FAQs
Do I need any previous experience or prerequisites to study the Lean Six Sigma Yellow Belt course?
No previous experience or prior qualifications are required to study the Lean Six Sigma Yellow Belt course. The course has no formal prerequisites, making it suitable for anyone who wants a recognised introduction to Lean Six Sigma principles and process improvement methods.
Because the Yellow Belt is designed as a foundation-level qualification, it is well suited to a wide range of professionals, including:
- Staff involved in process, service, or operations improvement
- Team members supporting Lean Six Sigma or Kaizen projects
- Managers and supervisors who want a shared language for continuous improvement
- Professionals in functions such as HR, IT, finance, or customer service
The course begins with the philosophy and history of Lean and Six Sigma, so no prior knowledge of either methodology is assumed. Content builds progressively through topics such as DMAIC, PDCA, Voice of the Customer (VOC), process mapping, and basic root-cause analysis tools.
The APMG-accredited Yellow Belt exam also carries no prerequisites. It is an open-book, 60-minute, multiple-choice assessment of 50 questions, with a pass mark of 64%. Results are available on the same day.
If you already have some familiarity with Lean Six Sigma or need to lead improvement projects and analyse data, the Lean Six Sigma Green Belt course may be a more appropriate starting point to consider.
How do I take the Lean Six Sigma Yellow Belt exam?
The Lean Six Sigma Yellow Belt exam is taken online through the APMG International Candidate Portal, and you can sit it as soon as you feel ready during your course access period.
Here is what to expect from the exam format and process:
- Format: Multiple choice (objective test)
- Questions: 50
- Pass mark: 64% (32 out of 50 correct)
- Duration: 60 minutes
- Open book: Yes – you may refer to your materials during the exam
- Prerequisites: None

To access the exam, every candidate registers for a free APMG Candidate Portal account. This is where you book your exam, view your result, download your certificate, and claim a digital badge via a linked Credly account. Digital badges and electronic certificates are available within two business days of your result being issued.
The exam is included in the cost of the Knowledge Train Lean Six Sigma Yellow Belt course, and the APMG-accredited Yellow Belt certification does not expire, so there is no renewal requirement once you pass.
When will I receive my Lean Six Sigma Yellow Belt exam results and certificate?
You will receive a provisional result immediately after completing your Lean Six Sigma Yellow Belt exam online, with your official result and certificate available through the APMG Candidate Portal within approximately two working days.
Here is how the process works after you finish your exam:
- Provisional result – same day: Your pass or fail result is displayed as soon as you submit your online exam.

Is Lean Six Sigma Yellow Belt hard to pass?
The Lean Six Sigma Yellow Belt exam is considered accessible for most learners, with Knowledge Train reporting a 99% pass rate among its students.
The APMG-accredited Yellow Belt exam is structured as follows:
- Format: Multiple choice (50 questions)
- Pass mark: 64% – you need to answer 32 out of 50 questions correctly
- Duration: 60 minutes
- Open book: Yes – you can refer to your materials during the exam
- Prerequisites: None
The open-book format significantly reduces the pressure of memorising terminology, and the pass mark of 64% is achievable for learners who engage with the course content. The self-paced online course from Knowledge Train includes 10 hours of interactive content covering the core topics tested – such as DMAIC, PDCA, Voice of the Customer, 5S, and basic root-cause analysis tools.
The Yellow Belt is designed as an introductory qualification, suitable for people new to Lean Six Sigma with no prior experience. It is not as demanding as the Green Belt (3-hour exam) or Black Belt (3-hour exam), which require considerably deeper knowledge and a longer study commitment.
If you do not pass first time, an exam resit is available, though an additional resit fee applies. Results are available on the same day via the APMG Candidate Portal.
Can I retake the Lean Six Sigma Yellow Belt exam if I fail, and does it cost extra?
Yes, you can retake the Lean Six Sigma Yellow Belt exam if you do not pass, but an additional exam resit fee applies.
The APMG-accredited Lean Six Sigma Yellow Belt exam is included in the course fee when you enrol with Knowledge Train. If you sit the exam and do not achieve the pass mark of 64% (32 out of 50 questions), you are eligible to resit. However, the resit is not covered by the original course price – you will need to pay a separate resit fee to book another attempt.
A few practical points worth knowing before you sit:
- Exam format: 50 multiple-choice questions, 60 minutes, open book – you can refer to your materials during the exam.
- Pass mark: 64% (32 correct answers out of 50).
- Results: Provisional results are available the same day via the APMG Candidate Portal.
- Preparation support: Knowledge Train provides tutor and technical support by email and phone throughout your 12-month access period, which can help you prepare thoroughly before your first attempt.
The open-book format and the availability of tutor support mean most learners are well-placed to pass at the first attempt. Knowledge Train reports a 99% pass rate for this course.
