secondary

Secondary refers to something that is less important or subordinate to something else. In the context of education, secondary education refers to the stage of education that comes after primary education and before tertiary education. This stage typically covers the ages of 12 to 18 and is often divided into lower secondary and upper secondary levels.

At the lower secondary level, students are introduced to a wider range of subjects and are expected to develop more advanced skills in areas such as critical thinking, problem-solving, and communication. They may also be given more opportunities to participate in extracurricular activities and develop leadership skills.

At the upper secondary level, students typically focus on preparing for higher education or entering the workforce. They may choose to specialize in certain subjects or pursue vocational training. In some countries, upper secondary education is compulsory, while in others it is optional.

Overall, secondary education plays a crucial role in preparing students for their future careers and helping them develop the skills and knowledge they need to succeed in life. While it may be seen as secondary to primary education or tertiary education, it is nonetheless an important and essential part of the education system.
