The gaobao line of Guangzhou senior high school entrance examination is delineated by the municipal admissions office after the results of senior high school entrance examination are announced and before admission.

The Gaobao line, that is, the high-scoring priority investment line, was delineated by the municipal recruitment office after the results of the senior high school entrance examination were announced and before the admission. The original intention of setting up the Gaobao line is to protect high-scoring candidates from being admitted to the school and avoid the phenomenon of high scores, low records and even unsuccessful elections.

Regarding the Gaobao line and the advance approval control line, in fact, referring to the filing rules of the college entrance examination or the civil service examination, we can draw several ways: specifying the score (for example, 700 regardless of the difficulty of the topic), the top proportion of the total number of candidates (for example, marking one, two and three books in the college entrance examination), and setting the specific number (for example, recruiting civil servants in some cities).

According to the relevant school enrollment 1 to 1.05 (or 1 to 1), and so on. If any of the above rules are written in black and white in the Administrative Measures, then when their scores (especially the city's admission order) come out, then Gao' an whole line or early control line need not be announced, and candidates naturally know whether they are online or not.

The functions of high-safety lines are as follows:

1. Simply put, Gao 'an can give high-scoring candidates who have passed the high-scoring protection line an advantage in the senior high school entrance examination and avoid falling out of the list. According to the rules of giving priority to volunteers and scores in the senior high school entrance examination in Guangzhou, students who have passed the Gaobao line are first admitted according to their own wishes. After all these students are admitted, if the school does not accept all of them, they will be admitted below the Gaobao line until the enrollment plan is completed.

2. In other words, as long as the candidates' scores in the senior high school entrance examination are above the whole line of Gao 'an, the admission scores of the schools they apply for are below the whole line of Gao 'an, and schools can be admitted no matter how many times they volunteer to fill in. The high score guarantees the children who are in the forefront of the city and have a particularly high score. In order to prevent the school from over-publicizing after the scores were reported, it was banned by the Education Bureau.

3. In essence, it plays a protective role for high-level students and prevents excessive publicity for children. The setting ratio of priority filing line is about 30% to 40% of the number of online approval in advance. The setting of priority filing line can effectively protect students with relatively high scores in this batch and avoid high scores and low records as much as possible.
