Has the retake rate hit a record high in recent years? Some of the media stats are pretty staggering. Most of these data are based on the original data from the big test center, which is calculated by the media itself. The highest estimate that has ever appeared is 22% (that is , one person in every five people retakes the test ). Most of the data on the high re-examination rate are calculated based on the "proportion of non-graduate students who refer to the test". However, there are several reasons for this calculation to overestimate the actual rate of retesting behavior: (1) Fewer births make the denominator smaller and smaller each year.
(2) The number of candidates for the exam is decreasing year by year, which reduces the number of candidates (denominator) for the exam. (3) Most of the repeaters rely on the test. (4) The definition of re-examination rate is loose: non-graduating photo retouching students may not be equivalent to re-examination candidates (generally speaking, candidates who have graduated from high school for more than three, four or more years are not typical re-examination behaviors). The sum of the above factors makes the denominator smaller and smaller, and the repeaters are concentrated in the numerator of the exam channel in the form of "non-graduate students". Re-examination behavior will indeed get the above amazing data.
Through the Ministry of Education's commissioned plan, we were able to count the data of the past years, connect the data of the two units, and identify the data of the same candidates who took different exams in the year, so as to reduce the lack of only counting the test. If a typical repeater is defined as "retake the exam within three years after graduating from high school",  Table 1 presents two calculation methods for the retake rate. One is the left half), and the other is the percentage of the candidates who have actually retaken the exam one, two or three years after graduation (the right half of Table 1).
