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 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. A standardized test may be any type of test: a written test, an oral test, or a practical skills performance test. 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, athleticism, 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 during school 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. Most standardized tests are forms of summative assessments - assessments that attempt to measure the learning of the participants at the end of an instructional unit.

Because everyone gets the same test and the same grading system, standardized tests are often perceived as being fairer than non-standardized tests. Such tests are often thought of as fairer and more objective than a system in which some students get an easier test and others get a more difficult test. Standardized tests are designed to permit reliable comparison of outcomes across all test takers, because everyone is taking the same test. However, both testing in general and standardized testing in specific are criticized by some people. For example, some people believe that it is unfair to ask all students the same questions, if some students' schools did not have the same learning standards.

Definition

The definition of a standardized test has changed somewhat over time. In 1960, standardized tests were defined as those 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.

By the beginning of the 21st century, the focus shifted away from a strict sameness of conditions towards equal fairness of conditions. For example, a test taker with a broken wrist might write more slowly because of the injury, and it would be more equitable, and produce a more reliable understanding of the test taker's actual knowledge, if that person were given a few more minutes to write down the answers to a time-limited test. Changing the testing conditions in a way that improves fairness with respect to a permanent or temporary disability, but without undermining the main point of the assessment, is called accommodation. However, if the purpose of the test were to see how quickly the student could write, then giving the test taker extra time would become a modification of the content, and no longer a standardized test.

History

China

The earliest evidence of standardized testing was in China, during the Han Dynasty, where the imperial examinations covered the Six Arts which included music, archery, horsemanship, arithmetic, writing, and knowledge of the rituals and ceremonies of both public and private parts. These exams were used to select employees for the state bureaucracy.

Later, sections on military strategies, civil law, revenue and taxation, agriculture and geography were added to the testing. In this form, the examinations were institutionalized for more than a millennium.

Today, standardized testing remains widely used, most famously in the Gaokao system.

UK

Standardized testing was introduced into Europe in the early 19th century, modeled on the Chinese mandarin examinations, through the advocacy of British colonial administrators, the most "persistent" of which was Britain's consul in Guangzhou, China, Thomas Taylor Meadows. Meadows warned of the collapse of the British Empire if standardized testing was not implemented throughout the empire immediately.

Prior to their adoption, standardized testing was not traditionally a part of Western pedagogy. Based on the skeptical and open-ended tradition of debate inherited from Ancient Greece, Western academia favored non-standardized assessments using essays written by students. It is because of this, that the first European implementation of standardized testing did not occur in Europe proper, but in British India.Kazin, Edwards, and Rothman (2010), 142. Inspired by the Chinese use of standardized testing, in the early 19th century, British "company managers hired and promoted employees based on competitive examinations in order to prevent corruption and favoritism." This practice of standardized testing was later adopted in the late 19th century by the British mainland. The parliamentary debates that ensued made many references to the "Chinese mandarin system".Mark and Boyer (1996), 9–10.

It was from Britain that standardized testing spread, not only throughout the British Commonwealth, but to Europe and then America. Its spread was fueled by the Industrial Revolution. The increase in number of school students during and after the Industrial Revolution, as a result of compulsory education laws, decreased the use of open-ended assessment, which was harder to mass-produce and assess objectively due to its intrinsically subjective nature.

Standardized tests such as the War Office Selection Boards were developed for the British Army during the Second World War to choose candidates for officer training and other tasks. The tests looked at soldiers' mental abilities, mechanical skills, ability to work with others, and other qualities. Previous methods had suffered from bias and resulted in choosing the wrong soldiers for officer training.

United States

Standardized testing has been a part of American education since the 19th century, but the widespread reliance on standardized testing in schools in the US is largely a 20th-century phenomenon.

Immigration in the mid-19th century contributed to the growth of standardized tests in the United States. Standardized tests were used when people first entered the US to test social roles and find social power and status.

The College Entrance Examination Board did not offer standardized testing for university and college admission until 1900. Their first examinations were administered in 1901, in nine subjects. This test was implemented with the idea of creating standardized admissions for the United States in northeastern elite universities. Originally, the test was also meant for top boarding schools, in order to standardize curriculum. Originally the standardized test was made of essays and was not intended for widespread testing.

