  1. Enormously Valuable Course!



    In addition to working with you as our uncertainty budget consultant, our firm wanted to take advantage of your class. As I moved through the course, I realized most of the questions I’d either asked or planned on asking are covered in your course. I find the instruction on the process to be enormously valuable, but I’m still glad I hired you to do our budgets!

    Thank you for your intellect and the ability to transfer a portion of your knowledge.

    Best regards,

  2. Through lesson and helpful instructor


    I find this course very interesting for absolute beginners and quite easy to follow. There are times when it seems to be confusing especially when the lesson/assignments are not the same as your parameters, but emailing Rick will help you get back on track.

  3. Best and Clear Uncertainty Training


    The course makes us to clearly understand the measurement of uncertainty from the basics with very clear explanations with valuable reasons, suggestions and clarifications. Videos and Assignments changed me from a doubtful person to a confident man.

    The complete course material was available on the first day of the training. Helped to go through the entire course content.

    I strongly recommend the course to all who are really interested to know, to learn and do measurement uncertainty.

  4. Best Uncertainty Training Around


    Being exposed to the calibration and measurement industry as long as I have, I have NEVER had a training course cover as much detail as this. Rick is always more than willing to help answer any questions you may have about anything – even if it’s not specifically referenced in his course. The examples are well placed, the course content in clear and concise, and it can be completed online in your own time! I never thought I’d get as far as I did, but I’m now able to confidently create uncertainty budgets to assist my company with 17025 compliance, and it’s a great feeling. 5 stars to you, Rick – I can’t thank you enough for all of your help.

  5. This course deserves more than 5 stars


    I have spent a monumental amount of time researching measurement uncertainty. There are many resources available online. However, the issue is that you will rarely find any two sources that agree on everything regarding measurement uncertainties. This makes researching measurement uncertainties on your own overwhelmingly confusing and extremely ineffective.

    I have always excelled at math. I took four advanced math courses in high school just to avoid taking a foreign language. I was a nuclear reactor operator in the United States Navy. Yet, the process of calculating measurement uncertainties has always eluded me.

    That is, until I enrolled in the measurement uncertainty class offered at This course is BY FAR the best measurement uncertainty course available. The courses are very well put together and organized. The instructor is very knowledgeable, helpful, and responsive.

    When I first read the GUM, it was basically useless to me and none of it made sense because I did not understand the math involved. I now have a much deeper understanding of the math and fundamentals behind uncertainty calculations, and that is entirely because of the training course from

    I absolutely recommend this course to all who consider themselves calibration and metrology professionals.

  6. 5

    The course was definitely useful. I feel beter prepared now to assess uncertainty for the different methods used in our lab and more in control of the uncertainty parameters.

  7. 5

    This course looks really good based on the intro material.

  8. 5

    This is a great course for anyone wanting a detailed understanding of calculating measurement uncertainty! Thank you ISO Budgets!

  9. 5

    Excellent course for understanding the steps to create and evaluate CMC’s for labs. Response to questions is timely and helpful.

  10. 5

    Great Course. The content and delivery style are easy to follow.
    My biggest takeaways was the acquired confidence in calculating measurement uncertainty.
    I have ended the course feeling motivated to whip out my new skills and go on a new budget adventure.
    Recommending this course wholeheartedly.

  11. 5

    The course is very informative. All of the assignments are worked through by the instructor to help show the interaction of each calculation. I would highly recommend this course to anyone working in a calibration laboratory.

  12. 5

    Working through this course was a very positive experience – the instructor is responsive, willing to answer questions, and provides feedback on each assignment. It is immediately obvious that a great deal of time and effort has been put in to structuring the course and putting together supplemental materials to assist students. I finished with, what I feel, is a very strong foundation and understanding of what makes an uncertainty budget and how to collect the information necessary to develop more.
    The lessons are broken up in meaningful ways and the progression feels appropriate. A wide variety of examples are demonstrated, and in more ways than one – the instructor provides demonstrations of how to perform calculations and collect information in corresponding assignment videos and literature for each lesson. References and useful tips are included to help the student identify how the uncertainty budget they create compares to national labs and other accredited bodies.

