What are National Occupational Standards (NOS)?

As an assessor, your role is to judge whether a learner meets a clearly defined standard. These standards often come from something called National Occupational Standards (NOS) — a fundamental part of regulated qualifications, including First Aid.


🧾 What Are National Occupational Standards?

  • NOS are statements of the level of performance an individual must achieve when carrying out tasks in a specific job or role.
  • They also include the knowledge and understanding required to support that performance.

🔍 Key Characteristics of NOS:

  • They are National – recognised and used across the UK.
  • They are Occupational – tailored to specific job roles (e.g. first aider, trainer, assessor).
  • They are Standards – benchmarked expectations agreed by employers and industry experts.

🧠 Why NOS Matter to Assessors:

  • NOS form the basis of many regulated qualifications and their assessment criteria.
  • They help ensure that assessments are:
    • Relevant to the learner’s role
    • Aligned with industry expectations
    • Transparent and consistent
  • Understanding NOS helps you assess more accurately and justify your decisions if required.

✅ Example:

If you are assessing a learner for a first aid qualification, the assessment criteria may be directly mapped to NOS that describe what a competent first aider must be able to do and understand in real-life situations.


Reflection: Have a look at the NOS that relate to your subject area — can you see how they influence the content of the qualifications you deliver?
