Australia

In Australia, children undergo thirteen years of formal education (plus non-compulsory preschool or kindergarten), usually starting at age 4, 5 or 6, and finishing at age 17, 18 or 19. The years are numbered from "Kindergarten" to 12.

In New South Wales (NSW), Western Australia (WA), South Australia (SA), Victoria (VIC) and Queensland (QLD) and Tasmania (TAS) primary school is Kindergarten (NSW)/Pre-primary (WA)/Reception (SA)/Prep (VIC, QLD & TAS) and Years 1–6, and secondary school, Years 7–12 (see table below).

In the Australian Capital Territory (ACT), primary school is Kindergarten/years 1–6, high school is years 7–10, and college or Senior Secondary is years 11 & 12 & 13 (see table below).

In the Northern Territory (NT),^[3] primary school is Transition/years 1–6, middle school is years 7–9, and high school or Senior Secondary is years 10–12 (see table below).

Azerbaijan

Belarus

In Belarus, education is guaranteed for everyone. Primary school lasts for 4 years, but some psycho-physically challenged children study for 5 years according to a special standard. Forms 1 to 9 are considered compulsory. After completing general basic school a person can study in a special establishment to get a job. To enter a higher educational establishment a person must complete general secondary school (all 11 forms) and pass three centralized tests.^[4]

Brazil

In Brazil, there are three levels of basic education: "Educação Infantil" (preschool), "Ensino Fundamental" (primary school) and "Ensino Médio" (high school), which are generally completed by age eighteen. Basic education is designed to provide the necessary minimum knowledge for the exercise of citizenship. It also serves to develop consciousness for choosing future professions. In Brazil, after the name of the grade one may use the names "série" (series) or "ano" (year). The educational stages in Brazil are divided as follows:

Canada

In Canada, schooling officially begins at Kindergarten (or Maternelle in Quebec), followed by grades, with some variations for certain levels in certain provinces/territories. When referred to as a grade, school years are usually referred to by their cardinal number ("Grade Three").

At the post-secondary level in (Anglophone) Canada, a student is usually referred to by the year of study they are in (i.e. First Year, Second Year, etc.). If they are pursuing something higher than an undergraduate degree, the designation usually refers to what year of study they are in since entering Graduate studies (i.e. First Year Graduate Student, etc.). Any student who has completed their first year of undergraduate studies is considered to be an Upper Year Student.

Each province and territory has its own autonomous education system. As such, the name of each level of education and what year each level begins at will vary across the country (as will the curriculum itself).

China

In the People's Republic of China (excluding Hong Kong and Macau), the years are organized in three stages and renumbered within each stage: 6 years in elementary school (小学) years 1 to 6, then 3 years in middle school (初级中学, abbreviated 初中) years 7 to 9, then 3 years in high school (高级中学, abbreviated 高中) years 10 to 12. The first nine years (elementary 1–6 and middle 1–3) are compulsory, and the years in high school are voluntary. Completing higher secondary education or attaining an equivalent level is required before one may receive higher education (高等教育) at universities.

France

Education is compulsory from age 3 to age 16, and then compulsory training until the age of 18. This law was passed during the Macron presidency and approved the law. At the end of the lycée cursus, is the French Baccalaureat exam. It is possible in France to fail a year, and need to repeat (redoubler).

Greece

Education is compulsory from age 4 to age 15. Education is provided in public and private schools, except Higher Education which is provided only by public universities.

Hong Kong

The Hong Kong system was based on the United Kingdom system, with zero to three optional years at kindergarten, six years of primary school (小學) and six years of secondary school (中學), followed by four years at university. Primary 1–6 (小一 – 小六) corresponds to Years 1–6 in the UK, and Forms 1 – 6 (中一 – 中六) correspond to Years 7–12. Usually students begin Primary 1 at age 5 or 6 and complete Form 6 at age 17 or 18.

In Hong Kong, international schools follow the system of the country they are based upon, for example the English Schools Foundation uses the UK year system, and the French International School of Hong Kong uses the French école, collège, lycée system. Also, the English term form followed by the English number is common usage even in otherwise Cantonese conversations.

Iceland

India

The central and most state boards uniformly follow the "10+2+3" pattern of education. In this pattern, study of 10 years is done in schools and 2 years in Junior colleges, and then 3 years of graduation for a bachelor's degree. The first 10 years is further subdivided into 4 years of primary education, 6 years of High School followed by 2 years of Junior colleges. This pattern originated from the recommendation of the Education Commission of 1964–66.

Indonesia

In Indonesia, children spend 12 years of formal education, but some children attend nursery playgroup (called Kelompok Belajar in 2 years) and attend kindergarten (Called Taman Kanak-Kanak in 2 years).

