Which Certification Agency: PADI vs SSI vs NAUI
Summary
WeGoDive's partner schools on Koh Tao primarily offer PADI and SSI certifications. Both agencies are globally recognized and equally valid; your choice depends on school availability, instructor preference, and course structure.
Details
- PADI (Professional Association of Diving Instructors) is the largest agency worldwide with the widest recognition
- SSI (Scuba Schools International) is equally legitimate and growing, with flexible training methods some divers prefer
- NAUI certifications are less common on Koh Tao but available through select operators
- All three certifications are honored at dive shops globally—agency choice rarely affects future diving opportunities
- Pricing is similar across agencies: Open Water ~$350-450 USD, Advanced OW ~$280-350 USD
- When booking via WeGoDive, filter schools by your preferred agency or ask about instructor qualifications
- Consider the instructor's teaching style and school reputation more than the certification brand
