If you are readmitted within one year of leaving the university, you will be subject to the academic policies and requirements that were in effect at the time of your original matriculation date.
You matriculate by registering for and starting an academic semester as a degree-seeking student. You do not need to declare a major in order to matriculate. If you begin taking classes in the summer, you will be considered as matriculating in the fall semester.
After one year, Enrollment Management, after advisement with the impacted academic offices, may determine whether current policies and requirements (in whole or part) will be applied.
