# College Scholastic Ability Test

The College Scholastic Ability Test or CSAT (Korean: 대학수학능력시험; Hanja: 大學修學能力試驗), also abbreviated as Suneung (수능; 修能), is a standardised test which is recognised by South Korean universities. The Korea Institute of Curriculum and Evaluation (KICE) administers the annual test on the third Thursday in November.
The CSAT was originally designed to assess the scholastic ability required for college. Because the CSAT is the primary factor considered during the Regular Admission round, it plays an important role in South Korean education. Of the students taking the test, as of 2023, 65 percent are currently in high school and 31 percent are high-school graduates who did not achieve their desired score the previous year. The share of graduates taking the test has been steadily rising from 20 percent in 2011. Despite the emphasis on the CSAT, it is not a requirement for a high school diploma.
Day-to-day operations are halted or delayed on test day. Many shops, flights, military training, construction projects, banks, and other activities and establishments are closed or canceled. The KRX stock market opens late.

## Purpose

The CSAT is designed to test a candidate's ability to study in college, with questions based on Korea's high-school curriculum. It standardises high-school education and provides accurate, objective data for university admission.

## Schedule

All questions are multiple-choice, except for the 9 questions in the Mathematics section, which are short answer.

## Sections

The CSAT consists of six sections: Korean, Mathematics, English, Korean history, one chosen subject from Social science, Natural science, and Vocational education, and a Second language and Classical Chinese. All sections are optional except Korean history, but most candidates take all the other sections except a second foreign language and Classical Chinese.
In the Mathematics section, candidates take Math I (which consists of logarithms, sequences and trigonometry) and Math II (which consists of limits, precalculus and calculus), and are allowed to select one topic among probability and statistics, geometry and calculus.
The subordinate subjects are divided into three sections: social studies, science, and vocational education. Candidates may choose up to two subjects, either from the 17 science or social studies subjects, or from the vocational education subjects. For example, Physics II and Biology I may be chosen for the subordinate section since both are sciences, Chemistry I and Society and Culture may be chosen as well, but World history and Principles of Accounting may not – the former is in the social studies section, and the latter in vocational education. Only vocational high-school graduates can choose the vocational education section, accounting for only 1% of test-takers. The split between sciences and social studies has been fairly even, but in 2024, the number of students taking social studies subjects (225135) overtook the number taking sciences (174649), while the percentage of students taking one science and one social studies exceeded 10%.
In the second language/Classical Chinese section, the candidate chooses one subject.
Most high-ranked universities require applicants to take two science subordinate subjects and Geometry or Calculus in the mathematics section if they apply for a STEM major, and do not accept subordinate subjects in the same field (such as Physics I and Physics II). However, in 2024, most universities abolished the two sciences rule, leading to an influx of students from science to social studies. The only universities that required two science subjects for non-medical STEM majors were Seoul National University, Korea University, and Hongik University, while most medicine-related maintained the restriction. Korea University and Hongik University have announced plans to abolish the rule in the 2025 exam for the 2026 school year.
In 2023, the Ministry of Education announced revisions that will take effect starting in 2027, which includes abolishing electives, including Korean Language and Mathematics electives, and replacing different Natural science and social studies subjects with Integrated Science and Integrated Social Studies.

### Korean Language

In the Korean Language section, candidates are assessed on their ability to read, understand and analyse Korean texts rapidly and accurately. Its 45 questions of the subject are classified into four categories:
Common topics
* Questions 1-17: Reading
* Questions 18-34: Literature
Elective topics (select 1 out of 2 options, Q35-45)
* Speech and Writing
* Language and Media

#### Common subjects
##### Reading

This category consists of four articles. Each passage has 3-6 questions from the topics of reading theory, humanities/arts, law/economy and science/technology respectively.
| Passage Topic | Contents |
| Reading theory | Article about the significance of reading or a reading journal written by a student |
| Humanities | A passage about a thinker and their theories from the topics historiography or philosophy (Western and Eastern ethics, logic). The questions normally feature a single person presenting their opinions or two thinkers with opposing opinions. |
| Arts | Focus on an artist and their works in the fields of music, visual arts and architecture. |
| Society (Law/economy) | Common law topics are: Civil Code, Administrative law, Philosophy of law, Penal code, commercial act and the Korean Constitution Common economy topics are: macroeconomics and international economics |
| Science | Biology (especially physiology and biochemistry), astronomy, physics, earth science, chemistry and mathematics |
| Technology | Texts generally focus on how specialised machines and systems work. Recently texts have focused on newer technologies such as 3D modelling and the metaverse. |
| Mixed | Some texts feature a combination of two topics. For example, in 2017 September mock exam, a question featuring both the arts and technology was about the scientific origin and the artistic use of concrete architecture. In the 2019 exam, science and the humanities was mixed in a text about the differing viewpoints of Eastern and Western philosophers regarding the universe. |

##### Literature

This category consists of texts from five categories: classical poetries such as Hyangga, Sijo, Gasa and Goryeo Gayo, classical novels and prose, contemporary poetry, contemporary novels and play and essays. Candidates may be asked to summarise a single passage or outline a common theme between multiple texts (sometimes of different text types), among many other question types.

