# Standardized 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.
A standardized test is administered and scored uniformly for all test takers. 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, multiple-choice tests, academic tests, or tests given to large numbers of test takers. Standardized tests can take various forms, including written, oral, or practical test. The standardized test may evaluate many subjects, including driving, creativity, athleticism, personality, professional ethics, as well as academic skills.
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 or evaluated differently.
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 tests 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 get a particular job, or by all students of a certain age. Most standardized tests are summative assessments (assessments that 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 more objective than a system in which some test takers 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 and being graded the same way.

## 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. Standardized tests have a consistent, uniform method for scoring. This means that all test takers who answer a test question in the same way will get the same score for that question. The purpose of this standardization is to make sure that the scores reliably indicate the abilities or skills being measured, and not other variables.
By the beginning of the 21st century, the focus shifted away from a strict sameness of conditions towards equal fairness of testing 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 an accommodation. However, if the accommodation undermines the purpose of the test, then the allowances would become a modification of the content, and no longer a standardized test.
Examples of standardized and non-standardized tests :
| Subject | Format | Standardized test | Non-standardized test |
| History | Oral | Each student is given the same questions, and their answers are scored in the same way. | The teacher asks each student a different question. Some questions are harder than others. |
| Driving | Practical skills | Each driving student is asked to do the same things, and they are all evaluated by the same standards. | Some driving students have to drive on a highway, but others only have to drive slowly around the block. One examiner takes points off for "bad attitude", but other examiners do not. |
| Mathematics | Written | Each student is given the same questions, and their answers are scored in the same way. | The teacher gives different questions to different students: an easy test for poor students, another test for most students, and a difficult test for the best students. |
| Music | Audition | All musicians play the same piece of music. The judges agreed in advance how much factors such as timing, expression, and musicality count for. | Each musician chooses a different piece of music to play. Judges choose the musician they like best. One judge gives extra points to musicians who wear a costume. |

## 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 notably 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. Because of this, the first European implementation of standardized testing did not occur in Europe proper, but in British India. Inspired by the Chinese use of standardized testing, in the early 19th century, British company managers used standardized exams for hiring and promotions to keep the process fair and free from corruption or favoritism. This practice of standardized testing was later adopted in the late 19th century in the Britain mainland. The parliamentary debates that ensued made many references to the "Chinese mandarin system".
Standardized testing spread from Britain not only throughout the British Commonwealth, but to Europe and then America. Its spread was fueled by the Industrial Revolution, where the increase in number of school students as a result of compulsory education laws decreased the use of open-ended assessments, which were harder to mass-produce and assess objectively.
Standardized tests such as the War Office Selection Boards were developed for the British Army during World War II 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 United States 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 began offering standardized testing for university and college admission in 1901, covering 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 align the curriculum between schools. 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, indirect costs, such as paying teachers to prepare students for the tests and for class time spent administering the tests, significantly exceed the direct 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 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. 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. The results of 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 not necessarily because all the students were taking the same tests and being scored the same way, but because they had become high-stakes tests for the school systems and teachers.
In recent years, many US 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 tests 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 Saskatchewan to exams worth 40% 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. 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 test taker'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. When the score depends upon the graders' individual preferences, then test takers' grades depend upon who grades the test.
Standardized tests also remove grader bias in assessment. Research shows that teachers create a kind of self-fulfilling prophecy in their assessment of test takers, granting those they anticipate will achieve with higher scores and giving those who they expect to fail lower grades. In non-standardized assessment, graders have more individual discretion and therefore are more likely to produce unfair results through unconscious bias.
Sample scoring for the open-ended history question: What caused World War II? :
| Student answers | Standardized grading | Non-standardized grading |
| | Grading rubric: Answers must be marked correct if they mention at least one of the following: Germany's invasion of Poland, Japan's invasion of China, or economic issues. | No grading standards. Each teacher grades however he or she wants to, considering whatever factors the teacher chooses, such as the answer, the amount of effort, the student's academic background, language ability, or attitude. |
| Student #1: WWII was caused by Hitler and Germany invading Poland in 1939. | Teacher #1: This answer mentions one of the required items, so it is correct. Teacher #2: This answer is correct. | Teacher #1: I feel like this answer is good enough, so I'll mark it correct. Teacher #2: This answer is correct, but this good student should be able to do better than that, so I'll only give partial credit. |
| Student #2: WWII was caused by multiple factors, including the Great Depression and the general economic situation, the rise of national socialism, fascism, and imperialist expansionism, and unresolved resentments related to WWI. The war in Europe began with the German invasion of Poland. | Teacher #1: This answer mentions one of the required items, so it is correct. Teacher #2: This answer is correct. | Teacher #1: I feel like this answer is correct and complete, so I'll give full credit. Teacher #2: This answer is correct, so I'll give full points. |
| Student #3: WWII was caused by the assassination of Archduke Ferdinand in 1914. | Teacher #1: This answer does not mention any of the required items. No points. Teacher #2: This answer is wrong. No credit. | Teacher #1: This answer is wrong. No points. Teacher #2: This answer is wrong, but this student tried hard and the sentence is grammatically correct, so I'll give one point for effort. |

