Explain the importance of conducting a pilot test. Give examples of what can happen when the test developer does not conduct a pilot test.
What will be an ideal response?
• When developers design a new test, they cannot assume that the test will perform as expected.
• The pilot test is a scientific investigation of evidence that suggests that the test scores are reliable and valid for their specified purpose
• The test developers then revise the test to fix any problems with the test’s performance.
• It is improper to rely on the results of a psychological test that has not been studied to ensure that its data are valid and reliable—that is, that the results are consistent and that the inferences that are will be made from the scores on the test are appropriate.
• If the pilot test is not conducted, poor items may be retained in the test. This will reduce the reliability and validity of the test.
