The branch of the High School Affiliated to Beijing Institute of Technology was originally the junior high school of the High School Affiliated to Science and Technology, but after 2001, it was changed to a private school and became a complete middle school. Unlike the shadow schools of many affiliated high schools, the Polytechnic branch has better grades than the main school.

The high school entrance examination score of the Polytechnic branch is basically 10-15 in Haidian District, and the overall average score will be 30-40 points higher than the district average. In 2017, the average score of the school's cultural courses was 499.03 points, 30.63 points higher than the average score of Haidian District, but the school did not announce the specific number of students in each section.

In recent years, there has been a gap between the academic threshold for hiring teachers and that of famous schools, and the teaching team is relatively stable, and there has been no large-scale recruitment or urgent recruitment in five years. Polytechnic branches pursue simple teaching, and are more inclined to recruit young and middle-aged teachers with rich teaching experience. By the end of 2017, more than 40% of the teachers in the university had master's or postgraduate degrees, and about 85% of the teachers had intermediate or higher professional titles.

Many students say that the campus is too small, with an area of 9,000 square meters, 1.3 times the size of a standard football field. Students can only hold sports meetings in the 200-meter track and field field, and the number of basketball courts is only three. In 2015, the school renovated the school's appearance, and since then the polytechnic branch has a school motto, vending machines have also entered the campus, and although the classrooms have a new look, the construction quality is not good, and blackboards, doors, locks, and curtains are often damaged. In addition to the museums in the city, students also have the opportunity to "go down to the south of the Yangtze River" and visit the gardens of Suzhou. Polytechnic campuses are relatively rustic, student clubs are not abundant, and organizations oriented to cutting-edge elements such as hip-hop and cosplay may be restricted.

At least after 2016, all classes in the Polytechnic branch will be called experimental classes, and each class will be subdivided into Chinese, English, mathematics, and comprehensive experimental classes. If you need to be deployed, you may refer to the comprehensive quality assessment and entrance test results, but don't worry, the exam is not too difficult. At present, the Polytechnic branch also offers elective courses, which can be voluntarily signed up for by students in the first and second years of junior high school, and the content of the content is biased towards the direction of ancient literature, and there is no positive response from students.

The first year of the Polytechnic branch is relatively easy; In the second year of junior high school, the amount of homework and courses have increased, and the end of school will be postponed to 17:00; In the third year of junior high school, students may have make-up classes on weekends, and on the whole, the study will not be too heavy. In recent years, the school has upgraded the canteen, the desserts are more exquisite, there are fruits served every afternoon, and there are fewer meat dishes for the main meal. The school has a simple academic style, the teachers are more responsible, and the grades and students are better than the main department, but the quality of the school's high school is average, and most students will choose to apply for other schools in the recruitment stage. The tuition fee of the Polytechnic branch is 15,000 yuan/semester; The accommodation fee is 2,000 yuan/semester, and the school does not make accommodation mandatory.
