A primary school, junior school (in UK), elementary school or grade school (in US & Canada) is a school for children from about four to eleven years old, in which they receive primary or elementary education. It can refer to both the physical structure (buildings) and the organisation. Typically it comes after preschool, and before secondary school.
The International Standard Classification of Education considers primary education as a single phase where programmes are typically designed to provide fundamental skills in reading, writing and mathematics and to establish a solid foundation for learning. This is ISCED Level 1: Primary education or first stage of basic education. 
During Greek and Roman times, boys were educated by their mothers until the age of seven, then according to the culture of their location and times, would start a formal education. In Sparta until twelve, it would be at a military academy building up physical fitness and combat skills, but also reading, writing and arithmetic :25 while in Athens the emphasis would be on understanding the laws of the polis, reading, writing, arithmetic and music with gymnastics and athletics,:29,30 and learning the moral stories of Homer. Girls received all their education at home. In Rome the primary school was called the ludus; the curriculum developed over the centuries featuring the learning of both Latin and Greek. In AD 94, Quintilian published the systematic educational work, Institutio oratoria.:68 He distinguished between teaching and learning, and that a child aged between 7 and 14 learned by sense experience, learns to form ideas, develops language and memory. He recommended that teachers should motivate their pupils by making the teaching interesting, rather than by corporal punishment.:70 The trivium (grammar, rhetoric and logic) and quadrivium (arithmetic, geometry, astronomy and music) were legacies of the Roman curriculum. :88
As the Roman influence waned the great cathedral schools were established to provide a source of choristers and clergy. Kings School, Canterbury dates from 597. The Council of Rome in 853 specified that each parish should provide elementary education: religious ritual but also reading and writing Latin.:81 The purpose of education was pass on salvation not social change. The church had a monopoly on education and the feudal lords concurred and allowed their sons to be educated at the few church schools. The economy was agrarian and the children of serfs started work as soon as they were able. It was a truth that man was created by God in the image of Adam with his share of original sin and a boy was born sinful. Only the teaching of the church and the sacraments could redeem him.:77,85 The parishes provide elementary education- but had no requirement to provide it to every child. The need was to produce priests, and in a stable kingdom such as that of Charlemagne, administrators with elementary writing skills in Latin and the arithmetic needed to collect taxes and administer them. Alcuin (735–804) developed teaching material that were based on the catechetical method- repeating and memorizing questions and answers, though often not understanding. These skills were also needed in the great abbeys such as Cluny. There was a divergence between the needs of town and monasteries and we see the development of parish, chantry, monastic and cathedral schools. With the entry of women into church life, convents were established and with them convent schools. Girls entered here at the age of eight and were taught Latin grammar, religious doctrine and music, and the womens arts of spinning, weaving, tapestry, painting and embroidery.:84 Bede entered the monastic school at Jarrow at the age of seven and became a writer and historian. Chantry schools were the result of a charitable donations and educated the poor. Parishes had to have a school from 804, and cathedrals had to establish schools after the Lateran Council of 1179. Elementary education was mainly to teach the Latin needed for the trivium and the quadrivium that formed the basis of the secondary curriculum.
While Humanism had a great change on the secondary curriculum, the primary curriculum was unaffected.  It was believed that by studying the works of the greats, ancients who had governed empires, one became fit to succeed in any field. Renaissance boys from the age of five learned Latin grammar using the same books as the Roman child. There were the grammars of Donatus and Priscian followed by Caesar's Commentaries and then St Jerome's Latin Vulgate.
Wealthy boys were educated by tutors. Others were educated in schools attached to the parishes, cathedrals or abbeys. From the 13th century, wealthy merchants endowed money for priests to "establish as school to teach grammar". These early grammar schools were to teach basic, or elementary grammar, to boys. No age limit was specified. Early examples in England included Lancaster Royal Grammar School, Royal Latin School, Buckingham, and Stockport Grammar School. The Reformation and the Dissolution of the Monasteries (1548) disrupted the funding of many schools. The schools petitioned the King, Edward VI, for an endowment. Examples of schools receiving endowments are King Edward VI Grammar School, Louth, King Edward VI Grammar School, Norwich and King Edward VI School, Stratford-upon-Avon, where William Shakespeare was thought to be pupil from the age of 7 to 14.
