A test which is scored according to strict rules, rather than on the subjective judgment of the tester. The scorer usually operates to a marking system based on predetermined acceptable answers. Often the test will be scored by someone other than the person who gave it, for even greater objectivity.
Objective tests are different from obtrusive tests, because objective tests are not projective in nature. Projective tests are based on Freudian Psychology (Psychoanalysis) and seek to expose the unconscious perceptions of people.
An objective test is built by following a rigorous protocol which includes the following steps:
Making decisions on nature, goal, target population, power. Detecting which questions are better in terms of discrimination, clarity, ease of response, upon application on a pilot sample. Use appropriate statistical procedures to establish norms for the test.
