Study Notes
- Construct validity is the umbrella for all assessment validation types
- Content validation is necessary for evaluating achievement assessments
- Construct validation determines if assessment results can be interpreted in terms of a given construct or set of constructs
- Two central questions for construct validation are construct representation and construct relevance
- Construct underrepresentation weakens assessment validity
- Construct irrelevant factors reduce assessment validity
- Non-native English speakers may struggle on clinical problem-solving assessments due to unfamiliarity with language or cultural colloquialisms
- Writing skills can be a construct irrelevant factor in clinical problem-solving assessments
- Testwiseness, performance anxiety, and learner motivation can also undermine assessment validity
- A construct is a theoretical construction that cannot be observed directly but can be inferred from performance on an assessment.
