ISO 23678-4:2022

This document establishes a **uniform, safe and consistent approach** to the in-field competence assessment of personnel for the maintenance, thorough examination, operational testing, overhaul and repair of lifeboats and rescue boats, launching appliances and release gear.

It also provides the necessary information for interested parties to grant authorization, effectively evaluate and audit training, supporting the IMO Requirements, section 3.

It specifies the level 2 in-field initial and ongoing competence assessment for personnel certified by a manufacturer or an authorized service provider to carry out maintenance, thorough examination, operational testing, overhaul and repair of lifeboats (including free-fall lifeboats) and rescue boats (including fast rescue boats), launching appliances and release gear.

The training an individual receives while following a development process is covered in **ISO 23678-2** and **ISO 23678-3**.

The competence requirements contained in this document provide a clear description of performance in-field in respect to:

• a) what practitioners are expected to do;
• b) the underpinning knowledge and skills they require to enable them to do what is expected;
• c) how they can demonstrate what is expected of them;
• d) how their performance can be assessed.

This document is intended to be used in conjunction with ISO 23678-1, ISO 23678-2 and ISO 23678-3.
