STANDARDIZED TEST

A standardized test is any form of test that requires all test takers to answer the same questions, or a selection of questions from common bank of questions, in the same way, and that is scored in a “standard” or consistent manner, which makes it possible to compare the relative performance of individual students or groups of students. While different types of tests and assessments may be “standardized” in this way, the term is primarily associated with large-scale tests administered to large populations of students, such as a multiple-choice test given to all the eighth-grade public-school students in a particular state, for example.

In addition to the familiar multiple-choice format, standardized tests can include true-false questions, short-answer questions, essay questions, or a mix of question types. While standardized tests were traditionally presented on paper and completed using pencils, and many still are, they are increasingly being administered on computers connected to online programs (for a related discussion, see computer-adaptive test). While standardized tests may come in a variety of forms, multiple-choice and true-false formats are widely used for large-scale testing situations because computers can score them quickly, consistently, and inexpensively. In contrast, open-ended essay questions need to be scored by humans using a common set of guidelines or rubrics to promote consistent evaluations from essay to essay—a less efficient and more time-intensive and costly option that is also considered to be more subjective. (Computerized systems designed to replace human scoring are currently being developed by a variety of companies; while these systems are still in their infancy, they are nevertheless becoming the object of growing national debate.)

While standardized tests are a major source of debate in the United States, many test experts and educators consider them to be a fair and objective method of assessing the academic achievement of students, mainly because the standardized format, coupled with computerized scoring, reduces the potential for favoritism, bias, or subjective evaluations. On the other hand, subjective human judgment enters into the testing process at various stages—e.g., in the selection and presentation of questions, or in the subject matter and phrasing of both questions and answers. Subjectivity also enters into the process when test developers set passing scores—a decision that can affect how many students pass or fail, or how many achieve a level of performance considered to be “proficient.” For more detailed discussions of these issue, see measurement error, test accommodations, test bias and score inflation.

Standardized tests may be used for a wide variety of educational purposes. For example, they may be used to determine a young child’s readiness for kindergarten, identify students who need special-education services or specialized academic support, place students in different academic programs or course levels, or award diplomas and other educational certificates. The following are a few representative examples of the most common forms of standardized test:

Achievement tests are designed to measure the knowledge and skills students learned in school or to determine the academic progress they have made over a period of time. The tests may also be used to evaluate the effectiveness of a schools and teachers, or identify the appropriate academic placement for a student—i.e., what courses or programs may be deemed most suitable, or what forms of academic support they may need. Achievement tests are “backward-looking” in that they measure how well students have learned what they were expected to learn.

Aptitude tests attempt to predict a student’s ability to succeed in an intellectual or physical endeavor by, for example, evaluating mathematical ability, language proficiency, abstract reasoning, motor coordination, or musical talent. Aptitude tests are “forward-looking” in that they typically attempt to forecast or predict how well students will do in a future educational or career setting. Aptitude tests are often a source of debate, since many question their predictive accuracy and value.

College-admissions tests are used in the process of deciding which students will be admitted to a collegiate program. While there is a great deal of debate about the accuracy and utility of college-admissions tests, and many institutions of higher education no longer require applicants to take them, the tests are used as indicators of intellectual and academic potential, and some may consider them predictive of how well an applicant will do in postsecondary program.

  International-comparison tests are administered periodically to representative samples of students in a number of countries, including the United States, for the purposes of monitoring achievement trends in individual countries and comparing educational performance across countries. A few widely used examples of international-comparison tests include the Programme for International Student Assessment (PISA), the Progress in International Reading Literacy Study (PIRLS), and the Trends in International Mathematics and Science Study (TIMSS).

Psychological tests, including IQ tests, are used to measure a person’s cognitive abilities and mental, emotional, developmental, and social characteristics. Trained professionals, such as school psychologists, typically administer the tests, which may require students to perform a series of tasks or solve a set of problems. Psychological tests are often used to identify students with learning disabilities or other special needs that would qualify them for specialized services.