Iran

The Iranian system has experienced several changes in the last seven to eight decades. Prior to 1940–1950, the education system had consisted of three levels, called in order: an optional year in kindergarten, six years of primary school, finally followed by six years of secondary school ending up with a diploma. After some improvements during Mohammad Reza Shah Pahlavi, the system was changed to four consecutive periods: two optional years in kindergarten and pre-primary school, primary school consisting of 5 years, 3 years in middle school, and finally four years in high school. The system ended up by honoring a diploma in certain majors, e.g. math and physics.

Around 1996–1997, one year was reduced from the entire education system and one was honored with a diploma after three years in high school. However, if one would have liked to continue her/his education towards university degrees, one would have been required to take the last year, so called pre-university year. This year had been a requirement to participate in the Iranian University Entrance Exam for high school students. Again, around 2012, the system turned back to its previous system, consisting of two 6-year periods.

There are two formal stages of education in Iran: primary school (دبستان, Dabestãn) and high school (دبیرستان, Dabirestãn). The high school itself is broken into 2 parts: A and B.^{[further explanation needed]} Preschool educations are informal, therefore Grade 1 is the first year. In Grade 1 (پایه‌ی 1, Paye 1) also known as the 1st class (کلاس اوّل, Klãs Avval), children learn the basics of reading and writing.

Ireland

In the Republic of Ireland, there are two levels of compulsory education; primary school (ca.4–12 years of age) and secondary school (ca.12–18 years). The names of each class are as follows:

• Junior Infants (4–5 years)
• Senior Infants (5–6 years)
• First Class (6–7 years)
• Second Class (7–8 years)
• Third Class (8–9 years)
• Fourth Class (9–10 years)
• Fifth Class (10–11 years)
• Sixth Class (11–12 years)

After Sixth Class, students move to secondary school, entering;

• First Year (12–13 years)
• Second Year (13–14 years)
• Third Year (14–15 years) – Junior Certificate
• Fourth Year [or Transition Year] (15–16 years)
• Fifth Year (15–17 years)
• Sixth Year [or Final Year] (16–18 years) – Leaving Certificate

In some schools, Transition Year is compulsory, in others it is optional.

Japan

In Japan, the years are organized in three stages and renumbered within each stage: 6 years in elementary school (小学校, shōgakkō) years 1 to 6, then 3 years in lower secondary (中学校, chūgakkō) years 1 to 3, then 3 years in higher secondary (高等学校, kōtōgakkō, abbreviated 高校, kōkō) years 1 to 3. The first nine years (elementary 1–6 and lower secondary 1–3) are compulsory, and the years in higher secondary school are voluntary. Completing higher secondary education or attaining an equivalent level is required before one may receive higher education at universities (大学, daigaku).

Malaysia

Compulsory education in Malaysia spans a period of 11 years and comprises both primary and secondary education. Kindergarten is optional.

Malaysian primary school consists of six years of education, referred to as Year 1 to Year 6 (formerly Standard 1 to Standard 6). Year 1–3 are classified as Level One (Tahap Satu in Malay) while Year 4–6 make up Level Two (Tahap Dua). Primary schooling usually begins at the age of 7 and ends at 12. Students take their first national examination, the UPSR, towards the end of the Year 6 school year. Performance in the UPSR has no effect on their resuming schooling; all students continue with their secondary education after leaving primary school.

Secondary schooling usually begins at age 13. Secondary schools offer education for a total of five years, starting with Form 1 and finishing at Form 5. Forms 1–3 are grouped together into the "Lower Form" and Forms 4 and 5 are considered the "Upper Form". Students in Form 3 will have to sit for their second national exam, the PT3. They are then streamed into sciences or humanities classes for the Upper Form according to their performance in this exam. At age 17 students in Form 5 sit for the final level of national examinations, the SPM (Malaysian Certificate of Education). Achieving a passing grade in the Bahasa Melayu (Malay Language) portion of the exams is compulsory; failure results in an automatic failing grade for all subjects taken in the examination and the student is held back to repeat Form 5. Completion of the examination signifies that the student has completed formal education in Malaysia; an SPM certificate remains the base requirement to secure most jobs in Malaysia.

After the SPM, students have a choice of either continuing with Form 6 (which comprises 2 years, Lower and Upper Six) or entering matriculation (pre-university programs). If they opt for Form 6, they will be required to take the STPM examination. Although generally taken by those desiring to attend public universities in Malaysia, an STPM certification is internationally recognized and may also be used, though rarely required, to enter private local universities for undergraduate courses.

