Which statistical index BEST indicates an item's ability to distinguish between high- and low-performing examinees?
Answer: Item discrimination index (D)
The discrimination index (D) measures the difference in correct-response rates between upper and lower scoring groups, reflecting how well an item separates examinees.
The 'halo effect' in performance assessment refers to:
Answer: A rater's overall impression of an examinee influencing ratings on specific dimensions
The halo effect is a cognitive bias where a rater's global perception of a person skews ratings on individual performance dimensions.
A test administrator who reviews test content outside of their official role and shares it with examinees is PRIMARILY violating:
Answer: Test security and confidentiality policies
Sharing secure test content breaches the confidentiality and security agreements that administrators are required to uphold.
A formative assessment differs from a summative assessment in that it is PRIMARILY used to:
Answer: Monitor learning progress and guide instruction during the learning process
Formative assessments provide ongoing feedback to improve learning, whereas summative assessments evaluate cumulative achievement at the end of instruction.

Answer: Item difficulty (location on the ability scale where the item provides most information)
The 'b' parameter in IRT represents item difficulty, specifically the point on the ability scale where an examinee has a 50% chance of answering correctly (in 1PL/2PL models).
Chain-of-custody procedures for test materials are designed PRIMARILY to:
Answer: Document and track the handling of secure materials to prevent compromise