### Using scores for comparisons

There are two types of 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 test takers as being better or worse than others. Norm-referenced test score interpretations are associated with traditional education. People who perform better than others pass the test, and people 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 test takers to pass the test, or for all test takers 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 the equivalent questions, under reasonably equal circumstances, and graded according to the same standards.
A normative assessment compares each test taker against other test takers. 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 people taking this test. An IQ test is a norm-referenced standardized test.
Comparing against others makes norm-referenced 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. The standardization ensures that all of the students are being tested equally, and the norm-referencing identifies which are better or worse. 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).
A criterion-referenced test (CRT) is a style of test which uses test scores to show how well test takers performed 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 test taker can answer the questions correctly. The test giver is not usually trying to compare each person's result against other test takers.

## 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 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.
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 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 meant to provide sound, accurate, and credible information about learning and performance; however, most academic tests (standardized or not) offer narrow information of achievement. Relying on a narrow, academic-focused view achievement does not fully represent a person's potential for success (e.g., by not testing interpersonal skills or soft skills).

### Statistical validity

One of the main advantages of larger-scale 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. When looking at individually assigned grades, it may be difficult to account for differences in educational culture across schools, the difficulty of a given teacher's assignments, differences in teaching style, the pressure for grade inflation, and other 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.

## Annual standardized tests at school

Standardized testing is a very common way of determining a student's past academic achievement and future potential.
The CBSE Class 10 AISSE and Class 12 AISSCE Exam or Commonly Referred as "Board Exam" are the one of the Largest Standardized examinations Around 4-5 Million Students Attempt it every Year much more than SAT exam or Similar as Chinese Gaokao Examination.
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: Standardized tests allow teachers to see how their students are performing compared to others in the country. This will help them revise their teaching methods if necessary to help their students meet the standards. Students are given the opportunity to reflect on their scores and see where their strengths as well as weaknesses are. The scores can allow parents to get an idea about how their child is doing academically.
* Fair and efficient. Each test taker will have the same amount of time to complete the test. Every answer and overall grade for a standardized test is evaluated identically, therefore reducing potential bias in the scoring system.
* Promotes accountability: Standardized testing is used as a public policy strategy to establish stronger accountability measures for public education. The idea behind the standardized testing policy movement is that testing is the first step to improving schools, teaching practice, and educational methods through data collection. Proponents argue that the data generated by the standardized tests act like a report card for the community, demonstrating how well local schools are performing. Critics of the movement, however, point to various discrepancies that result from current state standardized testing practices, including problems with test validity and reliability and false correlations (see Simpson's paradox).
* Prediction and selection
* Improves performance
Critics of standardized tests in education often provide the following reasons for revising or removing standardized tests in education:
* Poor predictive quality.
* Grade inflation of test scores or grades.
* Culturally or socioeconomically biased.
* Psychologically damaging.
* Poor indicator of intelligence or ability.
Furthermore, student's success is being tracked to a teacher's relative performance, making teacher advancement contingent upon a teacher's success with a student's academic performance. Ethical and economical questions arise for teachers when faced with clearly underperforming or under-skilled students and a standardized test.
In her book, Now You See It, Cathy Davidson criticizes standardized tests. She describes youth as "assembly line kids on an assembly line model," meaning the use of the standardized test as a part of a one-size-fits-all educational model. She also criticizes the narrowness of skills being tested and labeling children without these skills as failures or as students with disabilities. Widespread and organized cheating has been a growing culture.
There are three metrics by which the best performing countries in the TIMMS (the "A+ countries") are measured: focus, coherence, and rigor. Focus is defined as the number of topics covered in each grade; the idea is that the fewer topics covered in each grade, the more focus can be given to each topic. The definition of coherence is adhering to a sequence of topics covered that follows the natural progression or logical structure of mathematics. The CCSSM was compared to both the current state standards and the A+ country standards. With the most topics covered on average, the current state standards had the lowest focus. The Common Core Standards aim to fix this discrepancy by helping educators focus on what students need to learn instead of becoming distracted by extraneous topics. They encourage educational materials to go from covering a vast array of topics in a shallow manner to a few topics in much more depth.

