A lot of Bưởi alumni became renowned political leaders and cultural figures in many areas of Vietnamese society such as Nguyễn Văn Cừ – the fourth general secretary of Communist Party of Vietnam, Phạm Văn Đồng – the first prime minister of North Vietnam and united Vietnam, Nguyễn Cao Kỳ- former vice president and prime minister of South Vietnam, Kaysone Phomvihane- former leader of the Lao People's Revolutionary Party, Prince Souphanouvong- the first president of Laos.

After Japan overthrew France, on 12 June 1945, the northern king's special envoy Phan Kế Toại decided to change the school's name to Chu Van An – named after the most well-respected teacher in Vietnamese history Chu Văn An, and appointed professor Nguyễn Gia Tường to the principal position.

Since 2019, Chu Van An High School has been the first school in Hanoi and Vietnam to be a member of the Cambridge Assessment International Education (CAIE) organization, making it eligible to train students under the dual degree programme (Vietnamese National Diploma & Cambridge International A-Level).

Every year, the school receives over 3000 applications from Hanoi and other Northern Vietnamese provinces to Thanh Hoa, out of which only 500 to 600 would be admitted.

Applicants are required to take an entrance exam conducted by the Hanoi Department of Education and Training.

Applicants who prefer to be trained under the dual degree programme, along with taking the entrance exam will also have to take other exams in English such as Mathematics, Physics, Chemistry and English (Writing & Speaking skills) to be admitted in dual degree classes.

Chu Van An High School currently has 1 campus, which lies next to West Lake between Nguyễn Đình Thi Road and Thụy Khuê Street.