Mexico

In Mexico, grades 1 through 12 can be divided into two stages: Educación Básica, and Educación Media Superior.^[16] Educación Básica covers pre-primary education to the equivalent of ninth grade.^[17] Educación Media Superior covers tenth through twelfth grade, and students' levels are identified by their current semester, not by their grade.^[18]

Nepal

In Nepal, the stages of education are primary education, secondary education, and higher secondary. Pre-primary education is also found in some areas. Generally, the pre-primary level covers nursery and kindergarten. Primary education consists of grades one through five, while lower secondary education covers grades six through eight and secondary education covers grades nine through ten. Higher secondary covers grades eleven and twelve. Students get Secondary Education Examination certificate in grade ten. According to the new Education Act, the national grade 12 Examination will result in the School Leaving Certificate (SLC).

New Zealand

In New Zealand children are required by law to attend 10 years of educational instruction, from the age of 6 to 16. The law also provides in the same legislation that all people are allowed to attend free education to the age of 18, this legislation is the Education Act 1989. Children can be enrolled at primary school when they turn five years old, and must be enrolled by the time they turn six years old. From years 1–6 students attend primary school. In years 7 and 8 students attend intermediate, or a joint school (years 1–8 or years 7–13). The final years of free education are spent in secondary school (years 9–13). New Zealand also has two older educational stage-numbering systems; standards 5 and 6 were largely unused with the introduction of intermediate schools in the 1950s, while "primmer" numbering was in use well into the 1970s, and some academically focused secondary schools still use "form" numbering.

Norway

In Norway children start school at the age of six; before that kindergarten is voluntary. This school is called barneskole (childrenschool):

• 6–7: First grade
• 7–8: Second grade
• 8–9: Third grade
• 9–10: Fourth grade
• 10–11: Fifth grade
• 11–12: Sixth grade
• 12–13: Seventh grade

The second school is ungdomsskole (youth-school). At this level the students are rated with grades in each subject, in addition to behavior and orderliness:

• 13–14: Eighth grade
• 14–15: Ninth grade
• 15–16: Tenth grade

The last school before higher education is called videregående skole (ongoing school) and is voluntary, though most choose to attend. At this level students decide among separate career-related schools. The most popular such school is designed to prepare one for further education,^{[citation needed]} while others prepare students for such as mechanics, electricians, cooks and so on. Educational stages in these schools begin again at "one" and are named Vg1, Vg2, Vg3 and Vg4. Some of the more practical schools last only two years, and some students may choose to attend an extra year to study higher education. The typical duration is three years, though some schools offer a four-year program to enable students to engage in more athletics or gather real work experience.

• 16–17: Vg1
• 17–18: Vg2
• 18–19: Vg3
• 19–20: Vg4

Philippines

From 1945 until 2017, there were ten years of compulsory education under the K–10 system until it phased out entirely on June 5, 2017. Grades 11 and 12 were added on June 13, 2016, as a result of the K–12 implementation four years earlier on June 4, 2012. School years start in the first or second week of June, and end in the last week of March or first week of April. There are three stages of education in the Philippines – elementary school, junior high school, and senior high school.

Poland

From 1998 to 2019, the Polish education system was divided into six years of primary education, followed by three years of secondary education and three or four years of optional high school education. Attending general education high school or vocational school allows graduates to attend university while attending a basic vocational school (zasadnicza szkoła zawodowa) requires its graduates to attend supplementary liceums if they wish to proceed with university education. Since 2019, the three stages were merged into two, returning to the country's pre-reform system. Kindergarten education is optional, while compulsory education starts with year 0. The school year lasts from early September to late June, with the exception of the final year of high school, which ends in late April, followed by matura exams throughout May.
The "Age" column represents the age at which children start a school year.

Russia

In Russia, compulsory education lasts eight or nine years and begins the year the child turns seven (8 years) or, sometimes, six (9 years). The first stage of elementary school can last either 3 years (so called 1–3 programme for children starting at the age of 7) or 4 years (so called 1–4 programme for children starting at the age of 6). After of the first stage all pupils enter 5th grade, thus pupils that started at the age of 7 do not attend the 4th grade.

While it is not compulsory to remain in school after graduating from middle school, a student cannot progress to tertiary school without graduating from high school or vocational school.

Serbia

In Serbia, children undergo thirteen years of formal education, usually starting at age 4, 5 or 6, and finishing at age 18 or 19. By the law children need to enter Primary school at the year they will turn 7 years of age, with some wiggle room if the child is born too close to a new year. The first four years of primary school, children have their own classroom and one teacher that teaches them all the subjects, from grade 5 of primary school to the end of high school lessons are held by number of teachers specialised for specific subjects and children change their classrooms every class. Children start their school year on September 1, and end the year at the end of June/beginning of July. The exception is the grade 8 of primary school and the grade 4 of high school when the classes end a couple of months earlier so the children can study for their entry exams for high school/college. Depending on which high school a child chooses, they can get more focused education and a professional degree. High school is not compulsory education but is needed to get some professional degrees in order to be able to find a job (for example: Nurse, Locksmith, Computer network administrator, Textile design technician, etc.)

