If they do not have satisfactory level and do not meet entry level, do not let them take the course. If they donít have a first aid and CPR certificate, you can schedule a course with the examiner before or after the ITC. If they donít have teaching experience, tell them to pass an assistant training (this can also be scheduled with the examiner before the ITC if you donít have Level 2 instructors working near you). As for the boat license, check if one is needed in your country. If yes, make sure they have a license.
