Flashcards
Test-retest reliability
Test-retest reliability
How well a test measures the same construct over time. It's like taking the same quiz multiple times, hoping your score stays consistent.
Parallel forms reliability
Parallel forms reliability
A method for estimating how consistently a test measures a skill or trait. Think of it as measuring a ruler against another one to see if they align perfectly.
Criterion-based test
Criterion-based test
A test that compares a person's score to a predefined standard or criteria, rather than comparing it to the scores of others.

- Test Purchaser Competencies: Three levels (A, B, C), associated training, and test types.
- Construct, Convergent, and Concurrent Validity: Definitions and understanding of these types of validity.
- Criterion, Discriminant, and Face Validity: Definitions and distinctions between these types of validity.
- Measurement Error Sources: Identifying sources of error in measurement.
- Kuder-Richardson-20 and Spearman-Brown Formula: Details on these calculation formulas, and their uses.
- Item Response Theory: Definition and description, comparison to classical test construction.
- Scale Types and Norms: Different types of scales and norms, including norm-referenced and criterion-based tests.
- Test Score Theory: Understanding of domain sampling model, error sources, item response theory, test-retest reliability, parallel forms reliability, split-half reliability, KR20 formula, and Cronbach's Alpha, with standard error of measurement calculation.
- Reliability Calculation Methods: Test-retest, parallel forms, split-half, KR20, Cronbach's Alpha, and standard error of measurement. A table showing these methods may be useful.
- Validity Types: In-depth knowledge of construct, convergent, concurrent, criterion, predictive, content, discriminant, and face validity. A table for each type of validity may be beneficial.
