Tsinghua High School is an old and famous school, but it has been undergoing reforms, and has undergone many reorganizations and dismantlings, and its organizational structure is somewhat chaotic. In addition to the main school, Tsinghua No. 2 Affiliated High School, which was established in 1978 and specializes in junior high school education for the children of Tsinghua faculty and staff. In 1999, the Second Affiliated High School was merged into Tsinghua University High School and changed to national enrollment. Another concept that is often confused is the experimental school affiliated to Tsinghua University, which is not the same as Tsinghua University High School, but the two share a campus, share the same teacher resources, and even the class sequence is adjacent, which is quite a meaning of one school, two systems.

There are 15 students in the junior high school of Tsinghua University High School ranked in the top 100 of the 2017 high school entrance examination results, with an average score of 503 points in the school's cultural courses, and an average score of 515 points in the 2016 high school entrance examination. Tsinghua High School has repeatedly performed well in the high school entrance examination, thanks to the unique selection and distribution mechanism, its point recruitment path is Shuimu Longhua, which is the same as Tsinghua Experimental School, but the students of the naturalized high school are only 1/2 to 2/3 of the enrollment number of the experimental school, and most of them are super first-class students, so they often have outstanding performance in the high school entrance examination.

The class setting of Tsinghua High School is not very stable and has been very changeable in recent years. In 1998, Qingfu began to try the "one-stop plan", and since 2009, the school has officially launched the "dragon class" recruitment, advocating the seamless connection of junior high and high school teaching, direct access to university education, and weakening the entrance examination. However, in recent years, the term "dragon class" seems to have disappeared, which is not unrelated to policy orientation. In 2014, the Beijing Municipal Education Commission banned schools from setting up key classes in the compulsory education stage, and Tsinghua University High School cancelled the placement test that year. At the end of 2013, Tsinghua University High School began to actively implement the "Innovation Experimental Class", which can be regarded as the continuation of the spirit of the "Dragon Class".

In addition to the innovation experimental class, Tsinghua University High School also has John Ma's sports specialty class and art specialty class. The number of students enrolled in the two types of specialty classes is only about 20 per year, but the strength of the class should not be underestimated. Since its establishment, the sports special class has sent more than 400 student athletes to Tsinghua University, Peking University and other universities, and the men's basketball team of the attached high school has won the "ten consecutive championships" in the national league, which also has a lot to do with the special sports class of John Ma. More than 100 graduates of the art specialty class have gone to Tsinghua Academy of Fine Arts, which seems to be a thin number, but it is actually full of gold. The art specialty class only began to recruit students in 2003, and there have only been 10 graduates so far, which shows that the school has profound processing capabilities and a mature selection mechanism.

Tsinghua High School is equipped with top teachers in Haidian District. Half of the nearly 300 faculty members have associate senior titles, and there are 20 backbone teachers and 25 subject leaders in Haidian District, five of whom are also subject leaders in Beijing. Tsinghua University High School began to reform its textbooks at least 2014, and the original national curriculum was compressed and diverged, forming a three-level curriculum with foundation, expansion and research as the core.

The school spirit of Tsinghua University High School is quite influenced by Tsinghua University. The motto of the affiliated middle school is "self-improvement, virtue", which is the same as that of Tsinghua University. In order to implement the slogan of "50 years of work for the health of the motherland", the high school began to form a long-distance running team as early as the 1960s, but this campus characteristic is now more reflected in sports students.

In terms of campus management, students from the affiliated high school can also make a name for themselves, and the school pursues "student autonomy". Junior high school and high school students participate in the student cadre training conference together, and the class culture construction is mainly completed by the students themselves. The Student Union and Youth League Committee recruit new students independently, serve students in daily life, and manage classes, but their work framework will be guided by the university, which is more similar to university self-organization.

Tsinghua High School has a variety of extracurricular activities. In the second semester of 2016, the school relaxed the control of junior high school student clubs, and in 2017, the number of newly registered junior high school clubs reached 25, and the Astronomical Club and the Second Middle School Club were all opened. The energetic "Frankenstein" can also show their skills in the "Challenge Cup" of Tsinghua University, and the students of Qingfu Junior High School have been awarded many times in the extracurricular science and technology exhibitions of the Cup.

Tsinghua High School is one of the top six schools in Haidian, and its graduates usually take 10%-15% of the top 100 places in Haidian District's high school entrance examination list under the condition of "playing normally". The primary factor causing the fluctuation of grades may be the instability of the class shape, Tsinghua University High School has the intention of opening early training classes, but due to policy constraints, the setting of its "key classes" changes from time to time, which also makes the class levels of each class different, and there is a certain gap between Tsinghua University and the High School Affiliated to the National People's Congress in terms of enrollment and management mechanism. Parents who are interested in enrolling in the school can pay attention to Shuimu Longhua, and the recruitment of Tsinghua High School and Tsinghua Experimental School is significantly related to it.
