There are many classifications of education. One of them depends on the institutional framework and distinguishes between formal, non-formal, and informal education. Another classification includes distinct levels of education based on factors like the student's age and the complexity of the content. Further categories focus on the topic, teaching method, medium used, and funding.
Formal, non-formal, and informal The most common division is between formal,
non-formal, and
informal education. Formal education happens in a complex institutional framework. Such frameworks have a chronological and hierarchical order: the modern schooling system has classes based on the student's age and progress, extending from primary school to university. Formal education is usually controlled and guided by the
government. It tends to be
compulsory up to a certain age. Non-formal and informal education take place outside the formal schooling system. Non-formal education is a middle ground. Like formal education, it is organized, systematic, and carried out with a clear purpose, as in the case of
tutoring, fitness classes, and the
scouting movement. Informal education happens in an unsystematic way through daily experiences and exposure to the environment. Unlike formal and non-formal education, there is usually no designated authority figure responsible for teaching. Informal education takes place in many different settings and situations throughout one's life, usually in a spontaneous way. This is how children learn their
first language from their parents and how people learn to prepare a dish by cooking together. Some theorists distinguish the three types based on the location of learning: formal education takes place in
school, non-formal education happens in places that are not regularly visited, like museums, and informal education occurs in places of everyday routines. There are also differences in the source of motivation. Formal education tends to be driven by
extrinsic motivation for external rewards. In non-formal and informal education, enjoyment of the learning process usually provides intrinsic motivation. The distinction between the three types is normally clear, but some forms of education do not easily fall into one category. In primitive cultures, most education occurred informally, and there was little distinction between educational activities and other activities. Instead, the whole environment acted as a form of school, and most adults acted as teachers. Informal education is often not efficient enough to teach large quantities of
knowledge. To do so, a formal setting and well-trained teachers are usually required. This was one of the reasons why formal education became increasingly important throughout history. In this process, the experience of education and the discussed topics became more abstract and removed from daily life while more emphasis was put on grasping general patterns and concepts instead of observing and imitating particular forms of behavior.
Levels in Japan Types of education are often divided into levels or stages. The most influential framework is the
International Standard Classification of Education, maintained by the
United Nations Educational, Scientific and Cultural Organization (UNESCO). It covers both formal and non-formal education and distinguishes levels based on the student's age, the duration of learning, and the complexity of the discussed content. Further criteria include entry requirements, teacher qualifications, and the intended outcome of successful completion. The levels are grouped into
early childhood education (level 0),
primary education (level 1),
secondary education (levels 2–3), post-secondary non-tertiary education (level 4), and
tertiary education (levels 5–8). Early childhood education, also known as
preschool education or nursery education, begins with birth and lasts until the start of
primary school. It follows the holistic aim of fostering early childhood development across the physical, mental, and social domains. It plays a key role in socialization and
personality development and includes various basic skills in the areas of communication, learning, and problem-solving. This way, it aims to prepare children for their entry into primary education. Preschool education is usually optional, but in some countries, such as Brazil, it is mandatory starting from the age of four. Primary (or elementary) education usually starts between the ages of five and seven and lasts for four to seven years. It has no further entry requirements, and its main goal is to teach basic skills in reading, writing, and mathematics. It also covers core knowledge in other fields, such as
history,
geography, the
sciences,
music, and
art. A further aim is to foster personal development. Today, primary education is compulsory in almost all countries, and over 90% of all primary-school-age children worldwide attend primary school. Secondary education follows primary education and usually covers the ages of 12 to 18 years. It is commonly divided into lower secondary education (
middle school or junior high school) and upper secondary education (
high school, senior high school, or
college depending on the country). Lower secondary education normally has the completion of primary school as its entry requirement. It aims to extend and deepen learning outcomes, is more focused on subject-specific
curricula, and has teachers who specialize in only one or a few subjects. One of its aims is to familiarize students with the basic theoretical concepts in the different subjects. This helps create a solid basis for
lifelong learning. In some cases, it also includes basic forms of
vocational training. Lower secondary education is compulsory in many countries in Central and East Asia, Europe, and America. In some countries, it is the last stage of compulsory education. Mandatory lower secondary education is not as prevalent in Arab states, sub-Saharan Africa, and South and West Asia. Upper secondary education starts roughly at the age of 15 and aims to provide students with the skills and knowledge needed for employment or tertiary education. Its requirement is usually the completion of lower secondary education. Its subjects are more varied and complex and students can often choose between a few subjects. Its successful completion is commonly tied to a formal qualification in the form of a
high school diploma. Some types of education after secondary education do not belong to tertiary education and are categorized as post-secondary non-tertiary education. They are similar in complexity to secondary education but tend to focus more on vocational training to prepare students for the job market. in Russia In some countries, tertiary education is used as a synonym of
higher education, while in others, tertiary education is the wider term. Tertiary education expands upon the foundations of secondary education but has a more narrow and in-depth focus on a specific field or subject. Its completion leads to an
academic degree. It can be divided into four levels: short-cycle tertiary,
Bachelor's,
Master's, and
doctoral level education. These levels often form a hierarchical structure with later levels depending on the completion of previous levels. Short-cycle tertiary education focuses on practical matters. It includes advanced vocational and professional training to prepare students for the job market in specialized professions. Bachelor's level education, also referred to as
undergraduate education, tends to be longer than short-cycle tertiary education. Universities usually offer it as an intermediate academic certification, namely a bachelor's degree. Master's level education is more specialized than undergraduate education. Many programs require independent research in the form of a master's thesis for successful completion. Doctoral level education leads to an advanced research qualification, normally in the form of a doctor's degree, such as a
Doctor of Philosophy (PhD). It usually requires the submission of a substantial academic work, such as a
dissertation. More advanced levels include
post-doctoral studies and
habilitation. Successful participation in formal education usually results in a form of certification that is required for higher levels of education and
certain professions. Undetected
cheating in exams, for example, by using a
cheat sheet, threatens to undermine this system if unqualified students are certified. In most countries, primary and secondary education are free of charge. There are significant global differences in the cost of tertiary education. A few countries, like Sweden, Finland, Poland, and Mexico, offer tertiary education for free or at a low cost. In some countries, like the United States and Singapore, tertiary school
tuition fees are high and students often have to take substantial loans to afford their studies. High costs of education can constitute a significant barrier to students in
developing countries whose families may be unable to afford school fees, uniforms, and textbooks.
