It is recommended to all SDI, TDI, and ERDI instructors that they verify new students can demonstrate skills required in previous courses.  As a result, if you are enrolling in an SDI, TDI, or ERDI course and coming from another organization you may be required to do a check-out dive with your instructor to verify that your skills and knowledgebase line up appropriately for the course, prior to commencement of training.  We also recommend divers take a refresher course after a period of not diving, this period, while not a hard and fast rule, is about a year. This simply means that even though you hold a certification it is always a good idea to go on a dive with a professional and refresh your knowledge and skills.