### Time and money

Standardized tests are a way to measure the education level of students and schools on a broad scale. From Kindergarten to 12th grade, most American students participate in annual standardized tests. The average student takes about 10 of these tests per year (e.g., one or two reading comprehension tests, one or two math tests, a writing test, a science test, etc.). The average amount of testing takes about 2.3% of total class time (equal to about four school days per year).
Standardized tests are expensive to administer. It has been reported that the United States spends about US$1.7 billion annually on these tests. In 2001, it was also reported that only three companies (Harcourt Educational Measurement, CTB McGraw-Hill and Riverside Publishing) design 96% of the tests taken at the state level.

### Educational decisions

The National Academy of Sciences recommends that major educational decisions not be based solely on a single test score. The use of minimum cut-scores for entrance or graduation does not imply a single standard, since test scores are nearly always combined with other minimal criteria such as number of credits, prerequisite courses, attendance, etc. Test scores are often perceived as the "sole criteria" simply because they are the most difficult, or the fulfillment of other criteria is automatically assumed. One exception to this rule is the GED, which has allowed many people to have their skills recognized even though they did not meet traditional criteria.
Some teachers would argue that a single standardized test only measures a student's current knowledge and it does not reflect the students progress from the beginning of the year. A result created by individuals that are not a part of the student's regular instruction, but by professionals that determine what students should know at different ages. In addition, teachers agree that the best test creator and facilitator are themselves. They argue that they are the most aware of students abilities, capacities, and necessities which would allow them to take a longer on subjects or proceed on with the regular curriculum.

### Effects on disadvantaged students

Monty Neill, the director of the National Center for Fair and Open Testing, claims that students who speak English as a second language, who have a disability, or who come from low-income families are disproportionately denied a diploma due to a test score, which is unfair and harmful. In the late 1970s when the graduation test began in the United States, for example, a lawsuit claimed that many Black students had not had a fair opportunity on the material they were tested on the graduation test because they had attended schools segregated by law. "The interaction of under-resourced schools and testing most powerfully hits students of color", as Neill argues, "They are disproportionately denied diplomas or grade promotion, and the schools they attend are the ones most likely to fare poorly on the tests and face sanctions such as restructuring."
In the journal The Progressive, Barbara Miner explicates the drawbacks of standardized testing by analyzing three different books. As the co-director of the Center for Education at Rice University and a professor of education, Linda M. McNeil in her book Contradictions of School Reform: Educational Costs of Standardized Testing writes "Educational standardization harms teaching and learning and, over the long term, re-stratifies education by race and class." McNeil believes that test-based education reform places higher standards for students of color. According to Miner, McNeil "shows how test-based reform centralizes power in the hands of the corporate and political elite—a particularly frightening development during this time of increasing corporate and conservative influence over education reform." Such test-based reform has dumbed down learning, especially for students of color.
FairTest says that negative consequences of test misuse include pushing students out of school, driving teachers out of the profession, and undermining student engagement and school climate.

