The country's cadre selection system has actually undergone multiple rounds of reforms. But the aim is one, to promote younger, better educated and more capable people to managerial positions in the party and government. And what needs to be mentioned is that a cadre may not necessarily needs to be a member of the Communist Party of China. China hopes to have a scientific and standardized system in cadre selecting. Several key principles are here.
First, selection and appointment should be based on merit, moral integrity and professional competence. And, during the selection process, openness, equality, competition, and the concept of "selection of the best" are emphasized. In the mean time, cadres must aspire to communism and has confidence in socialism with Chinese characteristics.
So, so much for requirements. What about the actual selection process? Well, "Democratic recommendation" is the first step. Candidates will be put up by way of voting and interviews. Then meticulous appraisal COMES NEXT before a decision is reached after collective discussion. A system of public notification will then follow, before the appointment is official. It is also worth mentioning that since the 18th National Congress of the CPC in 2012, the Party's central authority has made a series of rules about selection and appointment of cadres, with a particular focus on possible demotions if cadres are found irresponsible or incompetent in their post. This means it's no longer just a one-way street. You have to be good enough to be selected in the first place, and you must continue to deliver in your position.
