PADI Scuba Diving Certification and Educational Materials

PADI, which stands for the Professional Association of Diving Instructors, is the world's leading scuba diving training organization. Founded in 1966 by John Cronin and Ralph Erickson, the brand was established to break down the barriers to entry for scuba diving by creating a modular, safe, and accessible training system. Today, it operates globally, providing everything from beginner e-learning courses to professional-level instructor certifications.

While the brand is headquartered in California, its operations are decentralized through various regional headquarters around the world. The company has moved through several ownership phases, and is currently owned by a private investment group. Its business model relies on a vast network of franchised dive centers and resorts that deliver the physical training, while the PADI corporate entity manages the standardized curriculum, digital materials, and certification database. It remains the most widely recognized dive certification brand internationally.
