Scuba Diving International (SDI) is one of the most recognized scuba certification agencies worldwide, offering a structured certification path that guides aspiring divers from beginners to advanced professionals. The SDI certification levels are designed to build both skill and confidence, ensuring divers have the knowledge and practical experience to enjoy safe diving adventures. Whether you’re just starting out or looking to pursue a professional career in diving, understanding the SDI certification path is essential for planning your progression.

SDI’s certifications focus not only on skill acquisition but also on environmental awareness, dive planning, and emergency preparedness. The program emphasizes modern training methodologies that include performance-based evaluations and use of dive computers, reflecting current industry standards.

This article breaks down the SDI certification levels, exam codes, certification requirements, and the overall certification path for aspiring divers. In this first part, we will cover the foundational SDI certifications that introduce new divers to the underwater world.

SDI Open Water Scuba Diver Certification (Exam Code: OW-101)

Overview

The SDI Open Water Scuba Diver certification is the entry-level course that allows individuals to dive independently with a buddy to a maximum depth of 18 meters (60 feet). This certification is internationally recognized and is the foundation for all advanced certifications within SDI.

Certification Path Placement

The Open Water Diver certification is the first step in the SDI certification path. Completing this course qualifies a diver to pursue advanced recreational certifications such as Advanced Open Water, Rescue Diver, and specialty courses, or professional training like Divemaster.

Course Structure and Content

The Open Water course combines academic knowledge, confined water skills, and open water dives. The curriculum covers fundamental diving principles, including:

• Diving equipment assembly and maintenance
  
  

• Dive planning and execution
  
  

• Basic dive physics and physiology
  
  

• Safety procedures and emergency protocols
  
  

• Underwater communication and navigation
  
  

The course involves knowledge development sessions, typically conducted through self-study materials or classroom instruction, followed by confined water training where students practice skills in a pool or controlled environment.

Exam Requirements and Certification

The SDI Open Water exam evaluates understanding of theory topics. It typically consists of multiple-choice questions covering diving physics, equipment, safety, and procedures. Candidates must pass the exam with a minimum score of 80%. The practical portion requires successful completion of at least four open water dives demonstrating essential skills such as buoyancy control, mask clearing, regulator recovery, and emergency ascent techniques.

Upon passing both theoretical and practical components, candidates receive the SDI Open Water Scuba Diver certification card.

Certification Validity and Renewal

The SDI Open Water certification does not expire, but divers are encouraged to refresh their skills if inactive for an extended period. Refresher courses are available for those who have not dived in over a year to ensure safety and confidence before resuming diving activities.

SDI Advanced Open Water Diver Certification (Exam Code: AOW-201)

Overview

The Advanced Open Water Diver certification builds upon the skills and knowledge acquired in the Open Water course, expanding a diver’s abilities and underwater experience. This certification enables divers to increase their maximum depth limit to 30 meters (100 feet) and introduces specialized diving activities.

Certification Path Placement

This is the natural next step after Open Water Diver certification in the SDI certification path. It is essential for divers aiming to expand their skills or prepare for more challenging courses such as Rescue Diver or Divemaster.

Course Structure and Content

The Advanced Open Water course includes five adventure dives, each focusing on different specialties to enhance diving competence. Typical dives include:

• Deep Diver: Training to dive safely to 30 meters, understanding physiological effects and hazards of deep diving.
  
  

• Navigation Diver: Skills to use compass and natural underwater navigation techniques.
  
  

• Night Diver (optional): Techniques for diving in low visibility or darkness.
  
  

• Search and Recovery Diver (optional): Procedures for locating and recovering lost objects underwater.
  
  

• Wreck Diver (optional): Safe practices for exploring wrecks without penetration.
  
  

Students choose adventure dives based on interest, with some options tailored to local diving conditions.

Exam Requirements and Certification

The Advanced Open Water certification exam tests knowledge related to the specialty dives undertaken during training. Candidates complete written or oral exams for each specialty dive with a passing grade of 80% or higher. The practical component requires successful completion of all five adventure dives under instructor supervision.

Upon successful completion, divers receive the SDI Advanced Open Water Diver certification card, permitting dives up to 30 meters with a buddy.
