Lean Six Sigma Certification

We see Lean Six Sigma (when “done right”) as a key enabler of Excellence and set up the The BQF Academy over 10 years ago. We recognised the role we could play in supporting our members, as well as other organisations, by ensuring that a rigorous and impartial system was set up to certify Lean Six Sigma practitioners.

Working with leading businesses and specialist consultancies, the Academy developed the standards at each level and operates a certification process for five Lean Six Sigma practitioner levels and four Lean practitioner levels.

Our fundamental principle is that candidates must be able to demonstrate successful practical application of the methods, not simply pass an exam.

Our certification register currently lists over 6500 Green Belts, over 1500 Black Belts and almost 300 Master Black Belts from major companies in the private and public sectors in the UK, Europe and beyond.

Lean Six Sigma Certification is offered at FIVE levels:

Yellow Belt, Green Belt, Black Belt, Master Black Belt and Project Champion.

Lean Certification is offered at FOUR levels:

Associate, Practitioner, Advanced Practitioner and Master Practitioner.

Certification is a three step process for each:

  • Complete appropriate training.
  • Pass the exam at the relevant level.
  • Present evidence of practice for assessment.

Successful candidates receive a written feedback report and certificate, and join our official Certification Register. Setting high performance expectations, the Academy has certified 1,000s of LSS candidates.

Your certification does not expire. However, many individuals and businesses value being able to demonstrate continued professional development, and so we have introduced a new process where you will need to submit documentation of your learning and practice activities to implement a License of Current Practice, which is issued with your certificate and can then be reactivated every three years.

You can find out more and submit your documentation on the Certification Register.

  • Your certificate remains valid forever (as a Degree certificate would for example).
  • After three years, although it is not compulsory, we do advise you to reactivate your licence to demonstrate you are up to date with current Lean Six Sigma practice.
  • To do this you will need to provide evidence that you have undertaken continued professional development in Lean Six Sigma over the last three years. You will then remain ‘active’ on the certification register.
  • If you do not renew your licence within the three years you will appear as ‘inactive’ on the certification register.

For more information about how to reactivate your licence please see the Certification Register page.

There are many organisations offering Lean Six Sigma and Lean certification – why should I choose BQF?

We understand that this is a source of frustration for individuals and businesses. Some points for you to consider are:

  • Is the certification based on exam only or does it include the assessment of how you put the skills into practice?
  • If the certifying body is the same as the organisation providing your training your certification may be seen as less valid
  • Who is the ultimate authority behind the certification?
  • To what degree will this certification enhance my CV?
  • Will current/future employers recognise or value this certification?

Does my GB/BB/MBB certificate expire?

No. The principle is the same as, for example, a university degree certificate.  This certifies that you achieved this qualification on the date shown on your certificate but does not indicate whether you have maintained and further developed your skills since that date.

Is online training accepted for acquisition of knowledge?

Yes, provided it meets the same criteria as classroom training and can be evidenced as described.

Is internal company delivered training accepted?

Yes, provided it is a formal course endorsed by your company’s training department and can be evidenced as described.

Could you define “recognised, reputable (training) organisation”?

It would be unfair for us to insist that only officially accredited BQF training organisations can provide training for these purposes but we also need to protect the integrity of the licence. We suggest that you use good judgement when selecting training providers. We reserve the right to refuse to accept training certificates from organisations whose credentials we cannot satisfy ourselves are acceptable.

How will I receive my certificate?

An electronic certificate (via ‘Accredible’) will be emailed to you along with instructions on how to take full advantage of your digital certificate. Electronic certificates can then be added to LinkedIn, shared via social media or downloaded as a PDF.
