At present, the types of cadre training can be roughly divided into two categories: the first category is the main class and special seminar training organized by the organization department relying on training institutions such as party schools (administrative colleges), cadre colleges and universities. For example, Party schools have middle-aged classes, on-the-job classes and special seminars. The second category is the cadre training courses organized by each unit itself. Generally, it is held in cooperation with party schools, cadre colleges and on-the-job training colleges in colleges and universities. The training time will not be too long, and most of them are short-term training courses. Judging from the current situation, the middle-aged class, that is, the young cadre class mentioned in the title, has the highest gold content in the cadre training class. In the past, the training places of middle-aged and young classes were allocated by the organization department to lower-level organizations and party and government departments at the same level, and all localities and units put forward the training list on the basis of grade and age requirements. At present, many local organizations have mastered the list of young and middle-aged cadres who meet the age requirements in advance, and then arranged for these cadres to participate in the training of young and middle-aged classes in batches in a planned way. Among all the training courses, only the middle-aged class organized by party schools (administrative colleges) at all levels has rigid requirements on the age of students, and the training time of this class is also the longest, reaching 4 months, which is longer than other training courses. This also means that those who can participate in the training of middle-aged classes are relatively young cadres with development potential. After filling in the shortcomings of training experience, these cadres have entered the field of vision of the party group (party Committee) and organization department of the unit, and are more likely to be promoted and appointed. Facts have also proved that cadres who have participated in middle-aged class training are far more likely to be promoted than cadres who have participated in other classes. Therefore, from this perspective, it is definitely a good thing to be able to participate in the training of middle-aged classes. Of course, if you attend the training of middle-aged classes, you can be promoted immediately. Although some cadres have been promoted in the training, they are a minority after all. Most of the cadres who have participated in the training of middle-aged classes only mean that they have one of the basic conditions for promotion and appointment, and they belong to cadres who are optimistic about the organization and have development potential. In fact, in the process of selecting and appointing cadres, the requirements for training experience and training time are not very strict, and it is not a matter of "one-vote veto", and there is no need for approval procedures for promotion. Especially in recent years, affected by the epidemic, the opportunities for cadres to participate in training are much less than before, and many cadres who fail to meet the training requirements are promoted as usual.
