Standardised test

A standardized test is a test that is administered and scored in a consistent, or "standard", manner. Standardized tests are designed in such a way that the questions, conditions for administering, scoring procedures, and interpretations are consistent and are administered and scored in a predetermined, standard manner.

Any test in which the same test is given in the same manner to all test takers, and graded in the same manner for everyone, is a standardized test. Standardized tests do not need to be high-stakes tests, time-limited tests, or multiple-choice tests. The questions can be simple or complex. The subject matter among school-age students is frequently academic skills, but a standardized test can be given on nearly any topic, including driving tests, creativity, personality, professional ethics, or other attributes.

The opposite of standardized testing is non-standardized testing, in which either significantly different tests are given to different test takers, or the same test is assigned under significantly different conditions (e.g., one group is permitted far less time to complete the test than the next group) or evaluated differently (e.g., the same answer is counted right for one student, but wrong for another student).

Most everyday quizzes and tests taken by students typically meet the definition of a standardized test: everyone in the class takes the same test, at the same time, under the same circumstances, and all of the students are graded by their teacher in the same way. However, the term standardized test is most commonly used to refer to tests that are given to larger groups, such as a test taken by all adults who wish to acquire a license to have a particular kind of job, or by all students of a certain age.

Standardized tests are perceived as being fairer than non-standardized tests, because everyone gets the same test and the same grading system. This is fairer and more objective than a system in which some students get an easier test and others get a more difficult test. The consistency also permits more reliable comparison of outcomes across all test takers, because everyone is taking the same test. The prevalence of standardized testing in formal education has also been criticized for many reasons, however.

The definition of a standardized test has somewhat changed over time. In 1960, standardized tests were defined as those tests in which the conditions and content were equal for everyone taking the test, regardless of when, where, or by whom the test was given or graded. The purpose of this standardization is to make sure that the scores reliably indicate the abilities or skills being measured, and not other things, such as different instructions about what to do if the test taker does not know the answer to a question.
