National Occupational Standards

National Occupational Standards (NOS) provide benchmarks for competent performance. The content is led by demand and based on evidence from industry. The NOS underpin vocational training, apprenticeships, frameworks and qualifications across the UK, in all sectors and occupations. CITB develops and maintains these standards for the construction industry.

You can use these National Occupational Standards to:

  • Describe good practice in particular areas of work
  • Set out a statement of competence
  • Provide resource for a variety of workforce management and quality control tools
  • Offer a framework for training and development.

The standards are compiled in 'suites' under occupational areas and can be viewed individually on the National Occupational Standards database.

National Occupational Standards under review

The suites in development in 2022-2023 are:

  • Roofing Occupations
  • Floorcovering Occupations
  • Waterproof Membrane Roofing Systems
  • Tunnelling Operations
  • Site Logistics
  • Piling Operations
  • Formwork
  • Mastic Asphalt
  • Rainscreen Cladding Occupations
  • Fitted Interiors

If you would like to be involved or contribute to the updating of these suites of NOS please forward any comments/suggestions to standards.qualifications@citb.co.uk

Off-the-job training

To pass an NVQ or unit for qualification successfully, learners have to provide work-based evidence of their ability. For a limited number of additional items in a unit, it is possible to show their skills in a simulated environment (off-the-job) - although this must be conducted according to assessment regulations.
