Allameh Tabatabaei High School, under Allameh Tabatabaei Complex of Cultural and Educational units (ATCCE), is a selective independent educational institution in Tehran, Iran, with six main campuses. It was registered as a High School under the terms of the Ministry of Education Act of 26 May 1988 to prepare children for entering Iranian universities and participating in National and International Science Olympiad competitions. About 10,000 students apply for different campuses each year, but only about 5 to 10 percent of them can have the chance to be interviewed for registration. The most top-ranked students can choose to go to the Kargar Shomali or Fatemi branch since they have limited free space every year. Allameh High School is also notable for its achievements in national and international olympiads every year.
