Primary and secondary

Karachi's primary education system is divided into five levels: primary (grades one through five); middle (grades six through eight); high (grades nine and ten, leading to the Secondary School Certificate); intermediate (grades eleven and twelve, leading to a Higher Secondary School Certificate); and university programs leading to graduate and advanced degrees. Karachi has both public and private educational institutions. Most educational institutions are gender-based from primary to intermediate. Universities are mostly co-education.

Several of Karachi's schools, such as St Patrick's High School, St Joseph's Convent School and St Paul's English High School, are operated by Christian churches, and are among Pakistan's most prestigious schools.
