Context of and specific resources for assessment:

Where, for reasons of safety, access to equipment and resources and space, assessment takes place away from the workplace, simulations should be used to represent workplace conditions as closely as possible

Resources essential for assessment include:

access to dental radiographic imaging units and resources normally used in the workplace

radiographic viewing equipment

Competency in this unit should be assessed using all the relevant resources commonly provided in dental practice. Specific resources may include:

relevant dental practice/organisation policy and procedures manuals such as:
