The brand of OSAC Vocational Qualification Examination and Certification Center (OSAC) is promoted by vocational skill appraisal institutions approved by the government, mainly engaged in vocational qualification training, vocational qualification appraisal, vocational ability evaluation and other services. The center has established good cooperative relations with domestic vocational education departments, universities, enterprises, society and other relevant institutions, absorbed the experience of international vocational qualification education, and combined with the certification standards of China's vocational appraisal departments, it has been well applied to China's vocational qualification training and education, and achieved good results. After years of development, it has formed a comprehensive research institute with a certain scale and various businesses in vocational qualification research, vocational standards and national industry standards training, vocational skill appraisal, technical exchange, consulting services, international exchange and cooperation, and established friendly and cooperative relations with many international, regional or national vocational education and certification groups. It is on the premise that the state attaches importance to the construction of professional standard system of vocational qualification departments and gives full play to the role of trade associations that the center cooperates with government departments to improve the scientific nature of vocational education and the gold content of vocational qualification certificates. 1. With the deepening of economic system reform, the types of enterprises are diversified, including foreign-funded enterprises, joint ventures, private enterprises, family enterprises and state-owned enterprises. The employment mode of students has also changed, and the understanding and requirements of various enterprises for vocational qualification certificates are also different. Especially with the reform and development of China's economic system and the cancellation of government departments such as economic commission and foreign trade and economic cooperation, trade associations will become the main body. The state should vigorously support trade associations and give full play to their roles in setting professional standards, strictly enforcing employment access, and popularizing the vocational qualification certificate system. Second, the center pays attention to the connotation of vocational qualification certificate and strengthens the authority of the certificate. The connotation of vocational qualification certificate itself should include six aspects, which can contribute to the development of vocational education. (1) practicality. Vocational education should pay attention to the post requirements and changes of enterprises, strictly formulate the assessment standards of vocational qualification certificates suitable for posts, and link certificates with posts to realize "zero job transfer". (2) Sociality. Vocational qualification certificates should adapt to the changes of social and economic development, be generally recognized by the society, have a high social status and social recognition, and enhance the attractiveness of certificates to society, enterprises and students. (3) complexity. In the process of cultivating knowledge, ability and quality, vocational education should emphasize its breadth and width, broaden students' knowledge and adaptability, enable students to have the spiral ability of self-adjustment, self-improvement and self-learning, and enable students to achieve all-round development and have the foundation of sustainable development. (4) interchangeability. The exchange of vocational qualification certificates with courses and academic certificates makes vocational qualification certificates have good flexibility and adaptability. This exchange not only increases the adaptability of higher vocational qualification certificate, but also reduces the promotion cost of qualification certificate. (5) openness. Vocational education qualification certificates can be opened to the society, and schools provide training and research opportunities and platforms for all kinds of social personnel to achieve "win-win" and improve the social status of vocational education qualification certificates. (6) internationalization. According to China's national conditions and practice, and according to the needs of internationalization, we should formulate standards and requirements to adapt to the cultivation of students' internationalization ability and become an international vocational qualification certification. Third, we are committed to reforming the vocational education model and providing a good certification platform. China is in a period of rapid economic development, and the original professional content will usually undergo new changes. At the same time, many new occupations and positions will continue to emerge. Many workers are currently facing the structural adjustment of their occupations and posts, and some workers need to switch to new occupations and posts. This structural vocational adjustment needs the socialization of vocational education to solve it. In order to meet this demand, higher vocational colleges should carry out in-depth reform of educational connotation, so that education and employment can be closely combined to better meet the needs of the labor market. This can be done from the following aspects: (1) Setting up a curriculum system with vocational qualification certification as the core. That is to say, a professional curriculum system is set up with the national qualification examination subjects as the center, and each vocational qualification certification has a series of examination courses. (2) To carry out teaching activities for the purpose of professional qualification certification. In order for students to obtain qualification certification in school, it is necessary to strengthen the education of "double certificates" and carry out teaching activities for this purpose. It can be taught by means of principle teaching, skill training and certification examination, which provides a good platform for students' research. (3) Evaluate the teaching effect with professional qualification certification as the standard. Higher vocational education should be linked with vocational qualification certification, and the traditional assessment standards and methods should be changed, especially the assessment of professional courses. At this stage, we can consider using two standards to assess the teaching effect: one is the traditional assessment standard, which can be used in the assessment of public courses and basic courses; The other is the examination of professional courses based on professional qualification certification, such as construction engineering technology, so that the teaching of professional courses can be assessed based on the registration rate and pass rate of professional qualification certification of builders, quality inspectors and budgeters.
