    I found the (Lean Six Sigma Green Belt) course both challenging and rewarding, completing the practical assessment project was a great opportunity to put the tools learnt into real time practice with positive results for the company.

    I had a great experience working with APMG on my LSS Black Belt. The process was efficient and any questions I had were answered quickly. I would absolutely recommend APMG and LSSA for certification.

    SFIA

    The SFIA Framework is the global common reference for skills and competency for the digital world.

    This APMG certification has been informally mapped against the SFIA Framework to indicate the skills that are addressed and referenced by the certification. Although it is not yet possible to claim this digital badge, the indicative skills can be used to plan your professional development through assessing the skills you have and the skills you need for the role you want.

    FAQs

    Full details of our Equality Policy can be found on our website.

    Any request for additional time will need to be provided in writing to customerservice@apmgroup.co.uk. We will need to see evidence of your diagnosed condition in the form of a medical report, signed by a medical practitioner.  

    If this is not available, or your condition was diagnosed a long time ago, then any statement from an employer, line manager or Occupation Health advisor will be sufficient.  

    If no recommendations regarding the length of time to be added to the exam is evident in the documents supplied, then we apply 25% additional time to the exam.

    Please contact our 24/7 Technical Team on +44 (0)1494 452450 and select Option 3 for Technical Assistance or email them at help@apmg-international.com. They are also available via a live chat.  

    If this is a password creation issue, please note that '?', '@', '#', and 'é' are not allowed for creating a portal password.

    You can either contact your Training Organization to purchase a new exam, or you can purchase a new exam directly from our public exams website. For more information, see our more detailed article on resitting an exam.

    Using a company device in which you do not have administrative rights and access to download additional software tends to cause issues when sitting your exam via ProctorU, as outlined in the Candidate Guidance Agreement.  

    If you wish to sit your exam via ProctorU again, you will need to pay a reschedule fee of £32 (which you can do in the Candidate Portal) before you can select a new date and time.  

    Alternatively, you can reschedule your exam via our AIPP service, where you can take your exam over Zoom without downloading any additional software. Please note there are fewer exam slots available through AIPP.  

    Full details of our Proctoring options can be found on our Proctoring Page

    If you feel you had issues during your exam, you may submit an appeal to customerservice@apmgroup.co.uk. We will review your appeal and respond. See APMG’s policies for details on the full appeals process.

    To appeal your result, email a written request with supporting evidence to customerservice@apmgroup.co.uk. We will review your appeal and respond. See APMG’s policies for details on the full appeals process.

    Your results will be processed 6 to 12 hours after your exam. You will receive an email confirming your achievement and inviting you to the Candidate Portal where you can see your official result. From there, you can create your account in Credly.com and access your digital badge and certificate.

    Your training organization specified that they wish to view candidate results before releasing. If you would like your results sooner, you may contact your ATO directly and request your results that way. After they have released them, you will be able to create/view your Digital Badge and download your Digital Certificate in your Credly account in the Certificates section of your portal.

    Since 2018, we are no longer registered for AXELOS qualifications and are unable to provide the certificates.  

    If you received your AXELOS qualification before this time, you can contact customer service and upon providing your candidate number, ask if a copy of your certificate still exists in our system. 

    Alternatively, you can reach out to IT PeopleCert directly with this request quoting your candidate number.  

    If you do not have your candidate number, we can provide it to you. Additionally, we are happy to provide a letter of verification for any exams sat with us.
