The competition ratio is a common term to indicate the level of competition when enrolling. This index is calculated by the number of candidates registering for nguyện vọng 1 divided by the total enrollment quota of the school.
For example, a ratio of 1/4 means that for every 4 students registering, only 1 student is admitted. This is an important basis for students and parents to consider and adjust their aspirations before the exam.
Statistics from Lao Dong show that in recent years, the competition ratio of each high school in Ho Chi Minh City (region 1 - Ho Chi Minh City before merger) has always had significant fluctuations.
In 2025, the top is Tran Dai Nghia Secondary and High School with a rate of 1/4.61. This means that on average, only 1 student is admitted out of nearly 5 candidates taking the exam.
Following are a series of high-competitive schools such as Nguyen Huu Huan High School (1/2.39), Vinh Loc High School (1/2.13), Pham Van Sang High School (1/2.11).
The group of schools with a competition ratio of nearly 1/2 includes: Le Quy Don High School (1/1.95), Nguyen Thi Minh Khai High School (1/1.92), Phu Nhuan High School (1/1.79), Vo Truong Toan High School (1/1.78), Ngo Quyen High School (1/1.75) and Nguyen Huu Cau High School (1/1.73).


In 2024, the competition ratio picture has many notable points. Statistics show that up to 15 schools achieved 2.0 or higher. Leading is Nguyen Huu Huan High School with a ratio of 1/3.22, followed by Ho Thi Bi High School (1/3.06) and Nguyen Thuong Hien High School (1/2.81).
The remaining schools in the high competition ratio group in 2024 include: Le Quy Don High School (1/2.63), Pham Van Sang High School (1/2.60), Gia Dinh High School (1/2.42), Practical High School - University of Pedagogy (1/2.37), Nguyen Huu Tien High School (1/2.36), Nguyen Thi Minh Khai High School (1/2.35), Binh Hung Hoa High School (1/2.33), Bui Thi Xuan High School (1/2.19), Mac Dinh Chi High School (1/2.12), Tran Phu High School (1/2.07), Phu Nhuan High School (1/2.05) and Thanh Loc High School (1/2.03).


Reality shows that a high competition ratio does not necessarily mean an absolute high benchmark score, but it is still an important indicator of the level of competition.
The entrance exam to 10th grade for the 2026-2027 school year in Ho Chi Minh City will officially take place on 2 days, June 1st and 2nd.

In which, the Department aims to enroll more than 118,000 students into public high schools, equivalent to about 70%. The rest will study at continuing education centers, vocational schools, private schools or other directions.
It is expected that in the next few days, the Ho Chi Minh City Department of Education and Training will announce the enrollment targets for 10th grade public schools of each high school, after which, students will register their aspirations from April 22 to 28.
