Your certifications transfer across agencies — here’s how.

Many divers wonder how scuba agencies compare — or whether certifications from PADI, SSI, NAUI, SDI, or PSS are interchangeable. The good news is that all major recreational scuba agencies follow the same international ISO standards. That means your training transfers cleanly, and you can continue your education with OCD Divers without repeating courses.

The chart below shows how the most common scuba certifications align across agencies, helping you understand your next step whether you trained with PADI, NAUI, SSI, or PSS.
