• recorded professional discussion
• portfolio / workbook of workplace products / outputs
• observed oral presentations / briefings
• scenarios and case studies of realistic working environments
• integrated written assignments
• practical assessment

Quality assurance

Assured

Quality assurance against this standard will require initial approval of the training organisation and their content mapped to the standard.

CITB will also conduct an approval intervention, either desk-based or centre visit, to ensure the training organisation can meet the requirements of the training standard.
