Written reexaminations may be given to students who receive failing grades, subject to certain limitations. Reexaminations are rarely given to students who received a course grade of less than 50%. No reexaminations are given, regardless of the grade, if the course which has been failed is not required training for the individual unless a request is received from the student's management. Only one reexamination will be given to a student for any given course. Any student who fails a reexamination must repeat the course to satisfy the training requirement.Reexaminations must be requested by the student's management to the cognizant ADTD Chief. A prepared reexamination will then be mailed with a cover letter to the student's immediate supervisor. This letter will indicate how the reexamination should be administered. The completed reexamination must be returned to the TTC immediately upon completion.
