Assessment and Evaluation of Student Performance
What the exam tests
This domain tests valid, reliable, fair assessment: test blueprints, item types, performance checklists, scoring rubrics, standard setting, remediation, and test security. Instructor II must defend both the score and the process.
Core rules
- Build a test blueprint from objectives so content weighting matches instruction.
- Use written items for knowledge and scored practical checklists for manipulative skills.
- Define the passing standard in advance and apply it consistently.
- Train evaluators and use a rubric to improve inter-rater reliability.
- Analyze items: difficulty is the proportion correct; discrimination compares upper and lower performers.
- Provide remediation and re-testing that match the failed objective.
Worked example
A 30-student quiz includes item 12. Twenty-four students answer correctly, so difficulty is 0.80. In the top 10 scorers, 9 answer correctly; in the bottom 10, 4 do. Discrimination is 0.90 minus 0.40, or 0.50. The item is reasonably difficult and discriminates well, so it is retained. A second item with difficulty 0.95 and discrimination 0.05 is reviewed for ambiguity or triviality. Reasoning: item statistics guide revision, not automatic deletion.
Traps
Teaching only to the test; scoring practicals without a rubric; changing conditions between candidates; using a written test for a manipulative objective; and offering no structured remediation.
