A scientific educational evaluation system is directly related to the connotative development of higher education and the realization of the grand goals of educational evaluation reform in the new era. In October 2020, the "Overall Plan for Deepening the Reform of Education Evaluation in the New Era" issued by the Central Committee of the Communist Party of China and the State Council put forward new arrangements and new requirements for the reform of education evaluation in my country, emphasizing the reversal of the unscientific orientation of education evaluation, and resolutely overcoming the need for grades and promotion. It also proposed that by 2035, an education evaluation system that is full of the characteristics of the times, highlights Chinese characteristics, and reflects the world level will be basically formed. However, due to various internal and external reasons in education, the evaluation of higher education has problems such as only papers, projects, awards, professional titles, and hats to different degrees, which seriously restricts the healthy and orderly development of my country's higher education. The "14th Five-Year Plan" period is an important stage for my country to achieve high-quality education development, and it is also a critical period for implementing the reform measures of education evaluation in the new era. It is imperative to build a higher education evaluation system in the new era. Starting from the political, educating and social nature of education, around the fundamental issue of "cultivating people for whom, who to train, and how to train people", an organic structure consisting of three dimensions of political standards, business standards and efficiency standards is constructed. The "three-in-one" higher education evaluation system is formed. The dimension of political standards is the key to the "three-in-one" higher education evaluation system, which determines the direction of education. It mainly includes four elements: the direction of school running, the ideological and political construction of courses, the quality of personnel training, and the construction of teaching staff. The dimension of business standards is the core of the "three-in-one" higher education evaluation system, which reflects the performance of the functions of higher education institutions, mainly including three elements: education and teaching, scientific research and social services. The benefit standard dimension is the foundation of the "three-in-one" higher education evaluation system, which reflects the social service effectiveness of colleges and universities, and mainly includes three elements: academic influence, economic influence and social influence. The "three-in-one" higher education evaluation system is an integration of concepts composed of many related elements. Each element forms an organic whole with specific functions, showing the characteristics of integrity, hierarchy and openness. The construction of the "three-in-one" higher education evaluation system will help to overcome the "five-only" stubborn malaise and lead institutions of higher learning to return to their essence; it will help to implement the fundamental task of morality and cultivating people, and guide the direction of colleges and universities; it will help to comprehensively Improve the quality of education and promote the connotative development of higher education.