Others The academic literature discusses many other types of education and distinguishes between
traditional and
alternative education. Traditional education concerns long-established and mainstream schooling practices. It uses teacher-centered education and takes place in a well-regulated school environment. Regulations cover many aspects of education, such as the curriculum and the timeframe when classes start and end. Alternative education is an umbrella term for forms of schooling that differ from the mainstream traditional approach. Differences may include learning environment, subjects, or the teacher-student relationship. Alternative schooling is characterized by voluntary participation, relatively small class and school sizes, and personalized instruction. This often results in a more welcoming and emotionally safe atmosphere. Alternative education encompasses many types like
charter schools and special programs for problematic or gifted children. It also includes
homeschooling and
unschooling. There are many
alternative schooling traditions, like
Montessori schools,
Waldorf schools,
Round Square schools,
Escuela Nueva schools, free schools, and
democratic schools. Alternative education also includes
indigenous education, which focuses on the transmission of knowledge and skills from an indigenous heritage and employs methods like narration and storytelling. Further types of alternative schools include
gurukul schools in India,
madrasa schools in the Middle East, and
yeshivas in Jewish tradition. Some distinctions focus on who receives education. Categories by the age of the learner are childhood education, adolescent education, adult education, and elderly education. Categories by
biological sex of the students include
single-sex education and
mixed-sex education.
Special education is education that is specifically adapted to meet the unique needs of students with
disabilities. It covers various forms of impairments on the
intellectual, social, communicative, and
physical levels. It aims to overcome the challenges posed by these impairments. This way, it provides the affected students with access to an appropriate educational structure. When understood in the broadest sense, special education also includes education for very
gifted children who need adjusted curricula to reach their fullest potential. Classifications based on the teaching method include teacher-centered education, in which the teacher takes center stage in providing students with information, and
student-centered education, in which students take on a more active and responsible role in shaping classroom activities. For conscious education, learning and teaching happen with a clear purpose in mind. Unconscious education occurs on its own without being consciously planned or guided. This may happen in part through the
personality of teachers and adults, which can have indirect effects on the development of the student's personality.
Evidence-based education uses scientific studies to determine which methods of education work best. Its goal is to maximize the effectiveness of educational practices and policies by ensuring that they are informed by the best available
empirical evidence. It includes evidence-based teaching, evidence-based learning, and school effectiveness research.
Autodidacticism, or self-education, happens without the guidance of teachers and institutions. It mainly occurs in adult education and is characterized by the freedom to choose what to study and when, which can make it a more fulfilling learning experience. The lack of structure and guidance can result in aimless learning, and the absence of
external feedback may lead autodidacts to develop false ideas and inaccurately assess their learning progress. Autodidacticism is closely related to
lifelong education, which is an ongoing learning process throughout a person's entire life. Categories of education based on the subject include
science education,
language education,
art education,
religious education,
physical education, and
sex education. Special mediums, such as radio or websites, are used in
distance education. Examples include e-learning (use of computers),
m-learning (use of mobile devices), and online education. They often take the form of
open education, in which courses and materials are made available with minimal barriers to access. They contrast with regular classroom or on-site education. Some forms of online education are not open education, such as full online degree programs offered by some universities. State education, also referred to as
public education, is funded and controlled by the government and available to the general public. It normally does not require tuition fees and is thus a form of
free education.
Private education, by contrast, is funded and managed by private institutions. Private schools often have a more selective admission process and offer paid education by charging tuition fees. A more detailed classification focuses on the social institution responsible for education, like family, school, civil society, state, and church. Compulsory education is education that people are legally required to receive. It concerns mainly children who need to visit school up to a certain age. It contrasts with voluntary education, which people pursue by personal choice without a legal requirement. == Role in society ==
