operative and craft.

Delegates pre-requisites

Delegates must have successfully completed training to the Traditional screeds standard 3 years prior to attending this refresher.

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 2 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.

This standard is considered to be set at an intermediate level.

Assessment

Methods of assessment considered appropriate for training delivered against this standard are:

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.
