TS EN ISO 11121

TS EN ISO 11121 addresses the minimum programme content for training organizations offering introductory scuba experiences in recreational diving. It focuses on how these trial-format diving programmes should be structured so that first-time participants receive a controlled, clearly framed introduction to scuba diving.

What introductory scuba programmes are designed to do

Scuba refers to underwater breathing using self-contained equipment, while introductory programmes are short, entry-level experiences rather than full certification courses. In general technical terms, these programmes are meant to familiarise participants with the diving environment, basic equipment, communication cues, and supervised in-water activity in a way that is understandable and manageable for beginners.

The standard’s minimum-content focus

The document’s specific concern is the minimum content that training organizations should build into such programmes. That means the standard is about programme structure and essential instructional coverage, not about turning the experience into a complete diver training syllabus. In the broader diving-services context, introductory sessions commonly rely on gradual orientation, equipment awareness, supervision, and participant confidence-building; this standard confines itself to the minimum programme content needed for that introductory setting.

As a result, TS EN ISO 11121 serves as a reference for the introductory side of recreational scuba services. It helps distinguish a first-contact diving experience from formal certification training and supports a more consistent way of delivering beginner-focused programmes.
