This study shows that performance examination results are reliable. Using the multi-facet Rasch model ensures consistent pass-fail decisions for most candidates when data are collected properly.
Area of Science:
- Psychometrics
- Educational Measurement
- Performance Assessment
Background:
- Assessing the reliability of performance examinations is crucial for valid pass-fail decisions.
- Candidate outcomes in performance assessments can be influenced by various factors like examiners and tasks.
- Standardization is key to ensuring consistent and comparable assessment results.
Purpose of the Study:
- To evaluate the reproducibility of pass-fail decisions in performance examinations.
- To demonstrate how the multi-facet Rasch model enhances reliability in performance testing.
- To establish confidence in candidate outcomes through rigorous data collection and analysis.
Main Methods:
- Application of the multi-facet Rasch model to account for examination facets (examiners, tasks, items).
- Standardization of the examination process to collect sufficient candidate data.
- Linking of different facets within the examination to a common criterion.
Main Results:
- The multi-facet Rasch model effectively measures candidates against a single, consistent criterion.
- Standardized data collection and linked facets lead to high confidence in results.
- A high percentage of candidates demonstrate reproducible outcomes.
Conclusions:
- Performance examinations can achieve high reliability in pass-fail decisions.
- The multi-facet Rasch model provides a robust framework for analyzing performance assessment data.
- Properly collected and analyzed data ensure confidence in the reproducibility of candidate performance.

Measures of Intelligence
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...
