traditional views of validity
a test is valid if it measures what it is designed to measure
a test can measure exactly what it was designed to measure and yet not be valid if the inferences that are made from the test scores are not supportable
e.g. making a hiring decision based on a personality test

traditional views of validity
current views of validity
view validity as a unitary or single concept
importance of evaluating the interpretation of test scores and then agree to which the accumulated evidence supports the intended interpretation of test scores for the proposed use

What are the five sources of evidence of validity currently recognized by the Standards?
- evidence based on test content
- evidence based on response processes
- evidenced based on internal structure
- evidence based on relations with other variables
- evidence based on the consequences of testing
- evidence based on test content
Previously referred to as content validity, this source of validity evidence involves logically examining and evaluating the content of a test (including the test questions, format, wording, and tasks required of test takers) to determine the extent to which the content is representative of the concepts that the test is designed to measure without either underrepresenting those concepts or including elements that are irrelevant to their measurement.

- evidence based on test content
- evidence based on response processes
bserving test takers as they respond to the test and/or interviewing them when they complete the test

- evidence based on response processes
- evidenced based on internal structure
focuses on whether the conceptual framework used in test development could be demonstrated using appropriate analytical techniques
e.g. if a test was designed to measure a single concept (such as anxiety), we would analyze the test results to find out how many underlying concepts account for the variations in test taker scores.

- evidenced based on internal structure
- evidence based on relations with other variables
criterion-related validity
correlating test scores with other measures to determine whether those scores are related to other measures to which we would expect them to relate

- evidence based on relations with other variables
- evidence based on the consequences of testing
intended and unintended consequences may occur
if the test is biased, an unintended consequence might be that test scores appear to favor one group over another. However, it is also important to understand that just because different groups score differently on a test does not automatically mean that the test is biased
