Assessment Guidelines for TABLE A-II/1

Officer in Charge of a Navigational Watch

on ships of 500 gross tonnage or more

Skills that must be demonstrated:

1.

Skill demonstrations

These assessment guidelines establish the conditions under which the assessment will occur, the performance or behavior the candidate is to accomplish,

and the standards against which the performance is measured. The assessor is encouraged to use a checklist in conducting assessments of practical

demonstrations of skill. Checklists allow a training institution or qualified assessor to ensure that critical tasks are not overlooked when evaluating a

candidates practical demonstration. Training institutions and qualified assessors should develop their own checklists for use in conducting the assessments

in a complete and structured manner.

Notes

Note 1 For ocean routes only

Note 2 Required for officer in charge of a navigation watch of vessels greater than 3,000 GT (ITC)

Note 3 Not required for mariners serving exclusively on vessels not fitted with ARPA, a limited endorsement will be made to the MMC reflecting this.

Note 4 -- Not required for mariners serving exclusively on vessels not fitted with RADAR, a limited endorsement will be made to the MMC reflecting this.

Note 5 -- Not required for mariners serving exclusively on vessels not fitted with ECDIS, a limited endorsement will be made to the MMC reflecting this.

Non- Italicized font under performance conditions, performance behaviors and

performance standards are tasks that currently exist in NVICs and Policy Letters.

These can be revisited and upgraded due to lessons learned.

Italicized font under performance conditions, performance behaviors and

performance standards are tasks that will be coming into existence. The italicized

tasks are either STCW generalities of the tasks to be performed OR tasks that

have been developed, in house, to meet those STCW generalities. These need to

be developed or developed further.