During World War I, the Army Alpha and Beta tests were developed to help place new recruits in appropriate assignments based upon their assessed intelligence levels. The first edition of a modern standardized test for IQ, the Stanford–Binet Intelligence Test, appeared in 1916. The College Board then designed the SAT (Scholar Aptitude Test) in 1926. The first SAT test was based on the Army IQ tests, with the goal of determining the test taker's intelligence, problem-solving skills, and critical thinking. In 1959, Everett Lindquist offered the ACT (American College Testing) for the first time. As of 2020, the ACT includes four main sections with multiple-choice questions to test English, mathematics, reading, and science, plus an optional writing section.

Individual states began testing large numbers of children and teenagers through the public school systems in the 1970s. By the 1980s, American schools were assessing nationally. In 2012, 45 states paid an average of $27 per student, and $669 million overall, on large-scale annual academic tests. However, other costs, such as paying teachers to prepare students for the tests and for class time spent administering the tests, significantly exceeds the cost of the test itself.

The need for the federal government to make meaningful comparisons across a highly de-centralized (locally controlled) public education system has encouraged the use of large-scale standardized testing. The Elementary and Secondary Education Act of 1965 required some standardized testing in public schools. The No Child Left Behind Act of 2001 further tied some types of public school funding to the results of standardized testing.

The goal of No Child Left Behind was to improve the education system in the United States by holding schools and teachers accountable for student achievement, including the educational achievement gap between minority and non-minority children in public schools. An additional factor in the United States education system is the socioeconomic background of the students being tested. According to the National Center for Children in Poverty, 41 percent of children under the age of 18 come from lower-income families. These students require specialized attention to perform well in school and on the standardized tests.

Under these federal laws, the school curriculum was still set by each state, but the federal government required states to assess how well schools and teachers were teaching the state-chosen material with standardized tests. Students' results on large-scale standardized tests were used to allocate funds and other resources to schools, and to close poorly performing schools. The Every Student Succeeds Act replaced the NCLB at the end of 2015. By that point, these large-scale standardized tests had become controversial in the United States because they were high-stakes tests for the school systems and teachers.

While in recent years, many universities and colleges have abandoned the requirement of standardized test scores by applicants.

Australia

The Australian National Assessment Program – Literacy and Numeracy (NAPLAN) standardized testing was commenced in 2008 by the Australian Curriculum, Assessment and Reporting Authority, an independent authority "responsible for the development of a national curriculum, a national assessment program and a national data collection and reporting program that supports 21st century learning for all Australian students".

The testing includes all students in Years 3, 5, 7 and 9 in Australian schools to be assessed using national tests. The subjects covered in these testings include Reading, Writing, Language Conventions (Spelling, Grammar and Punctuation) and Numeracy.

The program presents students level reports designed to enable parents to see their child's progress over the course of their schooling life, and help teachers to improve individual learning opportunities for their students. Students and school level data are also provided to the appropriate school system on the understanding that they can be used to target specific supports and resources to schools that need them most. Teachers and schools use this information, in conjunction with other information, to determine how well their students are performing and to identify any areas of need requiring assistance.

The concept of testing student achievement is not new, although the current Australian approach may be said to have its origins in current educational policy structures in both the US and the UK. There are several key differences between the Australian NAPLAN and the UK and USA strategies. Schools that are found to be under-performing in the Australian context will be offered financial assistance under the current federal government policy.

Colombia

In 1968 the Colombian Institute for the evaluation of education - ICFES was born to regulate higher education. The previous public evaluation system for the authorization of operation and legal recognition for institutions and university programs was implemented.

Colombia has several standardized tests that assess the level of education in the country. These exams are performed by the ICFES.

Students in third grade, fifth grade and ninth grade take the "Saber 3°5°9°" exam. This test is currently presented on a computer in controlled and census samples.

Upon leaving high school students present the "Saber 11" that allows them to enter different universities in the country. Students studying at home can take this exam to graduate from high school and get their degree certificate and diploma.

Students leaving university must take the "Saber Pro" exam.

Canada

Canada leaves education, and standardized testing as result, under the jurisdiction of the provinces. Each province has its own province-wide standardized testing regime, ranging from no required standardized tests for students in Ontario to exams worth 50% of final high school grades in Newfoundland and Labrador.

Design and scoring

Design

Most commonly, a major academic test includes both human-scored and computer-scored sections.

A standardized test can be composed of multiple-choice questions, true-false questions, essay questions, authentic assessments, or nearly any other form of assessment. Multiple-choice and true-false items are often chosen for tests that are taken by thousands of people because they can be given and scored inexpensively, quickly, and reliably through using special answer sheets that can be read by a computer or via computer-adaptive testing. Some standardized tests have short-answer or essay writing components that are assigned a score by independent evaluators who use rubrics (rules or guidelines) and benchmark papers (examples of papers for each possible score) to determine the grade to be given to a response.