## Use of standardized tests in university admissions

Standardized tests are reviewed by universities as part of the application, along with other supporting evidence such as personal statements, high school grades, previous coursework, and letters of recommendation. Different countries have different tests, such as the SAT in the US, the Gaokao in China, and the Joint Entrance Examination in India.
Nathan Kuncel, a scholar of higher education, says that college admission tests and other standardized tests "help overwhelmed admissions officers divide enormous numbers of applicants into pools for further assessment. High scores don't guarantee admission anywhere, and low scores don't rule it out, but schools take the tests seriously."
Research shows that the tests predict more than just first-year grades and the level of courses a student is likely to take. The longitudinal research conducted by scientists shows that students with high test scores are more likely to take the challenging route through college.
Tests also can indicate the outcomes of students beyond college, including faculty evaluations, research accomplishments, degree attainment, performance on comprehensive exams and professional licensure.
Since grading varies across schools, and even for two students in the same school, the common measure provided by the test score is more useful as a way to compare students.
However, in 1995, the Graduate Record Examinations (GRE) scores accounted for just 6 percent of the variation in grades in graduate school. The GRE appeared to be "virtually useless from a prediction standpoint," wrote the authors. Repeated studies of the Law School Admissions Test (LSAT) find the same.
There is debate whether the test will indicate the long-term success in work and life since there are many other factors, but fundamental skills such as reading, writing, and math are related to job performance. Major life accomplishments, such as publishing a novel or patenting technology, are also associated with test scores, even after taking into account educational opportunities. There is even a sizable body of evidence that these skills are related to effective leadership and creative achievements at work. Being able to read texts and make sense of them and having strong quantitative reasoning are crucial in the modern information economy. Students who scored in the top 1% at the age of 13. Twenty years later, they were, on average, very highly accomplished, with high incomes, major awards and career accomplishments.
Many arguments suggest that skills from tests are useful—but only up to a point.
There is a correlation between test scores and social class, but success on standardized tests and in college is not simply dependent on class. The studies show that "the tests were valid even when controlling for socioeconomic class. Regardless of their family background, students with good tests scores and high-school grades do better in college than students with lower scores and weaker transcripts."
Another criticism relating to social class and standardized testing is that only wealthy people receive test preparation and coaching. However, test prep programs often result in an increase of 5 to 20 points (out of 1600), which is far below the "100 to 200 points claimed by some test prep companies."
Many people believe that standardized tests reduce diversity in admissions, since disadvantaged members of racial minority groups have, on average, lower test scores than other groups. A 2012 comparison of universities where admissions tests are optional for applicants and schools that use the tests showed that "recent research demonstrates that testing-optional schools have been enrolling increasingly diverse student bodies. But the same is true of schools that require testing." In 2025, comparisons found that testing-optional admissions disproportionately harmed high-achieving students from lower-income backgrounds.
Opponents claim that standardized tests are misused and uncritical judgments of intelligence and performance, but supporters argue that these aren't negatives of standardized tests, but criticisms of poorly designed testing regimes. They argue that testing should and does focus educational resources on the most important aspects of education—imparting a pre-defined set of knowledge and skills—and that other aspects are either less important, or should be added to the testing scheme.
Evidence shows that black and Hispanic students score lower than whites and Asians on average. Therefore, the math and reading standard tests such as SAT have faced escalating attacks from progressives. However, a 2020 report found the tests are not discriminatory and play an important role in protecting educational quality. The report suggested that worsening grade inflation, especially at wealthy high schools, makes a standard assessment especially important.
Regarding UC schools' intention in dropping standard tests such as the SAT and ACT in college admissions, subjective and customized tests like essays and extra-curriculars can be easily tailored and detrimental to the students who are not familiar with the process. Admissions without testing may be even more tilted in favor of the well-connected.
In January 2020, the faculty senate at the University of California recommended that the UC system keep standardized tests as admissions requirements. The report says standardized math and reading tests are useful for predicting college performance. Based on data from the students in the UC system, the report concludes that "test scores are currently better predictors of first-year GPA than high school grade point average." The report continues: scores are also good at predicting total college GPA and the possibility a student will graduate. While the "predictive power of test scores has gone up," the report adds, "the predictive power of high school grades has gone down."
Test scores enable UC schools "to select those students from underrepresented groups who are more likely to earn higher grades and to graduate on time." "The original intent of the SAT was to identify students who came from outside relatively privileged circles who might have the potential to succeed in university," the report says. The SAT's maker, the Educational Testing Service (ETS), now claims the SAT is not an "aptitude" test but rather an assessment of "developed abilities".

## Testing issues not specific to standardization

Most tests can be classified on multiple categories. For example, a test can be both standardized and also a high-stakes test, or standardized and also a multiple-choice test. Complaints about "standardized tests" (all test takers take the same test, under reasonably similar conditions, scored the same way) are often focused on concerns unrelated to standardization and apply equally to non-standardized tests. For example, a critic may complain that "the standardized tests are all time-limited tests", but the focus of the criticism is on the time limit, and not on everyone taking the same test and having their answers graded the same way.

