CITB has developed this standard in discussion with industry
Minimum 1 day of 6 learning hours per day
Purpose / scope
The purpose of this standard is to provide the candidate with the knowledge and skills to install tiles over water-based and electrical-based heating systems, including: ceramic tiles, natural stone tiles, and resin agglomerated tiles.
The scope of this standard covers:
- types of heating system and substrate
- design considerations of joints, strips, and screeds
- design considerations for under tile systems
- how to install a water-based heating system
- how to install an electrical-based heating system
- how to select adhesive and grout
- preparation of the floor
- how to commission the heating system
- use of the floor in service
- how to work safely
- main legislation, codes of practice, guides, and standards
Training delivered against this standard is relevant to the following occupational group(s):
- operative and craft
There are no candidate pre-requisites as part of this standard. However, a basic knowledge of tiling terminology and techniques would be beneficial.
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.
The following method(s) may be used in the delivery of this standard:
- classroom and workshop
- on site in a safe and supervised environment
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 practical training.
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 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.
There are no mandatory renewal or recommended refreshment requirements for this standard.
Either on request or in 3 years from approval date.
The candidate will be able to