Any subject matter

Not all standardized tests involve answering questions. An authentic assessment for athletic skills could take the form of running for a set amount of time or dribbling a ball for a certain distance. Healthcare professionals must pass tests proving that they can perform medical procedures. Candidates for driver's licenses must pass a standardized test showing that they can drive a car. The Canadian Standardized Test of Fitness has been used in medical research, to determine how physically fit the test takers are.

Machine and human scoring

Since the latter part of the 20th century, large-scale standardized testing has been shaped in part, by the ease and low cost of grading of multiple-choice tests by computer. Most national and international assessments are not fully evaluated by people.

People are used to score items that are not able to be scored easily by computer (such as essays). For example, the Graduate Record Exam is a computer-adaptive assessment that requires no scoring by people except for the writing portion.

Human scoring is relatively expensive and often variable, which is why computer scoring is preferred when feasible. For example, some critics say that poorly paid employees will score tests badly.Houtz, Jolayne (August 27, 2000
"Temps spend just minutes to score state test A WASL math problem may take 20 seconds; an essay, 2 minutes"
''Seattle Times'' "In a matter of minutes, a $10-an-hour temp assigns a score to your child's test" Agreement between scorers can vary between 60 and 85 percent, depending on the test and the scoring session. For large-scale tests in schools, some test-givers pay to have two or more scorers read each paper; if their scores do not agree, then the paper is passed to additional scorers.

Though the process is more difficult than grading multiple-choice tests electronically, essays can also be graded by computer. In other instances, essays and other open-ended responses are graded according to a pre-determined assessment rubric by trained graders. For example, at Pearson, all essay graders have four-year university degrees, and a majority are current or former classroom teachers.

Use of rubrics for fairness

Using a rubric is meant to increase fairness when the student's performance is evaluated. In standardized testing, measurement error (a consistent pattern of errors and biases in scoring the test) is easy to determine in standardized testing. In non-standardized assessment, graders have more individual discretion and therefore are more likely to produce unfair results through unconscious bias. When the score depends upon the graders' individual preferences, then students' grades depend upon who grades the test. Standardized tests also remove teacher bias in assessment. Research shows that teachers create a kind of self-fulfilling prophecy in their assessment of students, granting those they anticipate will achieve with higher scores and giving those who they expect to fail lower grades.

Using scores for comparisons

There are two types of standardized test score interpretations: a norm-referenced score interpretation or a criterion-referenced score interpretation.
* Norm-referenced score interpretations compare test-takers to a sample of peers. The goal is to rank students as being better or worse than other students. Norm-referenced test score interpretations are associated with traditional education. Students who perform better than others pass the test, and students who perform worse than others fail the test.
* Criterion-referenced score interpretations compare test-takers to a criterion (a formal definition of content), regardless of the scores of other examinees. These may also be described as standards-based assessments, as they are aligned with the standards-based education reform movement. Criterion-referenced score interpretations are concerned solely with whether or not this particular student's answer is correct and complete. Under criterion-referenced systems, it is possible for all students to pass the test, or for all students to fail the test.

Either of these systems can be used in standardized testing. What is important to standardized testing is whether all students are asked equivalent questions, under equivalent circumstances, and graded equally. In a standardized test, if a given answer is correct for one student, it is correct for all students. Graders do not accept an answer as good enough for one student but reject the same answer as inadequate for another student.

The term ''normative assessment'' refers to the process of comparing one test-taker to his or her peers. A norm-referenced test (NRT) is a type of test, assessment, or evaluation which yields an estimate of the position of the tested individual in a predefined population. The estimate is derived from the analysis of test scores and other relevant data from a sample drawn from the population. This type of test identifies whether the test taker performed better or worse than other students taking this test. A criterion-referenced test (CRT) is a style of test which uses test scores to show whether or not test takers performed well on a given task, not how well they performed compared to other test takers. Most tests and quizzes that are written by school teachers are criterion-referenced tests. In this case, the objective is simply to see whether the student can answer the questions correctly. The teacher is not usually trying to compare each student's result against other students.

This makes standardized tests useful for admissions purposes in higher education, where a school is trying to compare students from across the nation or across the world. Examples of such international benchmark tests include the Trends in International Mathematics and Science Study ( TIMMS) and the Progress in International Reading Literacy Study (PIRLS). Performance on these exams have been speculated to change based on the way standards like the Common Core State Standards (CCSS) line up with top countries across the world.