Singapore

In Singapore, compulsory education lasts ten years and begins the year the child turns seven. However, most children receive a preschool education spanning two to three years before entering primary school after which they will move on to a secondary school, where Sec 5 is only made compulsory for students who have achieved a determined score for their PSLE. For Secondary School, there are three streamings: Express (Exp), Normal Academic (NA), and Normal Technical (NT), among which Exp and NT students study for four years while NA students need to study for five years. The Exp stream leads to a Singapore-Cambridge GCE Ordinary Level while the NA and NT stream leads to a Singapore-Cambridge GCE Normal Level. Some schools also offer the Integrated Programme which combines secondary school and junior college to directly offer the Singapore-Cambridge GCE Advanced Level. Depending on which stream one is in, and whether the school's scoring requirement is met, a student may be retained/transferred to NA/NT.

While it is not compulsory to remain in school after graduating from secondary school, most go on to receive their tertiary education at a Junior College, a polytechnic, or an institute of technical education (ITE) before moving on to university. Most junior colleges offer the Singapore-Cambridge GCE Advanced Level while some offer the International Baccalaureate after 2 years of study.

Spain

In Spain, education is divided into several stages: Kindergarten, primary education and secondary education. Kindergartens are schools for children 0–3 years old, and are normally private institutions, although some of them receive public funding as well ("Concertados"). Primary education is delivered almost exclusively through primary schools which offer education for pupils aged between 3 and 12. Children are entitled to preschool education from their third birthday, although it is not compulsory (but it is recommended) and must enter compulsory education from the September after their 5th birthday. There is some leeway in the starting date for pupils.

Education lasts 6 years in the compulsory section of primary school, before pupils move to a secondary school for between 4 and 6 years, the last two being optional. There is some variation in the phasing of education because private institutions may provide education from kindergarten or primary school until the end of secondary school, and private institutions with public funding normally teach from kindergarten until the 4th year in the secondary school level.

Sri Lanka

Sri Lanka enforces compulsory education and it is mandatory for a child to at least complete one year of pre-school by the time the child reaches the completion of age 4. By the time they have reached the age of 5 years, enrollment to Grade 1 is made a legal obligation with continuation through at least age 14.

Primary school to higher education are primarily funded and overseen by two governmental ministries and the main Department.^[19]

• Ministry of Education
  • Department of Examinations
• Ministry of Higher Education

Sweden

In Sweden children start school at the age of six with preschool class; before that preschool is voluntary.

• 6–7: Preschool class (Förskoleklass)

First set of grades are called "lågstadiet" (low grades).

• 7–8: "ettan" (First Grade)
• 8–9: "tvåan" (Second Grade)
• 9–10: "trean" (Third grade)

Second set of grades are called "mellanstadiet" (middle grades).

• 10–11: "fyran" (Fourth grade)
• 11–12: "femman" (Fifth grade)
• 12–13: "sexan" (Sixth grade)

Third set of grades are called "högstadiet" (high grades).

• 13–14: "sjuan" (Seventh grade)
• 14–15: "åttan" (Eighth grade)
• 15–16: "nian" (Ninth grade)

The last school before higher education is called "gymnasiet" (ongoing school) and is voluntary, though most choose to attend. At this level students decide among separate career-related programmes.

• 16–17: "första ring" (First Level)
• 17–18: "andra ring" (Second Level)
• 18–19: "tredje ring" (Third Level)

United Kingdom

United States

In the United States (U.S.), grades traditionally begin at 1 and run to 12; they are referred to by ordinal number (e.g., first grade or 1st grade). An additional preceding level called kindergarten ("K") is now standard in most areas, and a further preceding level called preschool education or nursery school is not uncommon. In some parts of the state of Wisconsin, kindergarten is split further into junior and senior kindergarten.

Before the term "middle school" became much more common, 7th and 8th grades were placed in "junior high school". In certain junior high schools, either 6th grade or 9th grade was also included (but not both in the same school).

At the secondary school level ("high school"), the 9th through 12th grades are also known respectively as freshman (or "first-year"), sophomore, junior, and senior. At the postsecondary or "undergraduate" level (college or university), the same four terms are reused to describe a student's college years, but numbered grades are not used at the college level. American graduate and postgraduate education does not use grades.

The adjacent Table US outlines the ages, in years, of each grade level in the US. However, students are sometimes older because of grade retention or younger because of grade skipping.

Elementary school students at a specific grade level are traditionally assigned to a single class that usually stays together in the same classroom with the same teacher throughout each school day for the entire school year (although the teacher may temporarily hand off the class to specialists for certain subject matter units, especially science). Students in middle school and high school are allowed to build schedules from a mix of required and elective courses taught by different teachers in different classrooms, must rush from one course to the next during each school day, and are more likely to encounter students from different grades in their courses (especially electives).
