Prepare roof for re-tiling - GET3356

Duration

6 hours guided learning

Purpose/scope

The purpose of this standard is to provide the delegate with the knowledge and/or skills to focus on the use and application of the underpinning historical, technological and theoretical knowledge and the requisite practical skills to undertake the correct evaluation and selection of materials, tools, equipment and craft practices relevant to the preparation of roofs for re-tiling.

Scope:

• calculate the quantities
• metric and imperial tiles
• battens, spacing and position
• fixings
• gauging stick

Occupational relevance

Training delivered against this standard would be relevant to the following occupational group(s):

• operative and craft
• supervision
• leadership and management

Delegates pre-requisites

Delegates must have successfully completed NVQ level 2 (Roof Slating and Tiling)

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)
• at least 5 years industrial experience relevant to the scope of the standard
• a verifiable CV

Delivery

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 learning environment, 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:

• face to face learning environment only (such as classroom/workshop etc.)

This standard is predominantly practical 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.

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

• multiple choice questions
• short answer questions
• 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.

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.

Classification

Lifetime (Please note standards using this classification will only be grant aided once per delegate) 

Approval date

February 2023

Review cycle

On request or 5 years from approval date

Learning outcomes

Including additional guidance to support training delivery and final assessment
