RSS 18404 for individuals

If you are involved in delivering Six Sigma projects and/or Lean improvement, or you wish to develop your skills in these areas, you can now gain RSS 18404 certification. Certification by the RSS should be your ultimate goal as it demonstrates that you have attained the level of skills and competencies outlined in the ISO 18404 standard.

As an individual, you can gain certification in two ways: working as a green belt/lean practitioner in a RSS 18404 certified organisation and having been assessed by your employer; or by attending and passing a RSS assessment centre. If you are taking your first steps in this area, you should attend training courses to develop your skills. We run courses at all levels, designed to prepare you to pass our assessment centres. 

Once you’ve successfully achieved RSS 18404 certification, you will automatically be eligible to join the RSS register, giving you your own unique certification number.

Benefits of RSS 18404 certification include:

  • A recognised and official certification based on rigorous testing and assessment of competence against ISO 18404
  • Inclusion of RSS 18404 certification on your CVs will give you a competitive edge in the labour market
  • Ability to check the RSS register for organisations who are certified, giving you confidence they have Lean/Six Sigma methods which will enable you to use your skills
