The SSI Classified Diving program has been created to enable persons with disabilities who might not be able to earn full certifications the ability to dive and get certified with different safety parameters. Learn to work with disabled divers.
The dive agency equivalent certifications chart below is useful when enrolling on a new scuba diving course with Ocean Tribe. If you have been certified through SSI, NAUI or CMAS, then you will need to know which PADI course your diving certification allows you to enrol on. While there are other diver training organizations we have listed the ones that meet the ISO safety standards and are recognized as the largest.
Ratings are shown as to what the direct equivalent is and therefore you can enter the next course below on the scale. So for example a SSI Open Water Diver is equivalent to an PADI Open Water Diver and therefore able to enroll on the PADI Advanced Open Water Diver program.