Though the Grammar schools were set up to deliver elementary education, they did require their entrants to have certain skills. They expected their entrants to already be able to read and write in the vernacular. There was a need
Certain movements in education had a relevance in all of Europe and its diverging colonies. The Americans were interested in the thoughts of Pestalozzi, Joseph Lancaster, Owen:208 and the Prussian schools.:4

|4||Post-secondary non-tertiary education||Programmes providing learning experiences that build on secondary education and prepare for labour market entry or tertiary education. The content is broader than secondary but not as complex as tertiary education.||Level 4: Post-secondary non-tertiary education|
|5||Short-cycle tertiary education||Short first tertiary programmes that are typically practically based, occupationally specific and prepare for labour market entry. These programmes may also provide a pathway to other tertiary programmes.||Level 5B: First stage of tertiary education: typically shorter, more practical/technical/occupationally specific programmes leading to professional qualifications.|
Within the English speaking world, there are three widely used systems to describe the age of the child. The first is the "equivalent ages", then countries that base their education systems on the "English model" use one of two methods to identify the year group, while countries that base their systems on the "American K–12 model" refer to their year groups as "grades". Canada also follows the American model, although its names for year groups are put the number after the grade: For instance, "Grade 1" in Canada, rather than "First Grade" in the United States. This terminology extends into research literature.
In Canada, education is a Provincial, not a Federal responsibility. For example, the province of Ontario also had a "Grade 13," designed to help students enter the workforce or post-secondary education, but this was phased out in the year 2003.

In most parts of the world, primary education is the first stage of compulsory education, and is normally available without charge, but may also be offered by fee-paying independent schools. The term grade school is sometimes used in the USA, although this term may refer to both primary education and secondary education.
The term primary school is derived from the French école primaire, which was first used in an English text in 1802. In the United Kingdom, "elementary education" was taught in "elementary schools" until 1944, when free elementary education was proposed for students over 11: there were to be primary elementary schools and secondary elementary schools;[a] these became known as primary schools and secondary schools.
In some parts of the United States, "primary school" refers to a school covering kindergarten through to second grade or third grade (K through 2 or 3); the "elementary school" includes grade three through five or grades four to six. In Canada, "elementary school" almost everywhere refers to Grades 1 through 6; with Kindergarten being referred to as "preschool."
Though often used as a synonym, "elementary school" has specific meanings in different locations.
School building design does not happen in isolation. The building (or school campus) needs to accommodate:
Each country will have a different education system and priorities. Schools need to accommodate students, staff, storage, mechanical and electrical systems, storage, support staff, ancillary staff and administration. The number of rooms required can be determined from the predicted roll of the school and the area needed.
According to standards used in the United Kingdom, a general classroom for 30 reception class or infant (Keystage 1) students needs to be 62 m2, or 55 m2 for juniors (Keystage 2). Examples are given on how this can be configured for a 210 place primary with attached 26 place nursery and two storey 420 place (two form entry) primary school with attached 26 place nursery.
The building providing the education has to fulfil the needs of: The students, the teachers, the non-teaching support staff, the administrators and the community. It has to meet general government building guidelines, health requirements, minimal functional requirements for classrooms, toilets and showers, electricity and services, preparation and storage of textbooks and basic teaching aids. An optimum school will meet the minimum conditions and will have:
Government accountants having read the advice then publish minimum guidelines on schools. These enable environmental modelling and establishing building costs. Future design plans are audited to ensure that these standards are met but not exceeded. Government ministries continue to press for the 'minimum' space and cost standards to be reduced.
The UK government published this downwardly revised space formula for primary schools in 2014. It said the floor area should be 350 m2 + 4.1 m2/pupil place. The external finishes were to be downgraded to meet a build cost of £1113/m2.
There are three main ways of funding a school: it can funded by the state through general taxation, it can be funded by a pressure group such as the mosque or the church, it can be funded by a charity or it can be funded by contributions from the parents or a combination of these methods. Day to day oversight of the school can through a board of governors, the pressure group or by the owner.
