The invention relates to a failing credit prediction method, system and device for students in schools and a storage medium. The method comprises the following steps: obtaining student basic information, student scores, student all-purpose card data, library entry data, borrowing data and Internet surfing data; generating characteristic factor data according to the student basic information, the student scores, the student one-card data, the library entry data, the borrowing data and the internet surfing data; selecting a regression task model, and training by utilizing the regression task model and the characteristic factor data to obtain a failing credit prediction model; and re-collecting the characteristic factor data of the students, and obtaining failing credits of the students by utilizing the characteristic factor data and the failing credit prediction model. According to the failing credit prediction method for students in schools, accuracy of failing credit prediction is improved.
