The Standards for Education and Psychological Testing defines test as, “An evaluative device or procedure in which a sample of an examinee’s behavior (is) evaluated and scored using a standardized process” (Hogan, 2007, pg. 38). Anastasi and Cronbach, both traditional textbook authors, define the term test as, “an objective and standardized measure of a sample of behavior” and “a systematic procedure for observing behavior and describing it with the aid of numerical scales or fixed categories” (Hogan, 2007, pg. 38).

Testing samples a person’s behavior, creates a standardized measure, and contributes in making important decisions about the individual taking the test. Testing is used in many different areas and is used to sample a person behavior, create a standardize measure, and contribute in making important decisions. For example, college admissions officers consult test score before admitting or rejecting an applicant. The military uses test scores to aid in qualifying placing soldiers for specific jobs.
