1. Preschool education
Preschool education or Infant education is the provision of education for children before the commencement of statutory and obligatory education, usually between the ages of zero and three or five, depending on the jurisdiction.
In British English, nursery school or simply "nursery" or playgroup is the usual term for preschool education, although the term preschool is also commonly used. In the United States preschool and Pre-K are used, while "nursery school" is an older term.
Preschool work is organized within a framework that professional educators create. The framework includes structural (administration, class size, student–teacher ratio, services, etc.), process (quality of classroom environments, teacher-child interactions, etc.), and alignment (standards, curriculum, assessments) components that are associated with each individual unique child that has both social and academic outcomes. At each age band, an appropriate curriculum should be followed. For example, it would be normal to teach a child how to count to 10 after the age of four. Arguably the first pre-school institution was opened in 1816 by Robert Owen in New Lanark, Scotland. The Hungarian countess Theresa Brunszvik followed in 1828. In 1837, Friedrich Fröbel opened one in Germany, coining the term "kindergarten".
2. Primary education

Primary (or elementary) education consists of the first 5–7 years of formal, structured education. In general, primary education consists of six or eight years of schooling starting at the age of five or six, although this varies between, and sometimes within, countries. Globally, around 89% of primary-age children are enrolled in primary education, and this proportion is rising.[2] Under the Education For All programs driven by UNESCO, most countries have committed to achieving universal enrollment in primary education by 2015, and in many countries, it is compulsory for children to receive primary education. The division between primary and secondary education is somewhat arbitrary, but it generally occurs at about eleven or twelve years of age. Some education systems have separate middle schools, with the transition to the final stage of secondary education taking place at around the age of fourteen. Schools that provide primary education, are mostly referred to as primary schools. Primary schools in these countries are often subdivided into infant schools and junior school.
3. Secondary education

In most contemporary educational systems of the world, secondary education comprises the formal education that occurs during adolescence. It is characterized by transition from the typically compulsory, comprehensive primary education for minors, to the optional, selective tertiary, "post-secondary", or "higher" education (e.g., university, vocational school for adults. Depending on the system, schools for this period, or a part of it, may be called secondary or high schools, gymnasiums, lyceums, middle schools, colleges, or vocational schools. The exact meaning of any of these terms varies from one system to another. The exact boundary between primary and secondary education also varies from country to country and even within them, but is generally around the seventh to the tenth year of schooling. Secondary education occurs mainly during the teenage years. In the United States, Canada and Australia primary and secondary education together are sometimes referred to as K-12 education, and in New Zealand Year 1-13 is used. The purpose of secondary education can be to give common knowledge, to prepare for higher education or to train directly in a profession.
The emergence of secondary education in the United States did not happen until 1910, caused by the rise in big businesses and technological advances in factories (for instance, the emergence of electrification), that required skilled workers. In order to meet this new job demand, high schools were created and the curriculum focused on practical job skills that would better prepare students for white collar or skilled blue collar work. This proved to be beneficial for both the employer and the employee, because this improvement in human capital caused employees to become more efficient, which lowered costs for the employer, and skilled employees received a higher wage than employees with just primary educational attainment.
In Europe, the grammar school or academy existed from as early as the 16th century; public schools or fee-paying schools, or charitable educational foundations have an even longer history.
4. Higher education
Main article: Higher education
The University of Cambridge is an institute of higher learning.
Higher education, also called tertiary, third stage, or post secondary education, is the non-compulsory educational level that follows the completion of a school providing a secondary education, such as a high school or secondary school. Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training. Colleges and universities are the main institutions that provide tertiary education. Collectively, these are sometimes known as tertiary institutions. Tertiary education generally results in the receipt of certificates, diplomas, or academic degrees.
Higher education includes teaching, research and social services activities of universities, and within the realm of teaching, it includes both the undergraduate level (sometimes referred to as tertiary education) and the graduate (or postgraduate) level (sometimes referred to as graduate school). Higher education generally involves work towards a degree-level or foundation degree qualification. In most developed countries a high proportion of the population (up to 50%) now enter higher education at some time in their lives. Higher education is therefore very important to national economies, both as a significant industry in its own right, and as a source of trained and educated personnel for the rest of the economy.
5. Adult education
Main article: Adult education
Adult education has become common in many countries. It takes on many forms, ranging from formal class-based learning to self-directed learning and e-learning. A number of career specific courses such as veterinary assisting, medical billing and coding, real estate license, bookkeeping and many more are now available to students through the Internet.
6. Alternative education
Main article: Alternative education
Alternative education, also known as non-traditional education or educational alternative, is a broad term that may be used to refer to all forms of education outside of traditional education (for all age groups and levels of education). This may include not only forms of education designed for students with special needs (ranging from teenage pregnancy to intellectual disability), but also forms of education designed for a general audience and employing alternative educational philosophies and methods.
Alternatives of the latter type are often the result of education reform and are rooted in various philosophies that are commonly fundamentally different from those of traditional compulsory education. While some have strong political, scholarly, or philosophical orientations, others are more informal associations of teachers and students dissatisfied with certain aspects of traditional education. These alternatives, which include charter schools, alternative schools, independent schools, homeschooling and autodidacticism vary widely, but often emphasize the value of small class size, close relationships between students and teachers, and a sense of community.
7. Indigenous education
Main article: Indigenous education
Increasingly, the inclusion of indigenous models of education (methods and content) as an alternative within the scope of formal and nonformal learning systems, has come to represent a significant factor contributing to the success of those members of indigenous communities who choose to access these systems, both as students/learners and as teachers/instructors.