Because the results can be compared across dissimilar schools, the results of a national standardized test can be used to determine what areas need to be improved. Tests that are taken by everyone can help the government determine which schools and which students are struggling the most. With this information, they can implement solutions to fix the issue, allowing students to learn and grow in an academic environment.

Standards

The considerations of validity and reliability typically are viewed as essential elements for determining the quality of any standardized test. However, professional and practitioner associations frequently have placed these concerns within broader contexts when developing standards and making overall judgments about the quality of any standardized test as a whole within a given context.

Evaluation standards

In the field of evaluation, and in particular educational evaluation, the Joint Committee on Standards for Educational Evaluation has published three sets of standards for evaluations. ''The Personnel Evaluation Standards'' was published in 1988, ''The Program Evaluation Standards'' (2nd edition) was published in 1994, and ''The Student Evaluation Standards'' was published in 2003.

Each publication presents and elaborates a set of standards for use in a variety of educational settings. The standards provide guidelines for designing, implementing, assessing and improving the identified form of evaluation. Each of the standards has been placed in one of four fundamental categories to promote educational evaluations that are proper, useful, feasible, and accurate. In these sets of standards, validity and reliability considerations are covered under the accuracy topic. The tests are aimed at ensuring that student evaluations will provide sound, accurate, and credible information about student learning and performance, however; standardized tests offer narrow information on many forms of intelligence and relying on them harms students because they inaccurately measure a student's potential for success.

Testing standards

In the field of psychometrics, the ''Standards for Educational and Psychological Testing'' place standards about validity and reliability, along with errors of measurement and issues related to the accommodation of individuals with disabilities. The third and final major topic covers standards related to testing applications, credentialing, plus testing in program evaluation and public policy.

Statistical validity

One of the main advantages of standardized testing is that the results can be empirically documented; therefore, the test scores can be shown to have a relative degree of validity and reliability, as well as results which are generalizable and replicable. This is often contrasted with grades on a school transcript, which are assigned by individual teachers. It may be difficult to account for differences in educational culture across schools, difficulty of a given teacher's curriculum, differences in teaching style, and techniques and biases that affect grading.

Another advantage is aggregation. A well designed standardized test provides an assessment of an individual's mastery of a domain of knowledge or skill which at some level of aggregation will provide useful information. That is, while individual assessments may not be accurate enough for practical purposes, the mean scores of classes, schools, branches of a company, or other groups may well provide useful information because of the reduction of error accomplished by increasing the sample size.

Test takers

There is criticism from students themselves that tests, while standardized, are unfair to the individual student. Some students are "bad test takers", meaning they get nervous and unfocused on tests. Therefore, while the test is standard and should provide fair results, the test takers are at a disadvantage, but have no way to prove their knowledge otherwise, as there is no other testing alternative that allows students to prove their knowledge and problem-solving skills.

Some students have test anxiety. Between ten to forty percent of students experience this type of anxiety. In fact, the children of poverty are struck most with testing anxiety. Testing anxiety applies to standardized tests as well, where students who may not have test anxiety regularly feel immense pressure to perform when the stakes are so high. High-stakes standardized testing includes exams like the SAT, the PARCC, and the ACT, where doing well is required for grade passing or college admission.

Annual standardized tests at school

Standardized testing is a very common way of determining a student's past academic achievement and future potential. However, high-stakes tests (whether standardized or non-standardized) can cause anxiety. When teachers or schools are rewarded for better performance on tests, then those rewards encourage teachers to "teach to the test" instead of providing a rich and broad curriculum. In 2007 a qualitative study done by Au Wayne demonstrated that standardized testing narrows the curriculum and encourages teacher-centered instruction instead of student-centered learning.

The validity, quality, or use of tests, particularly annual standardized tests common in education have continued to be widely both supported or criticized. Like the tests themselves, supports and criticisms of tests are often varied and may come from a variety of sources such as parents, test takers, instructors, business groups, universities, or governmental watchdogs.

Supporters of large-scale standardized tests in education often provide the following reasons for promoting testing in education:

* Feedback or diagnosis of test taker's performance
* Fair and efficient
* Promotes accountability
* Prediction and selection
* Improves performance

Critics of standardized tests in education often provide the following reasons for revising or removing standardized tests in education:

* Narrows curricular format and encourages teaching to the test.
* Poor predictive quality.
* Grade inflation of test scores or grades.
* Culturally or socioeconomically biased.Coughlan, Sean
