A school is an educational institution designed to provide learning spaces and learning environments for the teaching of students (or "pupils") under the direction of teachers. Most countries have systems of formal education, which is commonly compulsory. In these systems, students progress through a series of schools. The names for these schools vary by country (discussed in the Regional section below) but generally include primary school for young children and secondary school for teenagers who have completed primary education. An institution where higher education is taught, is commonly called a university college or university, but these higher education institutions are usually not compulsory.
In addition to these core schools, students in a given country may also attend schools before and after primary (Elementary in the US) and secondary (Middle school in the US) education. Kindergarten or preschool provide some schooling to very young children (typically ages 3-5). University, vocational school, college or seminary may be available after secondary school. A school may be dedicated to one particular field, such as a school of economics or a school of dance. Alternative schools may provide nontraditional curriculum and methods.
There are also non-government schools, called private schools. Private schools  may be required when the government does not supply adequate, or special education. Other private schools can also be religious, such as Christian schools, madrasa, hawzas (Shi'a schools), yeshivas (Jewish schools), and others; or schools that have a higher standard of education or seek to foster other personal achievements. Schools for adults include institutions of corporate training, military education and training and business schools.
In home schooling and online schools, teaching and learning take place outside a traditional school building. Schools are commonly organized in several different organizational models, including departmental, small learning communities, academies, integrated, and schools-within-a-school.
The concept of grouping students together in a centralized location for learning has existed since Classical antiquity. Formal schools have existed at least since ancient Greece (see Academy), ancient Rome (see Education in Ancient Rome) ancient India (see Gurukul), and ancient China (see History of education in China). The Byzantine Empire had an established schooling system beginning at the primary level. According to Traditions and Encounters, the founding of the primary education system began in 425 AD and "... military personnel usually had at least a primary education ...". The sometimes efficient and often large government of the Empire meant that educated citizens were a must. Although Byzantium lost much of the grandeur of Roman culture and extravagance in the process of surviving, the Empire emphasized efficiency in its war manuals. The Byzantine education system continued until the empire's collapse in 1453 AD.
In Western Europe a considerable number of cathedral schools were founded during the Early Middle Ages in order to teach future clergy and administrators, with the oldest still existing, and continuously operated, cathedral schools being The King's School, Canterbury (established 597 CE), King's School, Rochester (established 604 CE), St Peter's School, York (established 627 CE) and Thetford Grammar School (established 631 CE). Beginning in the 5th century CE monastic schools were also established throughout Western Europe, teaching both religious and secular subjects.
Islam was another culture that developed a school system in the modern sense of the word. Emphasis was put on knowledge, which required a systematic way of teaching and spreading knowledge, and purpose-built structures. At first, mosques combined both religious performance and learning activities, but by the 9th century, the madrassa was introduced, a school that was built independently from the mosque, such as al-Qarawiyyin, founded in 859 CE. They were also the first to make the Madrassa system a public domain under the control of the Caliph.
Under the Ottomans, the towns of Bursa and Edirne became the main centers of learning. The Ottoman system of Külliye, a building complex containing a mosque, a hospital, madrassa, and public kitchen and dining areas, revolutionized the education system, making learning accessible to a wider public through its free meals, health care and sometimes free accommodation.
In Europe, universities emerged during the 12th century; here, scholasticism was an important tool, and the academicians were called schoolmen. During the Middle Ages and much of the Early Modern period, the main purpose of schools (as opposed to universities) was to teach the Latin language. This led to the term grammar school, which in the United States informally refers to a primary school, but in the United Kingdom means a school that selects entrants based on ability or aptitude. Following this, the school curriculum has gradually broadened to include literacy in the vernacular language as well as technical, artistic, scientific and practical subjects.
Obligatory school attendance became common in parts of Europe during the 18th century. In Denmark-Norway, this was introduced as early as in 1739-1741, the primary end being to increase the literacy of the almue, i.e. the "regular people". Many of the earlier public schools in the United States and elsewhere were one-room schools where a single teacher taught seven grades of boys and girls in the same classroom. Beginning in the 1920s, one-room schools were consolidated into multiple classroom facilities with transportation increasingly provided by kid hacks and school buses.
The use of the term school varies by country, as do the names of the various levels of education within the country.
In the United Kingdom, the term school refers primarily to pre-university institutions, and these can, for the most part, be divided into pre-schools or nursery schools, primary schools (sometimes further divided into infant school and junior school), and secondary schools. Various types of secondary schools in England and Wales include grammar schools, comprehensives, secondary moderns, and city academies. In Scotland, while they may have different names, there is only one type of secondary school, although they may be funded either by the state or independently funded. School performance in Scotland is monitored by Her Majesty's Inspectorate of Education. Ofsted reports on performance in England and Estyn reports on performance in Wales.