#### Elective subjects
##### Speech and writing

This category consists of 11 questions relating to three texts.
| Question | Text | Text types | Common questions asked |

The history of the Korean language concerns ancient and medieval Korean. Phonology, syntax and morphology involves the patternised principle and exceptional principle. Dialect of Korean and Jeju Language are usually deal with Korean dialects in Korea and historical features in specific dialects of Korean.
An additional topic may be used to complete the required five, or two questions are taken from morphology or syntax. Media forms questions 40-45 and relates to the characteristics of media and the creation of an online post or message.

### Mathematics

All mathematics candidates take the Maths I and II and select one elective topic from three choices: Calculus, Geometry or Probability and Statistics. Calculus is most preferred by students applying for natural science majors, while Probability and Statistics are preferred by students applying for the humanities. Geometry is the least popular, with only 4.1% of students selecting it as their elective.

## Writing of the test

The problems are created by selected members who are university professors and high-school teachers and chosen by KICE. Two groups make the problems: one creates them, and the other reviews and revises them.
The creators are primarily professors and high-school teachers review the questions. Both groups sign non-disclosure agreements with the KICE. In 2012, there was a total of 696 staff members involved in creating the problems. A member of the group earns about $300 per day.
In addition to professors, professional practitioners and high school teachers, Educational Civil Officers from the Ministry of Education of Korea, Education Ministries of the provinces of Korea and the Korea Institute of Curriculum and Evaluation are also present to review the exams. Onsite are protected by security personnel from the Korean National Police and National Intelligence Service, along with support staff including cooks, medical doctors, pharmacists and nurses.
Hotels and resorts owned by private companies and training centres owned by the Government of Korea in remote places are used for test writers. It is closed to visitors.

## Administration

High-school graduates and final-year high school students are allowed to sit the test. After the KICE prints test papers and OMR cards, they are distributed three days before the test to each test area. In 2018, there were 85 test areas.
On test day, the KRX stock markets in Busan and Seoul open late, and Public Transport such as Metro System, Light Metro, Light rail, Metropolitan Railways and bus services are increased to avoid traffic jams and allow students to get to the testing sites more easily. The Korean Armed Forces, USFK and UNC change the schedule of military activities to minimise the noises. Planes are grounded during the listening portion of the English section so their noise does not disturb the students.
In some cases, students running late for the test may be escorted to their testing site by police officers via motorcycle. Younger students and members of the students' families gather outside testing sites to cheer them on. Neither students nor administrators may bring in mobile phones, books, newspapers, food, or any other material which could distract other test-takers.
Middle and high school teachers monitor the test. Most testing rooms are high-school classrooms, and there is a 28-candidate limit in each room. Administrators are warned against doing anything which could distract students in any way such as talking, opening windows, standing in front of a desk, sniffling, or making excessive noise. After the test, the marking of the texts takes about one month.
Except for the English and Korean-history sections, grades are based on a stanine curve. A grade, percentile, and a standardised score for each section and subject are added to the transcript. The standardised score is calculated by the following formula:
S=zσ+m{\textstyle S=z\sigma +m}
$S$ and $z$ are standard scores. $\sigma$ is the standard deviation of the standard score, and $m$ is its average. In the national-language and mathematics sections, $\sigma$ is 20 and $m$ is 100. For the rest, $\sigma$ is 10 and $m$ is 50. $z$ is calculated by the following formula:
$z={\frac {x-m_{0}}{\sigma _{0}}}$
$x$ is the candidate's original score. $m_{0}$ is the average of the original $a$ candidate scores. $\sigma _{0}$ is the candidate's standard deviation.

## Preliminary College Scholastic Ability Test

The Preliminary College Scholastic Ability Test (PCSAT) is administered nationally. The relationship between PCSAT and CSAT is comparable to that between the PSAT and the SAT in the United States. The PCSAT is divided into two categories: the National United Achievement Tests (NUAT) and the College Scholastic Ability Test Simulation (CSAT Simulation). These tests are more similar to the CSAT than privately administered mock tests, since the PCSAT's examiner committee is similar to that of the CSAT. The CSAT Simulation is hosted by the same institution as the CSAT, and is used to predict the level of difficulty or types of questions which might appear on that year's CSAT.
Although the NUAT and the CSAT Simulation are similar to the CSAT in their number of candidates, types of questions and relative difficulty, the NUAT is hosted by the Ministry of Education for high-school students. The CSAT Simulation is run by KICE and may be taken by anyone who is eligible for the CSAT. Both exams are reliable, official mock tests for the CSAT, and both are graded by the KICE.

