- management and leadership
Delegate pre-requisites
There are no delegate pre-requisites as part of this standard.
Instruction/ supervision
As a minimum, course trainers must be able to demonstrate that, in relation to this standard, they have:
- an award in education and training (or equivalent, as per requirements for approved training organisations)
- successfully completed training to this standard
- at least 5 years relevant industrial experience
- a verifiable CV
Delivery
Delivery may be in an on or off the job environment.
All materials and equipment must be of a suitable quality and quantity for delegates to achieve learning outcomes and must comply with relevant legislation.
The class size and delegate/trainer ratio must allow training to be delivered in a safe manner and enable delegates to achieve the learning outcomes.
The following delivery methods may be used in the delivery of this standard:
- classroom
- a blend of classroom and remote
- remote
This standard is considered to contain 51% or more theoretical training.
This standard is considered to be set at an advanced level.
Assessment
For the successful completion of training, delegates must complete an end of course practical assessment or knowledge test that measures all learning outcomes and has a pass or fail criteria.
Where this training is assessed using multiple-choice questions, a minimum of 10 questions must be asked and delegates are required to achieve an overall pass mark of at least 80%.
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.
Approved training organisations (ATOs) will be required to present information on records of training and assessment upon request to CITB for desk-based analysis. They will also be visited annually by the CITB quality assurance team.
Renewal
There are no mandatory renewal or recommended refresher requirements for this standard.
