PREVIEW: Natural slating


Overview
This preview is for ATOs only. The purpose of this standard is to provide the candidate with the knowledge and skills to install natural slates for a new roof, including the: membrane, battens, flashing, and fittings.

This standard is available to ATOs to preview before it’s finally published. You should make sure your course matches these details. This standard will eventually supersede the existing standard in development. 

Until then, continue to publicise your courses against the existing title on the Construction Training Directory.

CITB has developed this standard in discussion with industry

Duration

  • clean up and dispose of waste materials

Occupational relevance

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

  • operative and craft.

Candidate prerequisites

There are no candidate pre-requisites as part of this standard. However, a basic knowledge of slate and/or tiling roofing terminology and techniques would be beneficial.

Before candidates perform the work on a construction site, candidates must have successfully completed roofing-specific training for working safely at height.

Instruction / supervision

As a minimum, course instructors must be able to demonstrate that, in relation to this standard, they have:

  • A train the trainer or instructional techniques course certificate
  • Successfully completed training to this standard 
  • At least 2 years relevant industrial experience
  • A verifiable CV.

Delivery

The following method(s) may be used in the delivery of this standard:

  • classroom and workshop

All materials and equipment must be of a suitable quality and quantity for candidates to achieve learning outcomes, and must comply with relevant legislation.

The class size and candidate/instructor ratio must allow training to be delivered in a safe manner and enable candidates to achieve the learning outcomes.

This standard is considered to contain 51 per cent or more theoretical learning.

Assessment

For the successful completion of training, candidates must complete an end of course practical assessment or knowledge test that measures the learning outcomes and has a pass or fail criteria.

Quality assurance

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/refresher

There are no mandatory renewal or recommended refreshment requirements for this standard.

Approval date

TBC

Review cycle

Either on request or in 3 years from approval date.
