“'The Future of Diving' caught my attention when I found the ITDA website in 2000. I started with the Singapore Underwater Federation (CMAS) in the 1980s, then SSI, and later PADI where I worked my way to Master Instructor and Course Director. Since joining ITDA in 2003, I have not looked back. ITDA-IHMP is the world's only agency offering occupational diving — providing real-world skills for divers to pursue a career pathway in occupational diving.”

What Divers & Instructors Say
Hear from members who have experienced the ITDA-IHMP difference.

“As a PADI Instructor I struggled with the commercialization of diving rather than a stronger focus on the science and safety of diving. As I explored the ITDA programs, I was immediately impressed with the balance of depth and quality of the materials while also being approachable and flexible. I would recommend the ITDA programs to any level of diver who is serious about the sport.”

“I'm a diving instructor of 20 years with a national federation and I took an ITDA Specialist Technical Course and found it to be fantastic... I am now just upgrading to ITDA instructor trainer... Great fun, great instructor standards and great service from ITDA HQ. Since I joined the ITDA Family I've never looked back.”

“We were CMAS-certified divers for years before crossing over to ITDA. The transition was seamless and the Specialist Pro pathway opened up technical diving opportunities we never had access to before. The support from ITDA HQ in Singapore and Malaysia has been outstanding.”

“ITDA is able to cover other domains which other agencies are unable to do so. What I like about ITDA-IHMP is the technical and medical domains as well as the occupational pathways. The future looks promising and it will perform and grow from strength to strength. I certify across Scuba, Technical, and Hyperbaric/Medical programs, and I hope ITDA will kickstart a new swimming programme.”
