National Occupational Standards (NOS)
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, apprenticeship frameworks and qualifications across the UK, in all sectors and occupations. As the Standards Setting Body for construction, CITB develops and maintains these standards for the construction industry.
Although NOS are often used to build qualifications and training programmes, sectors, organisations or individuals can use NOS as the platform for almost any other aspect of human resource management and development, for example:
workforce planning
performance appraisal and development systems
job descriptions
workplace coaching
reflective practice
The standards are compiled in 'suites' under occupational areas and can be viewed individually on the National Occupational Standards database.
