VCAT-IV Expert Vibration Analyst
Achieve the highest status as a vibration analysis professional – capable of handling any condition that may be presented, capable of performing any test, fully understanding flexible rotor machinery - with advanced 3D animations and interactive simulations that make everything easy to understand.
Congratulations on being ready to tackle the Mount Everest of vibration analysis.
The good news is you are in the right place. We have developed an amazing set of 3D animations and simulations that even make the Category IV topics relatively easy to understand. Topics that were once only suitable for PhDs and math geniuses are now accessible to practical vibration analysts – as it should be.
There is a lot to learn. You are required to take 64 hours of training according to ISO 18436-2, but we provide over 80 hours with combined online learning and 5-day in person learning (including Day 5 optional certification exam). To make it easier to master all the topics on the syllabus, and to minimize travel and accommodation requirements, we have created videos that cover all the topics. You can watch them again and again until the topics and techniques are crystal clear.
When you are ready, you must attend the face-to-face course where the instructor will review the topics and take you through a series of “worked examples” until you feel ready for the exam.
This training process will ensure you understand the topics so that you can apply the techniques in your role as the expert vibration analysts.
This training process will also help you achieve the pinnacle of the vibration world – the ISO Category IV Vibration Analyst.

Like two courses in one
The topics are roughly broken into two groups:
- There is an entire course that could be called “Category III on steroids”. Many of the topics you covered in Category III are covered again but we go into more detail. Those topics include signal processing, dynamics, ODS, modal analysis, and so on.
- And then the course goes into overdrive. Now you get into the topics that are unique to Category IV. You will learn about fluid film bearings and flexible rotors, including measurements with proximity probes, diagnosing a variety of fault conditions, and even balancing flexible rotors.
Mobius animations and simulations to the rescue
Category IV does cover a lot of practical content, but there is a good dose of theory as well. It is the theory and the calculations that can intimidate many vibration analysts. But we have done our best to make it all understandable and achievable. We provide you with a long list of worked examples with clear explanations on how to perform the calculations. But we also have animations and simulations that let you understand exactly what is going on. Rather than abstract concepts that only PhDs feel comfortable with, you will be able to connect theory with reality because you will see it right there on the screen.
Once you complete the training, you can take the exam with confidence, and become certified to ISO 18436-2 Category IV via the internationally respected Mobius Institute Board of Certification™ [MIBoC]. The MIBoC certification is accredited to ISO/IEC 17024 – there is no higher standard. You will join thousands of other Mobius™ certified analysts around the world.
Why learn with Mobius Institute™?
There are three major reasons why over 4,000 vibration analysts choose Mobius Institute every year:
- We make complex topics simple with amazing 3D animations and simulations that make you say, “Ah, now I get it!”
- We give you access to the entire course before the class begins so you are better prepared, and for six months after the course, just in case you still have questions
- We use anonymous, stress-free polling throughout the course, so you know if you truly understand each topic, and the instructor knows not to move on to the next topic – no student is left behind
There are many other reasons why vibration analysts, and their managers, choose Mobius Institute.

- Being certified by an accredited certification organization is a major step up from simply passing a test. Yes, the process is a little more complicated and stricter, but that is for very good reasons
- The educational process is extremely valuable, but being certified tells an employer (or a consulting client) that you are capable of doing an important job
Mobius Institute has certified more vibration analysts than any other organization and we have only been offering certification since 2005. Almost 40,000 vibration analysts around the world, just like you, chose Mobius Institute for a good reason.
You will receive a digitally encrypted certificate, an ID card, and a personalized logo that you should use in email signatures and elsewhere that you want people to know about your achievements.

MAY I TAKE ONE OF YOUR COURSES IF I AM NOT INTERESTED IN BECOMING CERTIFIED OR IF I HAVE INSUFFICIENT EXPERIENCE FOR CERTIFICATION?
Yes, our courses are open to the public, regardless of experience. If you are involved in vibration analysis or rotating machinery in any capacity, such as sales, marketing, engineering, design, or reliability, you will come away with a far better understanding of how machines are monitored, how faults develop, and what can be done to determine what faults actually exist in a machine. All attendees receive certificates of completion. Candidates without sufficient experience will still receive a certificate if they pass the exam, but it will note that their experience was insufficient for ISO certification at the time.
AFTER I ATTEND YOUR COURSE AND TAKE THE EXAM, WHEN WILL I RECEIVE NOTIFICATIONS AS TO WHETHER I PASSED, AND WHEN WILL I RECEIVE MY CERTIFICATE?
You will receive notification of your results 5-10 days after the exam has been received at our Australian office. If you have passed the exam and met all certification requirements, you will receive your Digital Certificate 10-15 days after your exam results notification email.
HOW LONG IS THE CERTIFICATION VALID?
Vibration analysis certification is valid for five (5) years.
HOW DO I RENEW MY CERTIFICATION?
We will endeavor to contact you before your certification expires, therefore it is important that you keep your TMS records up to date (TMS is the training management system you will use to register for the course and for certification). If you change roles, it is essential that you update your records. We also invite you to set a reminder in your calendar for five years hence to contact us.
HOW DO I QUALIFY FOR RENEWAL?
As per the standard, we do not require you to attend our conferences or take our courses, however, we hope you will take advantage of www.mobiusconnect.com and the sites linked to Mobius CONNECT so that your knowledge remains current. These sites are free of charge. When it is time to renew your certification, we will ask you to nominate an independent person who can verify that you are still active as a vibration analyst. There will be a small fee to renew your digital certificate and to renew your certification status with the accreditation body.
WHAT ARE THE EXPERIENCE REQUIREMENTS FOR VCAT IV?
You must have 60 months of experience in vibration data collection and analysis. You will be asked to nominate an independent person who can verify that you have that experience.
Certification to VCAT IV also requires previous certification to VCAT III by a MIBoC approved certification body.
