    6 Best IASSC Certifications That Pay Well in 2024

    Six Sigma certifications are highly regarded and recognized globally for their focus on process improvement, problem-solving, and quality management, which makes getting a Six Sigma certification the ideal way to move forward in your career in the quality domain.

    From my experience, I can tell you that every Six Sigma professional takes Six Sigma Certifications very seriously. These certifications can be one of the best investments in your career path. Several well-known organizations worldwide offer these certifications. Some of these respected certifying bodies include The American Society for Quality (ASQ), the International Association for Six Sigma Certification (IASSC), Villanova, and GE.

    In this article, let’s take a close look at the top six IASSC certifications given by the International Association for Six Sigma Certification (IASSC). We'll explore what IASSC certification involves, why it's an excellent choice, the different certification levels, how much each one costs, high-paying job opportunities with an IASSC certification, and more.

    What is IASSC?

    International Association for Six Sigma Certification is a certifying body that offers certifications for professionals to gain knowledge on Six Sigma skills and methodologies. In my opinion, getting a Six Sigma IASSC certificate is considered highly credible and widely recognized globally. Applying the knowledge gained from these certifications, you can drive various Lean Six Sigma projects in your organization.

    IASSC certifications in Lean Six Sigma such as the Six Sigma Green Belt Certification, and the Six Sigma Black Belt are the most sought-after certifications to name a few. IASSC does not offer any coaching or training to professionals taking these certifications but has partnered with multiple training providers globally.

    What are IASSC Certifications in the field of Lean Six Sigma

    Before going into the details of Lean Six Sigma certifications offered by IASSC, let me brief you on the Lean Six Sigma methodology. Lean Six Sigma is a Six Sigma methodology that focuses on reducing waste and improving efficiency.

    To make it simpler let me give you an example of Lean Six Sigma process improvement methodology. Imagine a fast-food chain that makes customers wait for a long time to get their orders. This makes customers leave the restaurant, which in turn affects the reputation of the fast-food chain. Applying Lean Six Sigma principles, the problem can be defined as what causes the delay in orders. Once the problem is identified, the right steps can be taken to come to a solution by applying the DMAIC (Define, Measure, Analyze, Improve, Control) methodology.

    The International Association for Six Sigma Certification specializes in Lean Six Sigma certifications. These IASSC certifications help individuals showcase their knowledge and skills through process improvement projects. Their certifications include the Lean Six Sigma Green Belt, the Lean Six Sigma Black Belt, etc. Hence the certifications by IASSC are extremely useful for quality professionals looking for advanced techniques.

    Benefits of Earning IASSC Certifications

    Having an IASSC certification makes you a credible expert in the Lean Six Sigma principles and practices. I am going to list the benefits of getting Lean Six Sigma certified.

    Benefits of Earning an IASSC Certification:

    • With an IASSC Lean Six Sigma certification, you are in a better position in terms of your career growth. You will open doors for various opportunities to lead six sigma projects and mentor teams to identify process improvement areas in their respective work field.

    Different IASSC Certification Pathways

    IASSC offers two types of certifications, the first being the Lean Six Sigma certifications and the second being the Lean certification. Lean Six Sigma certifications focus on using lean principles integrated with six sigma tools and methodology. On the other hand, Lean certification focuses on Lean principles which strive for continuous improvement and reduction of waste.

    1. Lean Six Sigma Certifications

    Lean Six Sigma methodology follows the DMAIC process improvement framework and is focused on continuous improvement and reducing wastage. IASSC offers four Lean Six Sigma certifications for any individual striving to learn the Lean Six Sigma principles and techniques and apply them within their organization. They are the Lean Six Sigma Black Belt, the Lean Six Sigma Green Belt, and The Lean Six Sigma Yellow. Each Six Sigma certification offers training and skills pertaining to that particular level. For example, the Black Belt certified professionals go through rigorous training to lead complex six sigma projects. 

    2. Lean Certification

    Lean certifications as the name suggests are credentials provided by IASSC to professionals wanting to learn the lean principles. The Lean principles streamline processes and ensure minimal variation. Lean methodology focuses on streamlining processes to minimize variation and reducing wastage by applying lean principles like Value, Value Stream, Flow, Pull, and Perfection. It uses quality methodologies like 5S, Kaizen, and Value Stream Mapping, etc. Lean Expert, Lean Leader, and Lean Practitioner are the three types of Lean certifications offered by IASSC.
