A primary school is an educational institution that provides the first stage of formal education, typically for children aged 5 to 11 years. It focuses on foundational subjects such as reading, writing, mathematics, science, and social studies. Primary schools aim to develop basic academic skills, as well as social and emotional skills, in young learners. This stage of education serves as the groundwork for further learning in secondary and higher education. In many countries, primary school is compulsory and is considered a key part of a child's early development.

A secondary school is an educational institution that provides education to students typically between the ages of 11 or 12 and 16 or 18, depending on the country. It follows primary school and prepares students for adulthood, offering both general education and specialized subjects. Secondary schools may offer different types of programs, including academic tracks, vocational training, or a combination of both, depending on the region. The focus is on preparing students for further education, work, or other life pursuits.

A university is an institution of higher education that offers a wide range of academic programs, including undergraduate, graduate, and sometimes professional degrees. Universities typically have multiple departments or faculties, each specializing in different fields of study. In addition to providing bachelor's degrees, universities offer advanced degrees such as master's and doctoral programs. Universities are also centers for research, where students and faculty conduct studies that contribute to the advancement of knowledge. Many universities have a larger student body and offer a broader array of extracurricular activities compared to colleges.
