Deregistration is the removal of a student from classes by his or her School for a semester for failing to meet the requirements which the university makes a pre-condition of being allowed to register for courses. Deregistered students can earn no credit towards their degree in that semester.
Deregistration happens in the Ted Rogers School of Business Management when probationary students do not have their Plan of Study for a particular semester approved by the School. Since they have failed to comply with the University's requirement that probationary students "may not continue their program studies until a specific plan for studies has been authorized by their program School or Department and recorded with the Registrar", and since they have failed to have a probationary plan of studies (i.e. probationary contract) approved by their program department, the Ted Rogers School of Business Management has students' course enrolments and course intention requests cancelled for the term in question.