### National United Achievement Test

The National United Achievement Test (NUAT, Korean: 전국연합학력평가; Hanja: 全國聯合學力評價) is administered in the same way as the CSAT, and was introduced in 2002 to relieve dependence on private mock tests. High-school students may apply to take the test, and local education offices decide whether it will be administered in their districts. Every office of education in South Korea normally participates in the NUAT to prepare students for the CSAT, and the number of applicants parallels the CSAT. The Seoul Metropolitan Office of Education, Busan Metropolitan Office of Education (freshmen and sophomores), Gyeonggi-do Office of Education, and Incheon Office of Education take turns creating the questions, and the KICE grades the test and issues report cards.
The basic structure of the exam is identical to the CSAT. For mathematics, social studies, science and second language, its range is determined by when it is conducted. In the Korean and English sections, the questions are not directly from textbooks but are constructed in accordance with the curriculum.
As of 2014, there are four NUATs per year; it is not the same for every district, however, and some have only two exams per year for freshmen and sophomores. The NUAT for freshmen and sophomores is held in March, June, September and November; seniors are tested in March, April, July and October to avoid conflict with June and September, when the CSAT Simulation is given.

#### Administering institutions

* November: Gyeonggi-do Office of Education (freshmen and sophomores, except 2003)
* December: Seoul Metropolitan Office of Education (freshmen 2003)

### College Scholastic Ability Test Simulation

The College Scholastic Ability Test Simulation (CSAT Simulation, Korean: 대학수학능력시험 모의평가) is given by KICE. Unlike the NUAT, anyone who is eligible for the CSAT may also take this test. The CSAT Simulation was introduced after the CSAT failed to set the proper difficulty level in 2001 and 2002. First implemented in 2002, it was held only in September during its early years. The test has been given twice a year, in June and September, since 2004. It covers everything in the curriculum for the Korean- and second-language sections, and two-thirds of what the CSAT covers for the other sections. The September exam covers everything in every section, like the CSAT. The number of questions and test time per section is identical to the CSAT.

## History

Since the liberation of Korea, South Korea has changed its methods of university and college admission from twelve to sixteen times. The policies ranged from allowing colleges to choose students to outlawing hagwons. Parents and students have had difficulty adjusting to the changes. The changes have been cited as evidence of systemic instability and the sensitivity of the admission process to public opinion.
University and college admissions were first left to the universities, and the first CSAT incarnation appeared at the beginning of 1960. The Supreme Council for National Reconstruction established an early CSAT from 1962 to 1963 as a qualification test for students. Due to the small number of students passing the test, colleges soon had a student shortage. The admissions process was criticized as inefficient, and the government scrapped the policy from 1964 to 1968. A similar policy was adopted in 1969 by the Third Republic of Korea, and the new test was the Preliminary College Entrance Examination (대학입학예비고사); it continued, mostly unchanged, until 1981. That year, the policy was significantly changed. The test name was changed to Preliminary College Preparations Examination (대학예비고사), and hagwons (cram schools) were outlawed. In 1982, the test name was changed again to College Entrance Strength Test (대입학력고사).
In the 1990s, there was a rumour that if students had the S-shaped emblem, they could go to a prestigious university (Seoul National University), and if they had the letter III, they could get a score of 300 on the CSAT, which led to the Onata incident in which test takers secretly removed the Sonata III emblem. There were many Sonata IIIs with the letters S and III missing from the emblem and for this reason, Hyundai Motors implemented a free emblem replacement service.
The current CSAT system was established in 1993, and has undergone several revisions since then. In 2004, the government of South Korea introduced a 2008 College Admissions Change Proposal; however, it failed to bring about significant changes. In 2020, the exam was postponed to the first Thursday in December (December 3) due to the COVID-19 pandemic.
The Korean Education Ministry is planning to remove "killer questions" from the Suneung in 2024 after a failed attempt to do so in 2023, citing an excessive reliance on private education and academic pressure.

## Reception

Pressure to perform well on the CSAT has been linked to psychological stress, depression and suicide. The highly competitive exam has also cited as a contributing factor to South Korea's declining birth rate, as parents often pay for expensive hagwon cram schools to help their children study. Critics say this prevalence of cram schools gives students from wealthier families an advantage, and that the test detracts from students' education with its emphasis on rote memorization and topics that are distinct from the curriculum followed in schools. In 2023, the average amount per month spent on private education per student rose to a record high of ₩434,000 (US$300), with 78.5% of students participating in private education. The average student spent 7.3 hours each week in private education.
Considered one of the most important days of a South Korean's life due to its role in determining which university a student gains admission to, the excessive reliance on the Suneung as a means of determining a student's future has also been criticised. Despite this, the test has been noted for its efficiency, emphasis on merit and educational outcomes.
