First degree collaborative training usually refers to students' first degree at undergraduate level, such as bachelor's degree or bachelor's degree honor class. Collaborative training refers to the cooperation of many universities to provide students with a broader, more comprehensive and deeper learning experience. The meaning of first degree collaborative training is the degree that students get when they get their first degree at the undergraduate level.

Undergraduate education jointly run by higher vocational colleges refers to the undergraduate education jointly carried out by higher vocational colleges and ordinary undergraduate colleges. In this mode, students can complete the first two years of professional basic courses in higher vocational colleges, then transfer to ordinary undergraduate colleges for further study, and finally get a bachelor's degree. This move aims to provide more opportunities and choices for more vocational and technical talents who are interested in receiving higher education, and promote the integration and development of vocational education and general education.

The first degree is the general full-time education of national education series, which is the highest degree in full-time colleges and universities. It does not include full-time self-study, adult college entrance examination (correspondence, amateur), TV University, online education (distance education) and other forms of on-the-job education.

The Ministry of Education has made it clear that the first degree is a general full-time degree. In fact, after the expansion of Chinese mainland University in 1999, there was no such thing as the first degree. In practice, the highest academic qualification of general full-time education is still called the student's first academic qualification before enrollment expansion.

The official answer from the Policy and Regulation Department of the Ministry of Education is that the relationship between the first degree and the second degree is two types of degrees at the same level. In the past, the superiors of ordinary junior high schools, ordinary senior high schools and ordinary colleges and universities were the first education bureaus of all provinces and cities, and the academic qualifications issued at graduation were called the first academic qualifications; Other forms of continuing education, such as adult high schools, higher education self-study exams, adult college entrance examinations, etc., are under the responsibility of the second education bureaus of provinces and cities, and the academic qualifications awarded are called second academic qualifications.
