How do youth league members play the "life trilogy" of pursuing political progress? In Hai'an City, Jiangsu Province, an institutionalized mechanism has been formed. Strictly control the plan, and strive to solve the problem of "how much is appropriate". On the basis of extensive and in-depth research, the Hai'an Municipal Party Committee of the Communist Youth League of Hai'an and the Organization Department of the Municipal Party Committee formulated and issued the Implementation Opinions on Further Standardizing the Work of Promoting and Joining the Communist Youth League of Hai'an, which clearly required the township and municipal league organizations to determine the annual "promotion" work plan according to the annual party member development indicators of the party organizations at the same level. Grass-root implementation is practical. Under the guidance of the Party's organizational department, all grassroots league organizations, in accordance with the principle of "recommend one for each mature one" and in accordance with the requirements of the party member development plan and the proportion of "recommend one", will jointly study and determine the specific plan indicators by field and industry classification. In the specific implementation, we should pay attention to the application of the results of the work of "benchmarking and grading", "double statement and double evaluation", etc. of the grassroots league organizations. The plan for the promotion of the five-star league organizations should be raised by 10%, and the plan for the promotion of the backward league organizations should be reduced by no less than 20%, reflecting incentives and constraints. The Hai'an Municipal Committee of the Communist Youth League conscientiously implemented the requirements of the guidelines for evaluating the progressiveness of League members and the guidelines for the incentive mechanism of the Communist Youth League issued by the Central Committee of the Communist Youth League, and formulated and issued the Evaluation System for the progressiveness of League members in Hai'an City based on the reality of young League members in different fields in Hai'an, Set up 12 specific indicators in four major aspects of League members' political learning, work performance, social contribution and moral integrity, and define specific rules for scoring and deduction, so as to achieve seamless connection between the evaluation of League members' progressiveness and "excellence promotion" points. In view of the actual performance of youth members who are willing to join the Party, explore and implement the "three ones" evaluation mechanism: "one person, one file", record the whole process of training and education, and make it well documented; "One point for each quarter", the League branch verifies and preliminarily evaluates the registered and declared points of the League members every quarter, and the League members' meeting of the League branch informs the preliminary evaluation of the branch committee, and assigns points according to the actual work performance; "One review every year", the Youth League Branch will carry out a democratic review every year, and the results of the review will be publicized, and the candidates for the "selection" target will be determined according to the comprehensive score and review results. Strictly control the procedure and focus on solving the problem of "how to promote the standardization". In Hai'an, the grass-roots Youth League organizes and implements the "three-step" procedure to ensure that the "optimization" process is standardized, strict, fair and fair. ——Choose the best. Promote grassroots league organizations to establish a "trinity" mechanism of recommendation of outstanding young talents, including organization excavation, individual recommendation, and recommendation of party members and the masses, screen young league members who meet the conditions of "recommendation" one by one, and establish a "recommendation" object pool. ——Specification recommendation. Take the Youth League branch as the unit, hold the "optimization" meeting in a standardized manner, and determine the candidates for the "optimization" object through a series of steps such as the democratic evaluation of the Youth League members, the research of the Youth League branch committee, and the publicity of the results. ——Strict review. The superior group organizes the review of the recommendation opinions of the group branch, inspects the recommended objects, compares the qualification conditions one by one, summarizes the conditions of qualified "excellent" objects and the investigation materials, and recommends them to the party branch, and makes full communication. Strictly control the training