In the United Kingdom, most schools are publicly funded and known as state schools or maintained schools in which tuition is provided for free. There are also private schools or independent schools that charge fees. Some of the most selective and expensive private schools are known as public schools, a usage that can be confusing to speakers of North American English. In North American usage, a public school is one that is publicly funded or run.
In much of the Commonwealth of Nations, including Australia, New Zealand, India, Pakistan, Bangladesh, Sri Lanka, South Africa, Kenya, and Tanzania, the term school refers primarily to pre-university institutions.
In ancient India, schools were in the form of Gurukuls. Gurukuls were traditional Hindu residential schools of learning; typically the teacher's house or a monastery. During the Mughal rule, Madrasahs were introduced in India to educate the children of Muslim parents. British records show that indigenous education was widespread in the 18th century, with a school for every temple, mosque or village in most regions of the country. The subjects taught included Reading, Writing, Arithmetic, Theology, Law, Astronomy, Metaphysics, Ethics, Medical Science and Religion.
Under the British rule in India, Christian missionaries from England, USA and other countries established missionary and boarding schools throughout the country. Later as these schools gained in popularity, more were started and some gained prestige. These schools marked the beginning of modern schooling in India and the syllabus and calendar they followed became the benchmark for schools in modern India. Today most of the schools follow the missionary school model in terms of tutoring, subject / syllabus, governance etc.with minor changes. Schools in India range from schools with large campuses with thousands of students and hefty fees to schools where children are taught under a tree with a small / no campus and are totally free of cost. There are various boards of schools in India, namely Central Board for Secondary Education (CBSE), Council for the Indian School Certificate Examinations (CISCE), Madrasa Boards of various states, Matriculation Boards of various states, State Boards of various boards, Anglo Indian Board, and so on. The typical syllabus today includes Language(s), Mathematics, Science - Physics, Chemistry, Biology, Geography, History, General Knowledge, Information Technology / Computer Science etc.. Extra curricular activities include physical education / sports and cultural activities like music, choreography, painting, theater / drama etc.
In much of continental Europe, the term school usually applies to primary education, with primary schools that last between four and nine years, depending on the country. It also applies to secondary education, with secondary schools often divided between Gymnasiums and vocational schools, which again depending on country and type of school educate students for between three and six years. In Germany students graduating from Grundschule are not allowed to directly progress into a vocational school, but are supposed to proceed to one of Germany's general education schools such as Gesamtschule, Hauptschule, Realschule or Gymnasium. When they leave that school, which usually happens at age 15-19 they are allowed to proceed to a vocational school. The term school is rarely used for tertiary education, except for some upper or high schools (German: Hochschule), which describe colleges and universities.
In Eastern Europe modern schools (after World War II), of both primary and secondary educations, often are combined, while secondary education might be split into accomplished or not. The schools are classified as middle schools of general education and for the technical purposes include "degrees" of the education they provide out of three available: the first - primary, the second - unaccomplished secondary, and the third - accomplished secondary. Usually the first two degrees of education (eight years) are always included, while the last one (two years) gives option for the students to pursue vocational or specialized educations.
In North America, the term school can refer to any educational institution at any level, and covers all of the following: preschool (for toddlers), kindergarten, elementary school, middle school (also called intermediate school or junior high school, depending on specific age groups and geographic region), high school (or in some cases senior high school), college, university, and graduate school.
In the United States, school performance through high school is monitored by each state's department of education. Charter schools are publicly funded elementary or secondary schools that have been freed from some of the rules, regulations, and statutes that apply to other public schools. The terms grammar school and grade school are sometimes used to refer to a primary school. In addition, there are tax-funded magnet schools which offer different programs and instruction not available in traditional schools.
In Western Africa, the term school can refer to "bush" schools, Quranic schools, or apprenticeships. These schools include formal and informal learning.
Bush schools are training camps that pass down cultural skills, traditions, and knowledge to their students. Bush schools are semi similar to traditional western schools because they are separated from the larger community. These schools are located in forests outside of the towns and villages, and the space used is solely for these schools. Once the students have arrived in the forest, they are not allowed to leave until their training is complete. Visitors are absolutely prohibited from these areas. Instead of being separated by age, Bush schools are separated by gender. Women and girls are not allowed to enter the territory of the boys' bush school and vice versa. Boys receive training in cultural crafts, fighting, hunting, and community laws among other subjects. Girls are trained in their own version of the boys' bush school. They practice domestic affairs such as cooking, childcare, as well as how to be a good wife. Their training is focused on how to be a proper woman by societal standards.
Qur'anic schools are the principle way of teaching the Quran and knowledge of the Islamic faith. These schools also fostered literacy and writing during the time of colonization. Today, the emphasis is on the different levels of reading, memorizing, and reciting the Quran. Attending a Qur'anic school is how children become recognized members of the Islamic faith. Children often attend state schools and a Qur'anic school.