  13. 5

    Creating an uncertainty budget from start to finish can be an intimidating challenge. Mr. Hogan has created a systematic, step by step approach that breaks the process down into easier to understand concepts. Each lesson is clear and concise, with excellent examples and tools that walk the student through the process of building an uncertainty budget. I highly recommend the course.

  14. 5

    Mr Hogan has tremendous knowledge and insight to the industry as a whole and makes Measurement Uncertainty Applications in an easy to understand process.

  15. 5

    Great Information, and help every step of the way. I now feel I am ready to start calculating MU.

  16. 5

    “Great course. Mr. Hogan takes the mystery out of the application of measurement uncertainty and the application of it. I highly recommend this course to everyone.”

  17. 5

    The course was well taught by Richard, he did a great job of watering down the confusing points to point out what they really are looking for in those section. The course helped clear up a lot of things for me and I will be strongly recommending to others who are interested. I really enjoyed how this course was taught and how the schedule went. Richard is also very easy to get in touch with to ask any questions.

  18. 5

    This was a great course

    Congratulations Richard.

  19. 5

    A good introductory course to measurement of uncertainty.

  20. 5

    The course presented detail material using simple terms. The project work in Excel kept the participant engaged while reinforcing the lessons. The overall summary at Lesson 9 tied the elements back together in context. The last lessons guided the participant on practical application of the calculations and presentation of the information that was developed during the course. Well Done!

  21. 5

    Great course with a lot of information given, very easy to follow along with and went at a good pace with lessons and projects.

  22. 5

    Very thorough, clear and concise. Great detail and examples are very helpful. Highly recommend *****

  23. 5

    This course is accessible to students and thorough. Mr. Hogan explains the calculations well as he walks the students from the introductory concepts of uncertainty to the completion of an uncertainty budget ready for submission for ISO 17025 approval. I greatly appreciated his focus on developing a robust uncertainty budget that was defensible to auditors, and on many occasions pointing out common problem areas that assessors flag. The documentation is first rate and will provide a valuable reference.

  24. 5

    A thorough, comprehensive and user-friendly course on calculating measurement uncertainty. This ISO Budgets course not only provides you with all the tools you need to calculate MU and compose CMC Budgets, but also references numerous sources of additional guidance. Richard Hogan has provided a solid MU course with materials you will continue to utilize going forward.

  25. 5

    Course was very informative. Very helpful.

  26. 4

    Its a great course, and very well explained.

  27. Excellent Self-Paced Course for Beginner or as Refresher


    Mr. Hogan is currently consulting with our small organization to create uncertainty budgets and establish CMC’s in our pursuit of accreditation. While I am familiar with many things Metrology, I am by no means an expert. This course provided me with the additional information and tools to understand, interpret and confidently use the uncertainty analyses and CMC’s he has provided, as well as simplifying the creation of additional budgets on our own.
    The videos were concise yet covered the basics very well, and the downloadable slides and guides for each section are excellent. Compared to many basic and not so basic uncertainty classes I’ve attended over the years, this one was money well spent—and I can say this because it was my money that foot the bill for this class, not my company’s.

  28. Extremely informative course


    A well structured course, presented in an easy to follow process, that provides all the necessary detail and equips you with the tools to produce your own Expanded Uncertainties necessary for your accreditation or Test/Calibration requirements. Thank you Rick.

  29. Measurement Uncertainty


    Great course with lots of extra material referenced. RIck is always helpful and gets back to you in a timely manner.

  30. Measurement of Uncertainty Course


    Excellent way to receive formal training in measurement uncertainty! This class really helped me standardize my own methods and provided a ton of resources, clarification, and perspective on this subject. Everything that I expected to find was here, as well as quite a bit more that lead to much needed epiphanies regarding analysis methods!
    Very good course, absolutely recommended to anyone who feels that they need their knowledge thouroughly rounded out.
