ITDA offers a full range of scuba certifications — from Experience Programs and day courses to Scuba Open Water Diver, the first international certification level that allows unsupervised diving (ISO 24801-2 / EN 14153-2). The Open Water program requires a minimum of 6 open water dives and can be completed in 2–3 days. From there, divers can progress to Rescue Diver, Advanced Open Water, and Specialist ratings.
