Standardized Test
A standardized test is any form of test
that (1) 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 (2) 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.
Reform
Following
a wide variety of state and federal laws, policies, and regulations aimed at
improving school and teacher performance, standardized achievement tests have
become an increasingly prominent part of public schooling in the United States.
When focused on reforming schools and improving student achievement,
standardized tests are used in a few primary ways:
- To hold schools and educators accountable for educational results and student performance. In this case, test scores are used as a measure of effectiveness, and low scores may trigger a variety of consequences for schools and teachers. For a more detailed discussion see high-stakes test.
- To evaluate whether students have learned what they are expected to learn, such as whether they have met state learning standards. In this case, test scores are seen as a representative indicator of student achievement.
- To identify gaps in student learning and academic progress. In this case, test scores may be used, along with other information about students, to diagnose learning needs so that educators can provide appropriate services, instruction, or academic support.
- To identify achievement gaps among different student groups, including students of color, students who are not proficient in English, students from low-income households, and students with physical or learning disabilities. In this case, exposing and highlighting achievement gaps may be seen as an essential first step in the effort to educate all students well, which can lead to greater public awareness and changes in educational policies and programs.
- To determine whether educational policies are working as intended. In this case, elected officials and education policy makers may rely on standardized-test results to determine whether their laws and policies are working or not, or to compare educational performance from school to school or state to state. They may also use the results to persuade the public and other elected officials that their policies are in the best interest of children and society.
