GENERAL The technical skills assessor is the person who is considered suitable to determine whether an ATSEP is technically competent to operate, maintain, release from and return into operations systems that are necessary for the provision of services. This assessment may be in any context where assessment of technical skills is required, e.g. assessment of first competence, ongoing competence.

ASSESSMENT RESPONSIBILITIES

(a)Where a technical-skill assessor works regularly with an ATSEP and he or she is required to assess the ATSEP, then continuous assessment may be appropriate, i.e. assessment may be achieved by the technical assessor observing the standard of an ATSEP’s work on a continuous basis during normal operational duties. In that case, the technical-skill assessor should inform the ATSEP of when they will be assessed.

(b)If the appointed technical assessor also acts as line manager to the individual ATSEP, the service provider should have in place a process to reduce biases. Responsibility for determining competence lies with the person having the safety accountability for the ATSEP function.
