FAA Fundamentals of Instructing (FOI)The Teaching Process and MethodsHard
A private pilot knowledge test intended to measure understanding of weather theory instead relies on overly complex sentence structure, causing many applicants to answer incorrectly due to reading difficulty rather than lack of weather knowledge. This test is deficient in which characteristic of a well-designed evaluation instrument?
- AObjectivity
- BUsability
- CValidity
- DReliability
Show answer & explanationAnswer & explanation
Correct answer: C. Validity
Validity means a test actually measures what it is intended to measure; because the test is measuring reading comprehension rather than weather knowledge, it lacks validity even if it might otherwise be reliable or easy to use.
Why the other options are wrong
- A. Objectivity refers to freedom from subjective grading bias, unrelated to reading complexity.
- B. Usability concerns practicality of administering the test, not what the test actually measures.
- D. Reliability refers to consistency of results, not whether the test measures the right thing.
Validity (Test Characteristic)
The extent to which a test measures what it is actually intended to measure, a key characteristic of a well-designed evaluation instrument.
- A test can be reliable but still invalid
- Confounding factors (like reading difficulty) reduce validity
- Validity is essential for fair and accurate assessment
