5.4 Validity
A VTS qualification should be valid until either:
1. an annual assessment indicates that the holder
has fallen below the standards set by the Competent
Authority for operator qualifications; or,
2. there is a break in carrying out the duties for a
period of six months, or such shorter period as may be
required by the Competent Authority concerned, except for
any additional VTS training which might arise.
5.5 Annual assessment
An assessment of the performance of each VTS
Operator should be carried out by a VTS Supervisor at annual
intervals to ensure that the standards set by the Competent
Authority for operator qualifications are continuing to be
met.
5.6 Revalidation
Revalidation is required if either of the conditions
described in section 5.4 occur. The revalidation should
ensure the holder of a VTS Operator qualification continues
to maintain professional competence by one of the following
methods:
1 . An evaluation by an on-the-job training
instructor; or,
2. Successful completion of an advancement training
course; or,
3. A revalidation assessment by a board convened by
the VTS Authority.
5.7 Qualifications of instructors and assessors
Competent Authorities should ensure that instructors
and assessors are appropriately qualified and experienced for
the particular training and assessment of competence for
which they are given responsibility. Instructors for basic
and on-the-job training should hold suitable professional and
academic qualifications. However, on-the-job instructors may
not need the same level of academic qualifications as basic
training instructors.
