Assessment Criteria for Watermanship evaluation[edit | edit source]

Watermanship evaluation[edit | edit source]

  • Two alternative tests are available. The candidate may choose which alternative to attempt
  • This test should be done in benign water in swimming costume without buoyancy aids. Swim goggles. nose clip , swim cap or thin hood and/or half mask may be worn. If temperatures are too cold a heated pool may be used. The candidate should not be exposed to conditions which will cause failure due to hypothermia. (particularly for alternative b)
  • The entire test must be done without interruption or delay between items.
  • The test may be repeated as many times as may be necessary until successfully completed. Each attempt must start with item 1 and continue until all items are successfully completed in the listed order. An adequate break should be allowed between attempts.
  • This test should be successfully completed before the learner starts with in-water training. Variations from this point are at the discretion and responsibility of the course director and should be guided by considerations of health and safety of the learner.
  • These skills are prerequisites for diver training. The diving school is not obliged to teach swimming skills.
Alternative "a"
Item
No.
Description
1 25 m underwater swim from a standing start (in water)
2 300 m free style (To be completed within 10 minutes)

5 60 seconds treading water with hands on head
6 30 seconds rest period
7 20 second breath hold with head submerged
Alternative "b"
Item
No.
Description
1 25 m underwater swim from a standing start
2 300 m free style (To be completed within 10 minutes)
3 100 m back stroke
4 "Drown proof" for 15min (stay afloat without holding the sides of the pool).
5 30 seconds rest period
6 20 second breath hold with head submerged (timed by assessor)

General criteria for Surface Supplied Diving skills assessment[edit | edit source]

  • As a general principle competence in a composite skill implies competence in the component skills. RPL assessment should target the composite skill to save time.
  • Skills must be practiced and assessed until each one can be performed competently.
  • If the assessor has any doubts that a critical skill can be consistently performed the skill should be demonstrated competently 3 times in succession
  • RPL assessment may be done in open water.
  • Several skills may be assessed together when convenient (integrated assessment).
  • Any practicable combination of these skills may be summatively assessed during an open water dive.
  • Whenever practicable the skill should be personally observed by the assessor. This may be done by diving with the candidate/learner, through a window in a tank, via CCTV or by video recording. Where this is not possible, another instructor or assistant instructor should observe the demonstration. The assessor/instructor is not required to dive using the same mode as the learner.

Tasks done by divers

Required range of Surface Supplied Diving experience[edit | edit source]

  • Bottom time follows the definition in the US Navy decompression tables. It is the time from when the diver leaves the surface to when the diver leaves the bottom to start his ascent to the surface. Descent time is included in bottom time. Ascent and decompression time is not. Ascent starts when the tasks/exercises are complete, and the diver has reached a place where movement towards the surface at approximately the required rate can be started. Lateral movement is included in bottom time. Delays in ascent below the first decompression stop will generally be considered part of bottom time. In case of dispute, the US Navy tables or other approved decompression tables in use for the operation will be considered authoritative.
  • Where a number of dives for a given experience is specified those dives MAY NOT BE COMBINED. An exit from the water and removal of helmet/FFM (preferred) or a ten minute surface interval (if exit is not reasonably practicable) is the minimum acceptable separation between dives.
  • A surface interval of at least 10 minutes between dives is recommended but not compulsory if the diver has exited and removed helmet or mask.
  • As a general principle, any dive that has a minimum time specified may be made up by two or more dives with the same accumulated bottom time using the specified equipment and doing the specified tasks. When more than one dive for specified tasks is required, the specified total time and minimum number of dives must both be complied with.
  • Order of exercises may vary from that listed below provided that conditions specified in each exercise are met. This applies particularly to depth range requirements for each type of breathing apparatus.
  • The use of a downloadable bottom timer or decompression computer can provide a useful record of the dive profile and is strongly recommended.
  • If you think that the number of dives required is not important, or that a specific exercise is not useful, or that an exercise should be added, or any other change should be made, apply to the DoL in writing with detailed and reasoned motivation for the standard to be amended.
  • If you think that the school has interpreted a requirement incorrectly, provide a detailed explanation of what you consider to be the correct, or at least a better interpretation, including your reasons, preferably in writing.

Useful results should be produced within the context of the briefing
Many digital still cameras have a video facility, and many digital video recorders have a still photo facility, so it will often be possible to do combined tasks
External lighting and flash should be provided when conditions warrant.
Camera or video 2
As for camera or video 1
Hand tool assembly 1
A specification of two spanners per task and a depth of more than 10 m is given. This depth requirement has no apparent benefit. However, though apparently pointless, it is at least not onerous, and should not cause undue difficulty, as the task requirement is in any case trivial. It is recommended that more than two hand tool tasks be provided during the training programme, as divers generally like to have something to do underwater.
A wider range of tools is suggested
At least one of the hand tool dives should involve assembly using spanners
Hand tool assembly 2
As hand tool assembly 1
Inspection and report 1
Take measurements of an underwater object or site and make any sketches necessary
A depth of at least 20m is specified. This may be to allow the influence of nitrogen narcosis and if so this is a reasonable requirement.
Produce a written report on the inspection after the dive using the measurements, and if appropriate a drawing and or photographs and/or video (see practical tasks Camera or video 1 and 2)
It is suggested that other inspection tasks be set to provide useful learning opportunities for divers when there is no other task to be done.

30m dive 2
As for 30m dive 1
Chamber dive 50m

Optional extra dive tasks:[edit | edit source]

These tasks are not currently compulsory, however they are recommended as additional tasks when the divers are required to get more dive time, or combined with required tasks, so they spend their time doing something which extends their learning opportunities. A training dive should always have at least one task or assessment. Dive time should not be wasted.
