What should be done if a test item is found to have a high difficulty index (close to 1.0) and a low discrimination index?

0
A) Use it for diagnostic assessment only.
B) Discard or revise the item as it is too easy.
C) Retain the item as it is ideal.
D) Convert it to an essay question.

Correct Answer: B) Discard or revise the item as it is too easy.

A P-value near 1.0 means almost everyone got it right (too easy), making it unable to discriminate between high and low achievers (low D). Such items waste time and should be revised or removed.
