United States
U.S. public education was conceived of in the late 18th century. In 1790, Pennsylvania became the first state to require some form of free education for everyone regardless of whether they could afford it. New York passed similar legislation in 1805. In 1820, Massachusetts became the first state to create a tuition-free high school,
Boston English.
The first K–12 public school systems appeared in the early 19th century. In the 1830s and 1840s, Ohioans were taking a significant interest in the idea of public education. At that point in time, schools were commonly operated independently of each other, with little attempt at uniformity. The Akron School Law of 1847 changed this. The city of
Akron unified the operations, curriculum and funding of local schools into a single public school district:
In 1849, the state of Ohio enacted a law modeled after the Akron law which extended the idea of school districts to cover the rest of the state.
By 1930, all 48 states had passed laws making education compulsory, and in 1965, President Lyndon B. Johnson signed the
Elementary and Secondary Education Act (ESEA), which committed the federal government to significant ongoing expenditures to each state for the purpose of sustaining local K–12 school systems. The ESEA essentially made K–12 education the law of the land.
Since its inception, public K–12 has been debated and subject to several waves of reform throughout the 20th and 21st centuries. In the 1980s, Reagan's 'A Nation at Risk' initiative included provisions requiring public education to be evaluated based on standards, and teacher pay to be based on evaluations. In the 1990s, the Goals 2000 Act and the "Improving America's Schools" act provided additional federal funding to states to bolster local K–12 systems. This was followed in the 2000s by a rigorous uptick in standards-based evaluations with the

Etymology

The expression "K–12" is a shortening of kindergarten (K) for 5–6 year olds through twelfth grade (12) for 17–18 year-olds, as the first and last
grades,
respectively, of
free education in these countries. The related term "P–12" is also occasionally used in Australia and the United States to refer to the sum of K–12 plus

education.
The accompanying image illustrates the education system in the United States. The table shows the progression of the education system starting with the basic K–12 system then progressing through post-secondary education. K–14 refers to K–12 plus two years of post-secondary where training was received from vocational-technical institutions or community or junior colleges. K–16 is 12 years of compulsory education plus a 4-year undergrad program. The K numbers refer to the years of educational attainment and continues to progress upward accordingly depending on the degree being sought.
Usage
The term is often used as a kind of shorthand to collectively refer to the entirety of primary and secondary education, as it is much easier than having to say one is referring in the aggregate to elementary, middle, and high school education. However, it is rare for a school district to actually teach all K–12 grades at one unified school campus. Even the smallest school districts try to maintain, at a minimum, a two-tier distinction between an elementary school (K–8) and a high school (9–12). Unified K–12 schools are common, however, in rural and remote areas throughout Canada. The terms "PK–12", "PreK–12", or "Pre-K–12" are sometimes used to add
pre-kindergarten.
In school website
