We regularly receive questions about IAHD, our courses, and our teaching system. To avoid keeping you waiting too long, we've compiled the most frequently asked questions and their answers.
If you have more questions, you can always contact us.
Almost anyone with a physical or mental disability can take an IAHD course.
Of course, there are specific prerequisites for each course. There are also special programs for companions and supervisors.
Because your free time is entirely yours. With the IAHD system, you don't have to spend long hours in a classroom.
You study when and where you want, so you can participate directly in the practical sessions... that's what the course is for, right?
All IAHD courses are focused on learner achievement.
Therefore, there are no set minimum or maximum course durations. All theoretical and practical learning objectives are clearly defined.
Consequently, the length of an IAHD course depends on the time a learner needs to achieve each learning objective.
IAHD courses comply with the guidelines established by the latest ISO and CEN standards. IAHD courses are internationally recognized.
IAHD courses are slightly more expensive than standard scuba diving courses.
This is due to the extra equipment and time required to train a diver with a physical or mental disability.
Many countries offer subsidies for sports activities for people with physical or mental disabilities. Your IAHD Instructor can tell you more about the subsidies available in your area.
Very little.
All academic materials are provided before the course begins. All the equipment needed for the practical sessions is also provided; the only additional items you need are swimsuits and a towel.
Yes, to participate in an IAHD course you must be able to confirm the following:
- Yes, I want to learn to dive;
- Yes, my doctor has cleared me to dive;
- Yes, my instructor wants to train me.
Your IAHD Instructor will give you a medical examination form that must be signed by your doctor.
Your scuba certification is valid for life! However, regular diving is recommended to maintain your skills and knowledge. Try to avoid long periods without diving (6 months or more).
If it has been a while since your last dive, it is advisable to take a refresher course with an IAHD instructor.
