Education in its general sense is a form of learning in which knowledge, skills, and habits of a group of people are transferred from one generation to the next through teaching, training, research, or simply through auto didacticism. Generally, it occurs through any experience that has a formative effect on the way one thinks, feels, or acts. A right to education has been created and recognized by some jurisdictions: Since 1952, Article 2 of the first Protocol to the European Convention on Human Rights obliges all signatory parties to guarantee the right to education. It does not however guarantee any particular level of education of any particular quality. At the global level, the United Nations' International Covenant on Economic, Social and Cultural Rights of 1966 guarantees this right under its Article 13.
Throughout history various governments have made it illegal to educate children privately or at home. Various totalitarian regimes, for example, have mandated indoctrination through propaganda in the Hitler Youth and propaganda in education under various communist regimes. Systems of schooling involve institutionalized teaching and learning in relation to a curriculum, which itself is established according to a predetermined purpose of the schools in the system. Schools systems were also based on people's religion giving them different curricula. In formal education, a curriculum is the set of courses and their content offered at a school or university. As an idea, curriculum stems from the Latin word for race course, referring to the course of deeds and experiences through which children grow to become mature adults. A curriculum is prescriptive, and is based on a more general syllabus which merely specifies what topics must be understood and to what level to achieve a particular grade or standard.
An academic discipline is a branch of knowledge which is formally taught, either at the university–or via some other such method. Each discipline usually has several sub-disciplines or branches, and distinguishing lines are often both arbitrary and ambiguous. Examples of broad areas of academic disciplines include the natural sciences, mathematics, computer science, social sciences, humanities and applied sciences.
Preschools
The term preschool refers to a school for children who are not old enough to attend kindergarten. It is a nursery school.
Preschool education is important because it can give a child the edge in a competitive world and education climate.While children who do not receive the fundamentals during their preschool years will be taught the alphabet, counting, shapes and colors and designs when they begin their formal education they will be behind the children who already possess that knowledge. The true purpose behind kindergarten is “to provide a child-centered, preschool curriculum for three to seven year old children that aimed at unfolding the child’s physical, intellectual, and moral nature with balanced emphasis on each of them.

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.[8] 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.
In India, compulsory education spans over twelve years, out of which children receive elementary education for 8 years. Elementary schooling consists of five years of primary schooling and 3 years of upper primary schooling. Various states in the republic of India provide 12 years of compulsory school education based on national curriculum framework designed by the National Council of Educational Research and Training.

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, with a 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 employers and employees, for the 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, grammar schools or academies date from as early as the 16th century, in the form of public schools, fee-paying schools, or charitable educational foundations, which themselves have an even longer history.