In Mozambique, specifically, there are two kinds of Qur'anic schools. They are the tariqa based and the Wahhabi-based schools. What makes these schools different is who controls them. Tariqa schools are controlled at the local level while the Wahhabi are controlled by the Islamic Council. Within the Qur'anic school system, there are levels of education. They range from a basic level of understanding, called chuo and kioni in local languages, to the most advanced which is called ilimu.
In Nigeria, the term school broadly covers daycares, nursery schools, primary schools, secondary schools and tertiary institutions. Primary and secondary schools are either privately funded by religious institutions and corporate organisations, or government-funded. Government-funded schools are commonly referred to as public schools. Students spend 6 years in primary school, 3 years in junior secondary school and 3 years in senior secondary school. The first 9 years of formal schooling is compulsory under the Universal Basic Education Program (UBEC). Tertiary institutions include public and private universities, polytechnics, and colleges of education. Universities can be funded by the federal government, state governments, religious institutions or individuals and organisations.
Many schools are owned or funded by states. Private schools operate independently from the government. Private schools usually rely on fees from families whose children attend the school for funding; however, sometimes such schools also receive government support (for example, through School vouchers). Many private schools are affiliated with a particular religion; these are known as parochial schools.
When designing a school, factors that need to be decided include:
Schools are organized spaces purposed for teaching and learning. The classrooms, where teachers teach and students learn, are of central importance. Classrooms may be specialized for certain subjects, such as laboratory classrooms for science education and workshops for industrial arts education.
Typical schools have many other rooms and areas, which may include:
The safety of staff and students is increasingly becoming an issue for school communities, an issue most schools are addressing through improved security. Some have also taken measures such as installing metal detectors or video surveillance. Others have even taken measures such as having the children swipe identification cards as they board the school bus. For some schools, these plans have included the use of door numbering to aid public safety response.[clarification needed]
Other security concerns faced by schools include bomb threats, gangs, and vandalism.
School health services are services from medical, teaching and other professionals applied in or out of school to improve the health and well-being of children and in some cases whole families. These services have been developed in different ways around the globe but the fundamentals are constant: the early detection, correction, prevention or amelioration of disease, disability and abuse from which school-aged children can suffer.
Some schools offer remote access to their classes over the Internet. Online schools also can provide support to traditional schools, as in the case of the School Net Namibia. Some online classes also provide experience in a class, so that when people take them, they have already been introduced to the subject and know what to expect, and even more classes provide High School/College credit allowing people to take the classes at their own pace. Many online classes cost money to take but some are offered free.
Internet-based distance learning programs are offered widely through many universities. Instructors teach through online activities and assignments. Online classes are taught the same as physically being in class with the same curriculum. The instructor offers the syllabus with their fixed requirements like any other class. Students can virtually turn their assignments in to their instructors according to deadlines. This being through via email or in the course webpage. This allowing students to work at their own pace, yet meeting the correct deadline. Students taking an online class have more flexibility in their schedules to take their classes at a time that works best for them. Conflicts with taking an online class may include not being face to face with the instructor when learning or being in an environment with other students. Online classes can also make understanding the content difficult, especially when not able to get in quick contact with the instructor. Online students do have the advantage of using other online sources with assignments or exams for that specific class. Online classes also have the advantage of students not needing to leave their house for a morning class or worrying about their attendance for that class. Students can work at their own pace to learn and achieve within that curriculum.
The convenience of learning at home has been a major attractive point for enrolling online. Students can attend class anywhere a computer can go - at home, a library or while traveling internationally. Online school classes are designed to fit your needs, while allowing you to continue working and tending to your other obligations. Online school education is divided into three subcategories: Online Elementary School, Online Middle School, Online High school.
As a profession, teaching has levels of work-related stress (WRS) that are among the highest of any profession in some countries, such as the United Kingdom and the United States. The degree of this problem is becoming increasingly recognized and support systems are being put into place.
Stress sometimes affects students more severely than teachers, up to the point where the students are prescribed stress medication. This stress is claimed to be related to standardized testing, and the pressure on students to score above average.See Cram school.
According to a 2008 mental health study by the Associated Press and mtvU, eight in 10 college students[where?] said they had sometimes or frequently experienced stress in their daily lives. This was an increase of 20% from a survey five years previously. 34 percent had felt depressed at some point in the past three months, 13 percent had been diagnosed with a mental health condition such as an anxiety disorder or depression, and 9 percent had seriously considered suicide.
Schools and their teachers have always been under pressure - for instance, pressure to cover the curriculum, to perform well in comparison to other schools, and to avoid the stigma of being "soft" or "spoiling" toward students. Forms of discipline, such as control over when students may speak, and normalized behaviour, such as raising a hand to speak, are imposed in the name of greater efficiency. Practitioners of critical pedagogy maintain that such disciplinary measures have no positive effect on student learning. Indeed, some argue that disciplinary practices detract from learning, saying that they undermine students' individual dignity and sense of self-worth - the latter occupying a more primary role in students' hierarchy of needs.
