CMAS Overview

CMAS Logo CMAS (Confédération Mondiale des Activités Subaquatiques) is the umbrella organisation to which many of the other Diving Agencies subscribe to, especially club based organisation such as BSAC, VDST (German Divers Club) and many others use the same rating structure.

 

Via the CMAS structure most European diving agencies will align themselves to the set European Standards - the standards are defined under EN-14153-1 (Supervised Diver), EN-14153-2 (Autonomous Diver) und EN-14153-3 (Dive Leader). EN-14413-1 and EN-14413-2 are standards set for instructors, in addition there are special standards for Nitrox.

 

An overview of EN-14153 (Divers) standards are shown below. As you can see the standards are very generic, for more specific training programs click on the buttons below.

Supervised Diver
Minimize
EN 14153-1/ISO 24801-1 specifies the competencies that a scuba diver has to have achieved in order for a service provider to award the scuba diver certification indicating that he has met or exceeded scuba diver level 1 – “Supervised diver” and specifies assessment of these competencies.

 

A scuba diver at level 1 – "Supervised Diver" shall be trained to have sufficient knowledge, skill and experience to dive in open water under the direct supervision of a dive leader.

 

Scuba divers at level 1 – "Supervised Diver" are qualified to dive within the following parameters accompanied by a dive leader:

  • Dive to a recommended maximum depth of 12 m under the direct supervision of a dive leader
  • Dive in groups of up to four level 1 scuba divers per dive leader provided the dive leader is capable of establishing physical contact with all level 1 scuba divers at any point during the dive
  • Make dives which do not require in-water decompression stops
  • Dive only when appropriate support is available at the surface
  • Dive under conditions that are equal or better than the conditions where they were trained
  • If accompanied by a scuba instructor, a scuba diver at level 1 may gain progressive experience beyond these parameters and develop competency in managing more challenging diving conditions designed to lead to higher qualifications

 

 

Autonomous Diver
Minimize

EN 14153-2 / ISO 24801-2 specifies the competencies that a scuba diver has to have achieved in order for a service provider to award the scuba diver certification indicating that he has met or exceeded scuba diver level 2 – “Autonomous diver” and assessment of these competencies.

 

A scuba diver at level 2 – "Autonomous Diver" shall be trained to have sufficient knowledge, skill and experience to dive with other scuba divers of at least the same level in open water without supervision of a scuba instructor.

 

Scuba divers at level 2 – "Autonomous Diver" are qualified to dive within the following parameters unless they have additional training or are accompanied by a dive leader:

  • Dive to a recommended maximum depth of 20 m with other scuba divers of the same level, make dives, which do not require in-water decompression stops
  • Dive only when appropriate support is available at the surface, dive under conditions that are equal or better than the conditions where they were trained
  • If diving conditions are significantly different from those previously experienced, a scuba diver at level 2 "Autonomous Diver" requires an appropriate orientation from a dive leader
  • If accompanied by a scuba instructor, a scuba diver at level 2 – "Autonomous Diver" may gain progressive experience beyond these parameters and develop competency in managing more challenging diving conditions (e.g. increased depth and current, reduced visibility, extreme temperatures) designed to lead to higher qualifications
Dive Leader
Minimize

EN 14153-3 / ISO 24801-3 specifies the competencies that a scuba diver has to have achieved in order for a service provider to award the scuba diver certification indicating that he has met or exceeded scuba diver level 3 – “Dive leader” and specifies assessment of these competencies.

 

Scuba divers at level 3 – "Dive Leader" shall be trained to have sufficient knowledge, skill and experience to plan, organise and conduct their dives and lead other recreational scuba divers in open water.

 

Scuba divers at level 3 – "Dive Leader" are qualified to

  • Conduct any specialised recreational scuba diving activities for which they have received appropriate training
  • Plan and execute emergency procedures appropriate for the diving environment and activities
  • If diving and environmental conditions are significantly different from those previously experienced, a scuba diver at level 3 – "Dive Leader" requires an appropriate orientation with regard to local environmental conditions
  • In order to lead scuba divers on dives which have more demanding operational parameters a scuba diver at level 3 – "Dive Leader" shall have appropriate specialised training and experience
