Which of the following defines an objective test item?

An objective test item is characterized by having a clear and defined answer, which allows for concrete measurement of knowledge and comprehension in a specific subject area. This type of question is designed to assess whether a candidate knows the correct information, and it typically involves formats such as multiple choice, true/false, or matching, where the responses can be easily graded and are not subject to personal interpretation. The clarity of the answer minimizes ambiguity, ensuring that all test-takers are evaluated based on the same criteria, which is critical for fair assessment in educational and training contexts.
