The COSS workplace assessment is for existing Sentinel card holders endorsed with probationary COSS to convert into full COSS within 4 months of a COSS course. Individuals who wish to maintain their certification must successfully complete COSS assessments. If a person fails to carry out their assessment within the correct timescale, they lose the competency and will have to undergo initial training to regain the competency. This workplace assessment incorporates Overhead Line and Conductor Rail Permit modules OLP/CRP/LLT.

Additional Information

It is advised that the COSS assessment is booked well in advance of expiry to avoid losing your competence, as there is no grace period from Sentinel for workplace assessments.
