    REREGISTRATION HISTORY 
    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    SAMSA Assessment procedure:
  • Every learner for the issue of a certificate of competency as deck or engineer officer must be assessed at one or more of the following levels:
    > Level 1; this assessment is carried out during qualifying service on a ship and involves the practical demonstration that the required level of competency has been reached or during training at an accredited institution, and must be carried out aboard ship by one or more designated ship's officers and ashore by one or more assessors.
    > Level 2; this assessment is carried out during qualifying service on a ship or during training at an accredited training institution, and must be carried out by an assessor.
    > Level 3; this assessment is carried out by an examiner and an assessor when a learner presents himself or herself for oral examination.
  • All units of competency that are to be assessed at level 1 or 2 must be indicated in the training record book issued to the learner.
  • Only an assessor may sign off a unit of competency in the learner's training record book when the learner is considered to be ready for the next level of assessment (if any) and has successfully demonstrated competency in the unit as specified in the Code for South African Maritime Qualifications (the Code).

    Terminology:

    All terms used in this unit standard are consistent with terms generally used in a marine engineering environment and do not require further clarification. Acronyms used have been written out in full the first time they appear in this document.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
