Divemaster Training on Koh Tao

Divemaster Training on Koh Tao (2025 Guide)

Becoming a Divemaster is the first step into the professional world of scuba diving. On Koh Tao, one of the busiest training hubs in the world, you’ll find courses with the three major certifying agencies: PADI, SSI, and RAID. Each follows international standards and prepares you to supervise dives, assist instructors, and grow into a dive professional — but they differ slightly in philosophy, flexibility, and fees.

Agency options on Koh Tao

  • PADI (Professional Association of Diving Instructors) — The largest and most globally recognized agency (est. 1960s). Their Divemaster program is highly standardized and widely transferable — ideal if you plan to work internationally.
  • SSI (Scuba Schools International) — Established in the 1970s by diving professionals. Long viewed as the more flexible “digital-first” alternative, SSI has grown strongly in Asia and Europe, with competitive material fees and robust e-learning.
  • RAID (Rebreather Association of International Divers) — Originally tech/rebreather-oriented, RAID has expanded rapidly over the last decade as a mainstream recreational agency across SE Asia, with modern e-learning and strong environmental emphasis.
