Seventy-five students scored higher than 560 points in the high school entrance examination, and 103 students received full marks in a single subject, with an overall average score of 550 in their grade - this is the performance of the 13th middle school branch in the 2016 high school entrance examination, which is very competitive even in Haidian District. The 2017 high school entrance examination results of the 13th Middle School Branch are in stark contrast, with the number of students with a score of 560 or more becoming 44, and the number of students with a full score in a single subject becoming 57.

In 2017, the difficulty of the examination questions is one of the reasons for the halving of the number of top students, and the 2014 education reform in Xicheng District is also very related to it. However, although the number of top students is not so outstanding, the overall strength of the branch of the 13th Middle School is still strong, with an average score of 538 ranking first in Xicheng, the average score of cultural courses can rank in the top five in Haidian District, and the online rate of exemplary high schools is also more than 60%.

The branch of 13th Middle School does not have a high school, it is a simple junior high school. Thirteen points adopts the traditional large class system, with nearly 40 students in each class of more than 20 teaching classes. There are more than 110 faculty members in the school, and on the surface, the teacher-student ratio of 1:10 is a little thin, but the teaching force of the 13th middle school branch is not weak, and there are 25 district-level subject leaders or backbone teachers in the teaching team, and the proportion of teachers at the first level and above is about 60%.

In recent years, at least 240 students from the 13th Middle School branch will complete their enrollment through the school district's allocation every year. In 2018, the number of district-wide allocation places will also rise to 60. The placement test of the 13th Middle School branch is conducted after admission, and it is usually divided into two experimental classes in mathematics and English. The experimental class of the 13th Middle School Branch does not implement a turnover system, and there will be no personnel changes in the three academic years.

The merit-based class division enables the 13th Middle School branch to produce high-level students, and the tense academic style allows the students in the non-experimental class to have good test-taking ability, ensuring that the average level of the school is always in the forefront of Xicheng District. The 13th Middle School Branch is known as the "Devil's Training Camp" in the community, leaving many parents with the stereotype of "more homework" and "teachers are responsible", and many students admit that it is difficult for them to complete their homework before 22:00, and the proportion of students who can complete the task before 21:00 is very low. On the whole, the first and second stages of junior high school are relatively easy, and the preparation for the third junior high school is full of test-taking training, and its learning mode is relatively close to that of Hengshui Middle School, which is a common practice in many incomplete middle schools.

Coherent teaching and innovation is the trend of education reform in recent years, but the branch of the third middle school has no high school, and the education reform can only be reflected in innovation. At present, the school has set up more than 20 elective courses, including psychology, Chinese studies, scientific experiments, reading, etc. The 13th Middle School branch does not allow students to create club organizations, but in recent years, it has opened student activity courses, and the official announcement has set up more than 30 courses such as dance, painting, chess, vocal music, etc., although its openness is not as good as that of student self-organization, but it is much easier than the teaching course, and plays a little role in making up for it. Visits to museums, lectures, autumn outings, Sutuo and other activities are also gradually increasing, but the amount of activities is not at the same level as that of Haidian Pioneer School.

Although the curriculum has been reformed, the atmosphere of the 13th Middle School is still conservative. In contrast, the campus renovation plan proposed by the university in 2011 was more popular with students. At present, an indoor basketball court has been built on the campus, teaching buildings, laboratories, and libraries have also been renovated, and various electronic devices have been gradually completed. However, the project did not involve expansion, and the campus covers just over 8,000 square meters, which is probably the highest student density of any secondary school in Beijing, and since the school is located within the second ring road, it is not easy to improve the crowded campus environment.

The 13th Middle School Branch, formerly known as Beijing No. 106 Middle School, was merged with the 13th Middle School in 1998 and has no relationship with the 13th Middle School since then. It should also be noted that there is no canteen at the 13th Middle School, and the catering partners contacted by the school are not very good at cooking, and the crowded campus environment does not have the conditions to build student dormitories, so there is no common public boarding route.
