Legal analysis: the state allows education by stages. The so-called phased education is a payment model in which some schools and institutions with training qualifications pay tuition fees for students by stages. This model can reduce the barriers to students' enrollment to a certain extent, thus directly improving the enrollment rate, which can be provided by the school itself or by a third-party service platform. Education staging is also a kind of consumer finance. The education and training staging platform based on Baidu spending money and Squirrel Treasure helps students lower the entrance threshold and help schools and institutions improve the enrollment rate and the number of students. Among them, "low interest rate, easy application, no mortgage, fast approval and remote credit" have become the "five sharp tools" for the rapid popularization of education by stages.

Squirrel Baokai released a new model, which ensured the characteristics of low threshold and fast approval on the basis of upgrading the risk control system, and was deeply satisfied and trusted by business organizations and students. The development of education credit provides more learning opportunities for students and broadens the market scale for training institutions.

The appearance of phased products can not only meet the educational needs of users, but also reduce the impact on their quality of life.
