consistency
consistency or degree of agreement between two or more judges or raters
interscorer
the appropriateness of the interpretations, inferences, and actions made based on test scores
measurement validity
the empricial evidence and theoretical rationales that support the interpretations and actions that taken on the basis of the score(s) obtained from an assessment procedure
validity evidence
the inquiry process of gathering validity evidence that supports score interpretations or inferences
validation