### High-stakes tests

Types of tests :
| | Low-stakes test | High-stakes test |
| Standardized test | A personality quiz on a website | An educational entrance examination to determine university admission |
| Non-standardized test | The teacher asks each student to share something they remember from their homework. | The theater holds an audition to determine who will get a starring role. |
A high-stakes test is a test with a desired reward for good performance. Some standardized tests, including many of the tests used for university admissions around the world, are high-stakes tests. Most standardized tests, such as ordinary classroom quizzes, are low-stakes tests.
Heavy reliance on high-stakes standardized tests for decision-making is often controversial. A common concern with high-stakes tests is that they measure performance during a single event, when critics believe that a more holistic assessment would be appropriate. Critics often propose emphasizing cumulative or even non-numerical measures, such as classroom grades or brief individual assessments (written in prose) from teachers. Supporters argue that test scores provide a clear-cut, objective standard that serves as a valuable check on grade inflation.

### Norm-referenced tests

A norm-referenced test is one that is designed and scored so that some test takers rank better or worse than others. The ranking provides information about the relative ranking, which is helpful when the goal is to determine who is best (e.g., in elite university admissions).

### Disagreement with educational standards

A criterion-referenced test is more common and more practical when the goal is to know whether the test takers have learned the required material.
However, some critics object to "standardized tests" not because they object to giving students the same test under the reasonably similar conditions and grading the responses the same way, because they object to the type of material that is typically tested by schools. Although standardized tests for non-academic attributes such as the Torrance Tests of Creative Thinking exist, schools rarely give standardized tests to measure "initiative, creativity, imagination...curiosity...good will, ethical reflection, or a host of other valuable dispositions and attributes". Instead, the tests given by schools tend to focus less on moral or character development, and more on individual identifiable academic skills, such as reading comprehension and arithmetic.
In his book, The Shame of the Nation, Jonathan Kozol argues that students submitted to standardized testing are victims of "cognitive decapitation". Kozol comes to this realization after speaking to many children in inner city schools who have no spatial recollection of time, time periods, and historical events. This is especially the case in schools where due to shortages in funding and strict accountability policies, schools have done away with subjects like the arts, history and geography; in order to focus on the content of the mandated tests.

### Test anxiety

Some people become anxious when taking a test. This phenomenon is more common for high-stakes tests than for low-stakes tests. High-stakes tests (whether standardized or non-standardized) can cause anxiety.
There is criticism from students themselves that tests, while standardized, are unfair to the individual student. Some students claim they 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 claim that they are at a disadvantage and 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 and forty percent of students experience this type of anxiety. Children living in poverty are struck most with testing anxiety. Testing anxiety applies to both standardized and non-standardized tests.

### Multiple-choice tests and test formats

A multiple-choice test provides the test taker with questions paired with a pre-determined list of possible answers. It is a type of closed-ended question. The test taker chooses the correct answer from the list.
Many critics of standardized testing object to the multiple-choice format, which is commonly used for inexpensive, large-scale testing and which is not suitable for some purposes, such as seeing whether the test taker can write a paragraph. However, standardized testing can use any test format, including open-ended questions, so long as all test takers take the same test, under reasonably similar conditions, and get evaluated the same way.

### Teaching to the test

Teaching to the test is a process of deliberately narrowing instruction to focus only on the material that will be measured on the test. For example, if the teacher knows that an upcoming history test will not include any questions about the history of music or art, then the teacher could "teach to the test" by skipping the material in the textbook about music and art. Critics also charge that standardized tests encourage "teaching to the test" at the expense of creativity and in-depth coverage of subjects not on the test. Critics say that teaching to the test disfavors higher-order learning; it transforms what the teachers are allowed to be teaching and heavily limits the amount of other information students learn throughout the years. While it is possible to use a standardized test without letting its contents determine curriculum and instruction, frequently, what is not tested is not taught, and how the subject is tested often becomes a model for how to teach the subject.
Externally imposed tests, such as tests created by a department of education for students in their area, encourage teachers to narrow the curricular format and teach to the test.
Performance-based pay is the idea that teachers should be paid more if the students perform well on the tests, and less if they perform poorly. 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. New Jersey Governor Chris Christie proposed educational reform in New Jersey that pressures teachers not only to "teach to the test," but also have their students perform at the potential cost of their salary and job security. The reform called for performance-based pay that depends on students' performances on standardized tests and their educational gains.
Critics contend that overuse and misuse of these tests harms teaching and learning by narrowing the curriculum. According to the group FairTest, when standardized tests are the primary factor in accountability, schools use the tests to narrowly define curriculum and focus instruction. Accountability creates an immense pressure to perform and this can lead to the misuse and misinterpretation of standardized tests.
