The school serves approximately 1,250 students across three grade levels (439 first-year, 422 second-year, 389 third-year as of March 2024) with a faculty of 90 teachers and 21 administrative staff. It was designated as a Science Focus School (과학중점학교) by the Ministry of Education in October 2009, offering an enhanced curriculum with 45% or more of coursework in science and mathematics across eight science subjects and four mathematics subjects. The school was also admitted to the UNESCO Associated School Network in December 2012, formalizing its international education orientation.

The school's core products and services center on its Science Focus Program, international exchange programs, and digital administrative infrastructure. The program delivers subject-centered small group exploration, research projects, and fusion science academy activities. Sister school partnerships with institutions in the USA (Walt Whitman High School), China (Lujaze, Shanghai Experimental), Russia (Vladivostok No.2, Gasforum), and Japan (Akita, Kengakko, Kyoto International) facilitate reciprocal student visits and cultural exchange. The school's digital platform includes an official website with document repositories, eBook library, online cafeteria application, school visit reservation system, and alumni network (서울고 총동창회). Technology partners include Naver Cloud (SEN School platform), School Doctor (health records), and Riroschool (academic management).

The business model is a fully government-funded public education delivery model. Tuition is free; revenue consists entirely of government operational funding from the Seoul Metropolitan Office of Education, supplemented by nominal school meal fees and voluntary development fund (발전기금) contributions from parents. Student enrollment follows the Seoul Metropolitan Office of Education's general high school assignment system, with priority placement for science-talented students. The institution operates on a 73,744㎡ campus that was relocated to Seocho-gu in June 1980. Current leadership is the 31st principal, Song Jae-beom, appointed in March 2024.
