K–12 refers to the sum of primary and secondary education in several countries, including the United States, Canada, South Korea, Turkey, the Philippines, Egypt, Australia, and Iran. The term is a short form for the publicly supported school grades prior to college. These grades are kindergarten (K) and the 1st through the 12th grade (1–12).

Overview

K–12 education is a comprehensive system that encompasses the entirety of a child's formal education prior to entering higher education. The system is designed to provide a foundational education that prepares students for college, vocational training, or entry into the workforce.

Kindergarten

Kindergarten is the first stage of formal education, typically for children aged 5 to 6. It focuses on basic skills such as literacy, numeracy, and social interaction. Kindergarten serves as a transition from home or preschool to the more structured environment of elementary school.

Elementary School

Elementary school usually covers grades 1 through 5 or 6, depending on the region. The curriculum includes fundamental subjects such as reading, writing, mathematics, science, and social studies. The goal is to build a strong foundation in these core areas while also fostering critical thinking and problem-solving skills.

Middle School

Middle school, also known as junior high school in some regions, typically includes grades 6 through 8. This stage serves as a bridge between elementary school and high school, introducing students to more complex subjects and a greater degree of independence. Students begin to explore subjects in more depth, including advanced mathematics, science, and humanities.

High School

High school encompasses grades 9 through 12 and is the final stage of K–12 education. Students are offered a wider range of subjects and electives, allowing them to specialize in areas of interest. High school education aims to prepare students for post-secondary education or vocational training. It often includes standardized testing and assessments that are critical for college admissions.

Curriculum

The K–12 curriculum varies by country and region but generally includes a mix of core subjects and electives. Core subjects typically include:

• Mathematics
• Science
• English language arts
• Social studies
• Physical education

Electives may include:

• Foreign languages
• Arts (such as music, theater, and visual arts)
• Technology and computer science
• Vocational education

Educational Standards

Educational standards in K–12 are often set by government agencies or educational boards. These standards define the learning goals for each grade level and subject area. In the United States, for example, the Common Core State Standards Initiative provides a set of academic standards in mathematics and English language arts.

Challenges and Reforms

K–12 education faces numerous challenges, including disparities in funding, access to resources, and educational outcomes. Reforms often focus on improving teacher quality, updating curricula, and integrating technology into the classroom. Efforts to address these challenges include initiatives to reduce class sizes, increase teacher salaries, and provide equitable access to educational resources.
