About National Occupational Standards (NOS)

Each NOS describes the knowledge, skills and understanding a person needs in order to be competent.

The standards-based method to competence (ability, aptitude, capability, skill and know-how) began with the development of National Vocational Qualifications (NVQs)/Scottish Vocational Qualifications (SVQs) in the mid to late 1980s.

The industry-specific standards that formed the basis of those qualifications became known as National Occupational Standards (NOS) and later on the NOS were recognised as an important product in their own right.

NOS suites are made up of a number of standards and these standards are currently available by contacting standards.qualifications@citb.co.uk or by visiting the NOS Database.

The construction industry’s Craft (trade) NOS, as well as the  Technical, Supervisory and Management NOS are developed and maintained by ConstructionSkills by working closely with industry through employer-led meetings.

National Occupational Standards are used 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
  • form the basis of all qualification frameworks.

Development and Maintenance of NOS

NOS are developed and maintained through a programme of reviews and incremental change cases. If you would like to see which suites are being reviewed or have incremental changes logged, then please view the current activity in a specific occupational area through NOS occupations and revisions

Please click on the 'NOS presentation' link below this paragraph to see the presentation given by Developers to everyone who is invited to contribute to the development and revision of NOS.
