Choose the most appropriate answer from the options given below:

Correct option is C

The length of a classroom test will primarily vary based on the purpose of the test, the kinds of items used, the age and ability of the pupils tested, and (E) the instructional objective tested. These factors determine how long a test needs to be to effectively measure students’ understanding and abilities.
Information Booster: · Purpose of the test: If the test is for formative assessment, it may be shorter; summative assessments tend to be longer.
· Kinds of items used: Multiple-choice questions take less time to answer than essays, which affect the test length.
· Age and ability of pupils: Younger students or students with lower ability may need shorter tests for better engagement.
· Instructional objectives: A test should align with what is being taught, and longer tests are needed to assess complex objectives.
Additional Knowledge:
Knowledge of the subject teacher refers to the teacher's understanding of the subject matter they are teaching. While important for crafting the content and quality of the test, it does not directly influence the length of the test.
