Lahore Garrison Education System Secretariat (LGESS) is the administrative body responsible for overseeing and managing a network of educational institutions affiliated with the Pakistan Army in Lahore and its surrounding areas.

LGESS was established to meet the educational needs of the families of Pakistan Army personnel stationed in the Lahore Garrison. 

LGESS-affiliated institutions typically offer a range of academic programs, including Matriculation (secondary school) and Intermediate (higher secondary) levels.

The curriculum is aligned with the Federal Board of Intermediate and Secondary Education (FBISE). LGESS institutions usually provide modern facilities and infrastructure, including well-equipped classrooms, science and computer labs, libraries, and sports facilities.

LGESS places a strong emphasis on discipline and instilling values such as integrity, responsibility, and patriotism in students, given its close association with the military.
