The issue of teaching quality in colleges and universities has received widespread attention, and teaching reform using information technology has become a way to improve the quality of university teaching. In this paper, an improvement method is proposed that combines the CBE competency education assessment model and improved C-ADDIE to create a teaching reform model for software engineering courses. After quantitatively assessing students’ professional competence using the IAHP-BP model, students with different competencies are divided by clustering and grouping to analyze the professional competence of software engineering students in terms of the whole and specialty. The professional competence score of the reformed students is 82.103 for the A class students, and the worse performing B class students, the professional competence score is only 72.639, and the gap between the two classes is close to 10 points. After the education of competency assessment with the model proposed in this paper, the student’s professional performance was improved with 11 points in the high score band, and the number of low score bands was gradually reduced. The model developed by the research is a valuable resource for computer software engineering students.
