Elementary education is also known as primary education. This is the first stage in the formal education system and begins at the age of 5 to 7 and ends at age 11 to 13. In countries like the United Kingdom, the term primary is replaced with elementary. However, in the US, the term primary refers to the first three years of elementary education- i.e., grades 1 to 3. Elementary education is also referred to as a form of preschool for children ages 3 to 5 or 6 and is followed by secondary education. Despite the cultural and social differences among different countries, the curriculum and objective of elementary education remain the same. All nations are committed to enhancing mass education. For this, an increasing agreement can be seen among nations to the effect that citizenship is one of the main goals of elementary education. In the curriculum, the emphasis is laid on reading, writing, arithmetic skills, and other social studies and science skills.
