TS EN ISO 24801-1

TS EN ISO 24801-1 is the standard focused on entry-level training for recreational scuba divers and the profile known as “Level 1 – supervised diver.” It brings together training and supervised diving within recreational diving services, providing a common framework for building basic competence in controlled conditions.

What the supervised diver level means technically

In general technical terms, scuba diving involves breathing equipment and exposure to pressure changes, so training must combine skills practice, environmental awareness, and supervision. The term “supervised diver” indicates a diver whose experience is still limited and whose dives are intended to take place under appropriate oversight, unlike fully independent diving. That distinction matters because it defines the level at which core abilities are introduced and managed, from equipment handling to basic underwater adaptation.

The framework covered by the standard

• Training of recreational scuba divers within recreational diving services
• Supervised diving practice
• Level 1 - supervised diver profile
• Rules that connect training with supervision

As a reference standard, it can be used to structure training and supervised-dive arrangements, but no specific training hours, depth limits, mandatory test steps, or equipment inventories should be assumed here beyond what the standard itself states. Its practical value is that it helps different providers describe the same foundational level with a consistent technical vocabulary and expectation set.
